Two more answers are brought to explain what opinion of Rabbi Yehuda was Rav following? The gemara concludes that is was about the issue of one who cooks on Shabbat unintentionally. What types of knives or other sharp implements can/can’t be used to shechita?

Chullin 15
כל נרות של מתכת מטלטלין חוץ מן הנר שהדליקו בו באותה שבת
One may move all metal lamps on Shabbat, even old ones, because they do not become repugnant like earthenware lamps, except for a metal lamp that one kindled on that same Shabbat and that was burning when Shabbat began, which it is prohibited to move for the entire Shabbat due to the prohibition against extinguishing.
ודלמא שאני התם דהוא דחי ליה בידים
The Gemara rejects that analogy. And perhaps it is different there, in the case of the burning lamp, as he set it aside by direct action when he kindled the lamp. By contrast, in the case of an animal, he did not set it aside, and therefore, perhaps once it is slaughtered it is permitted.
אלא אמר רב אשי רבי יהודה דמבשל היא דתנן המבשל בשבת בשוגג יאכל במזיד לא יאכל דברי רבי מאיר
Rather, Rav Ashi said: When Rav said that the halakha that consumption of the animal is prohibited for that day is the opinion of Rabbi Yehuda, the reference is to the opinion of Rabbi Yehuda with regard to one who cooks, as we learned in a baraita: With regard to one who cooks on Shabbat, if he did so unwittingly, he may eat what he cooked. If he acted intentionally, he may not eat what he cooked. This is the statement of Rabbi Meir.
רבי יהודה אומר בשוגג יאכל במוצאי שבת במזיד לא יאכל עולמית
Rabbi Yehuda says: If he cooked the food unwittingly, he may eat it at the conclusion of Shabbat, as the Sages penalized even one who sinned unwittingly by prohibiting him from deriving immediate benefit from the dish that he cooked. If he cooked it intentionally, he may never eat from it.
רבי יוחנן הסנדלר אומר בשוגג יאכל למוצאי שבת לאחרים ולא לו במזיד לא יאכל עולמית לא לו ולא לאחרים
Rabbi Yoḥanan HaSandlar says: If he acted unwittingly, the food may be eaten at the conclusion of Shabbat by others, but not by him. If he cooked the food intentionally, it may never be eaten, neither by him nor by others. According to Rav, the mishna is referring to a case where one slaughtered the animal unwittingly. According to Rabbi Yehuda, the slaughter is valid but it is prohibited to eat the animal on Shabbat.
ונוקמה במזיד ורבי מאיר
The Gemara challenges this: And let us interpret the mishna as referring to a case where he slaughtered the animal intentionally, and explain that it is in accordance with the opinion of Rabbi Meir, who rules that eating the animal in such a case is permitted only after the conclusion of Shabbat.
לא סלקא דעתך דקתני דומיא דיום הכפורים מה יום הכפורים לא שנא בשוגג ולא שנא במזיד לא אכיל אף הכא נמי לא שנא בשוגג ולא שנא במזיד לא אכיל
The Gemara responds: That possibility should not enter your mind, as the case of slaughter on Shabbat is juxtaposed to and taught in a manner similar to the case of slaughter on Yom Kippur. Just as with regard to slaughter on Yom Kippur, it is no different whether one slaughtered it unwittingly and it is no different whether he slaughtered it intentionally, he may not eat it that day due to the fast, so too here, with regard to slaughter on Shabbat, it is no different whether he slaughtered it unwittingly and it is no different whether he slaughtered it intentionally, he may not eat it that day. Rabbi Meir, though, deems it permitted for one who cooked unwittingly to eat the cooked food on Shabbat.
ומי מצית מוקמת לה בשוגג ורבי יהודה והא אף על פי שמתחייב בנפשו קתני הכי קאמר אע”פ דבמזיד מתחייב בנפשו הוא הכא דבשוגג שחיטתו כשרה
The Gemara asks: And can you interpret the mishna as referring to a case of unwitting slaughter and in accordance with the opinion of Rabbi Yehuda? But isn’t it taught in the mishna: Although he is liable to receive the death penalty? One is liable to be executed only if he intentionally performs labor on Shabbat. The Gemara answers that this is what the mishna is saying: Although if he slaughtered it intentionally he is liable to receive the death penalty, here, in a case where he slaughtered the animal unwittingly, his slaughter is valid.
ונוקמה כרבי יוחנן הסנדלר דאמר לא שנא בשוגג ולא שנא במזיד לא אכיל רבי יוחנן הסנדלר קמפליג במוצאי שבת לאחרים ולא לו תנא דידן שחיטתו כשרה קתני לא שנא לו ולא שנא לאחרים
The Gemara challenges: And let us interpret the mishna in accordance with the opinion of Rabbi Yoḥanan HaSandlar, who says: It is no different whether he cooked unwittingly and it is no different whether he cooked intentionally; he may not eat it on Shabbat. The Gemara explains: Rabbi Yoḥanan HaSandlar draws a distinction with regard to the conclusion of Shabbat, in that he permits eating food cooked on Shabbat for others and not for him, while the tanna of our mishna teaches: His slaughter is valid, without qualification, indicating that with regard to his ruling it is no different for him and it is no different for others.
תני תנא קמיה דרב המבשל בשבת בשוגג יאכל במזיד לא יאכל ומשתיק ליה רב
§ The tanna taught a baraita before Rav: One who cooks on Shabbat unwittingly may eat the food that he cooked; if he did so intentionally, he may not eat the food that he cooked, and Rav silenced him.
מאי טעמא משתיק ליה אילימא משום דסבירא ליה כרבי יהודה ותנא תני כרבי מאיר משום דסבירא ליה כרבי יהודה מאן דתני כרבי מאיר משתיק ליה
The Gemara asks: What is the reason that Rav silenced him? If we say it is because Rav holds in accordance with the opinion of Rabbi Yehuda and the tanna taught the baraita in accordance with the opinion of Rabbi Meir, can it be that merely because he holds in accordance with the opinion of Rabbi Yehuda he silences one who teaches a baraita in accordance with the opinion of Rabbi Meir?
ועוד מי סבר לה כרבי יהודה והאמר רב חנן בר אמי כי מורי להו רב לתלמידיה מורי להו כר’ מאיר וכי דריש בפירקא דריש כרבי יהודה משום עמי הארץ
And furthermore, does Rav hold in accordance with the opinion of Rabbi Yehuda? But doesn’t Rav Ḥanan bar Ami say: When Rav issues a ruling to his students, he issues a ruling in accordance with the opinion of Rabbi Meir, and when he teaches in his public lecture delivered on the Festival, he teaches in accordance with the opinion of Rabbi Yehuda, due to his concern that the ignoramuses would treat the prohibition of labor on Shabbat with disdain?
וכי תימא תנא בפירקיה תנא קמיה אטו כולי עלמא לתנא צייתי לאמורא צייתי
And if you would say that the tanna taught the baraita before Rav during the public lecture and Rav silenced him so that the ignoramuses would not learn from him, is that to say that everyone attending the public lecture listens to the tanna who is citing the baraita? There is no need to silence the tanna, because they listen to the disseminator [amora], the Sage who repeats what he hears from Rav loudly for the benefit of those attending the lecture, and the amora quoted Rav’s ruling in accordance with the opinion of Rabbi Yehuda.
אמר רב נחמן בר יצחק תנא שוחט תנא קמיה דרב השוחט בשבת בשוגג יאכל במזיד לא יאכל אמר ליה מאי דעתיך כרבי מאיר עד כאן לא קשרי רבי מאיר אלא במבשל דראוי לכוס אבל שוחט דאין ראוי לכוס לא
Rav Naḥman bar Yitzḥak said: The tanna taught the halakha of one who slaughters before Rav: One who slaughters an animal on Shabbat unwittingly may eat from the slaughtered animal; if he slaughtered it intentionally, he may not eat from the slaughtered animal. Rav said to the tanna: What do you think, that the halakha is in accordance with the opinion of Rabbi Meir? Rabbi Meir deems eating permitted only in the case of one who cooks unwittingly on Shabbat, as even before he cooks the food it is fit to be chewed [lakhos], i.e., to be eaten uncooked, in a permitted manner, and therefore it was not set aside from use when Shabbat began. But in the case of one who slaughters an animal, where the meat was not fit to chew, Rabbi Meir does not permit eating it on Shabbat, because it was set aside from use on Shabbat.
והא מתניתין דשוחט הוא ואמר רב הונא דרש חייא בר רב משמיה דרב אסורה באכילה ליומא ונסבין חבריא למימר רבי יהודה היא הא רבי מאיר שרי
The Gemara asks: But isn’t the mishna addressing the case of one who slaughters an animal, and Rav Huna says that Ḥiyya bar Rav taught in the name of Rav: Consumption of the animal is prohibited for that day, and the members of the company of Sages, i.e., those in the academy, tended to say that this halakha is the opinion of Rabbi Yehuda, from which it may be inferred: But Rabbi Meir permits consumption of the slaughtered animal even on Shabbat, and he is not concerned that the animal was set aside from use when Shabbat began?
כי שרי רבי מאיר
The Gemara answers: When Rabbi Meir permits consumption of the slaughtered animal even on Shabbat,
כגון שהיה לו חולה מבעוד יום
it is in a case where one had a critically ill person in his household while it was still day, before Shabbat, as it is permitted to slaughter the animal for such a person even on Shabbat. Therefore, the unslaughtered animal was not set aside from use.
אי הכי מאי טעמא דרבי יהודה דאסר כגון שהיה לו חולה והבריא
The Gemara asks: If so, what is the reason that Rabbi Yehuda prohibited consumption of the meat on Shabbat? The Gemara answers: He issued this ruling in a case where one had a critically ill person in his household before Shabbat and that person recovered. In that case, although the unslaughtered animal was not set aside from use when Shabbat began, it is prohibited to slaughter it on Shabbat. According to Rabbi Yehuda, if he slaughtered it unwittingly, its consumption is prohibited on Shabbat.
וכי הא דאמר רב אחא בר אדא אמר רב ואמרי לה אמר רבי יצחק בר אדא אמר רב השוחט לחולה בשבת אסור לבריא המבשל לחולה בשבת מותר לבריא
And that which Rav silenced the tanna for not stating that an unslaughtered animal is set aside from use, even when the prohibited labor of slaughter was performed unwittingly, is in accordance with that which Rav Aḥa bar Adda says that Rav says, and some say it is that which Rabbi Yitzḥak bar Adda says that Rav says: In the case of one who slaughters an animal to feed an ill person on Shabbat, it is prohibited for a healthy person to partake of the slaughtered animal on Shabbat. In a case of one who cooks food to feed an ill person on Shabbat, it is permitted for a healthy person to partake of that food.
מאי טעמא האי ראוי לכוס והאי אינו ראוי לכוס
What is the reason for this distinction? This food was fit to be chewed before it was cooked, and therefore it was not set aside from use when Shabbat began, and the meat of that animal was not fit to be chewed before the animal was slaughtered, and therefore it was set aside from use when Shabbat began.
אמר רב פפא פעמים שהשוחט מותר כגון שהיה לו חולה מבעוד יום מבשל אסור כגון שקצץ לו דלעת
Rav Pappa says: There are times when one slaughters for an ill person on Shabbat and it is permitted for a healthy person to eat the meat on Shabbat, such as where he had a critically ill person in his household before Shabbat and the animal was designated for slaughter while it was still day, before Shabbat; in that case, it was not set aside from use. And there are times when one cooks on Shabbat for an ill person and it is prohibited for a healthy person to eat the food on Shabbat, such as where one cut a gourd that was attached to the ground for the ill person on Shabbat. Because it is prohibited to detach the gourd on Shabbat, it is set aside from use and forbidden.
אמר רב דימי מנהרדעא הלכתא השוחט לחולה בשבת מותר לבריא באומצא מ”ט כיון דאי אפשר לכזית בשר בלא שחיטה כי קא שחיט אדעתא דחולה קא שחיט המבשל לחולה בשבת אסור לבריא גזירה שמא ירבה בשבילו:
Rav Dimi of Neharde’a says that the halakha is: In the case of one who slaughters for an ill person on Shabbat, it is permitted for a healthy person to eat the raw meat [be’umtza]. What is the reason that it is permitted? Since it is impossible for an olive-bulk of meat to be permitted without slaughter of the entire animal, when he slaughters the animal, he slaughters it with the ill person in mind. Since slaughter of the animal was permitted, all its meat is permitted even for a healthy person. In the case of one who cooks for an ill person on Shabbat, it is prohibited for a healthy person to eat the food on Shabbat. What is the reason that it is prohibited? It is due to a rabbinic decree lest he increase the amount of food that he is cooking on behalf of the healthy person.
מתני׳ השוחט במגל יד בצור ובקנה שחיטתו כשרה
MISHNA: In the case of one who slaughters an animal with the smooth side of a hand sickle, which has both a smooth and a serrated side, or with a sharpened flint, or with a reed that was cut lengthwise and sharpened, his slaughter is valid.
הכל שוחטין ולעולם שוחטין ובכל שוחטין חוץ ממגל קציר והמגירה והשינים והציפורן מפני שהם חונקין:
All slaughter [hakkol shoḥatin], and one may always slaughter, and one may slaughter with any item that cuts, except for the serrated side of the harvest sickle, a saw, the teeth of an animal when attached to its jawbone, and a fingernail, because they are serrated and they consequently strangle the animal and do not cut its windpipe and gullet as required.
גמ׳ השוחט דיעבד אין לכתחלה לא בשלמא במגל יד דלמא אתי למעבד באידך גיסא אלא צור וקנה לכתחלה לא ורמינהי בכל שוחטין בין בצור בין בזכוכית בין בקרומית של קנה
GEMARA: The Gemara notes that the language of the mishna, which states: One who slaughters an animal with a hand sickle, with a flint, or with a reed, rather than: One may slaughter, indicates that after the fact, yes, the slaughter is valid, but one may not slaughter with those blades ab initio. The Gemara asks: Granted, one may not slaughter it with a hand sickle, lest he come to perform the slaughter with the other, serrated, side; but as a flint and a reed have no serrated side, is it so that one may not slaughter with those ab initio? And the Gemara raises a contradiction from a baraita: One may slaughter with any item that cuts, whether with a flint, or with glass shards, or with the stalk of a reed.
לא קשיא כאן בתלוש כאן במחובר דאמר רב כהנא השוחט במחובר לקרקע רבי פוסל ור’ חייא מכשיר עד כאן לא קא מכשיר רבי חייא אלא בדיעבד אבל לכתחלה לא
The Gemara answers: This is not difficult. There, where the baraita permits slaughter ab initio, it is referring to slaughter with a flint and a reed when they are detached. Here, where the mishna says that the slaughter is valid only after the fact, it is referring to slaughter with a flint and a reed when they are attached to the ground, as Rav Kahana says: In the case of one who slaughters with a blade that is attached to the ground, Rabbi Yehuda HaNasi deems the slaughter not valid and Rabbi Ḥiyya deems it valid. The Gemara infers: Even Rabbi Ḥiyya deems the slaughter valid only after the fact; but one may not do so ab initio.
במאי אוקימתא כרבי חייא ודיעבד אלא הא דתניא בכל שוחטין בין בתלוש בין במחובר בין שהסכין למעלה וצואר בהמה למטה בין שהסכין למטה וצואר בהמה למעלה מני לא רבי ולא ר’ חייא אי ר’ חייא דיעבד אין לכתחלה לא אי רבי דיעבד נמי לא
In accordance with which opinion did you interpret the mishna? Is it in accordance with the opinion of Rabbi Ḥiyya, and the slaughter is valid after the fact? But if so, with regard to that which is taught in a baraita: One may slaughter with any item that cuts, whether with a blade that is detached from the ground or with a blade that is attached to the ground, whether the knife is above and the neck of the animal is below or the knife is below and the neck of the animal is above; in accordance with whose opinion is it? It is in accordance neither with the opinion of Rabbi Yehuda HaNasi nor with the opinion of Rabbi Ḥiyya. If one would claim that it is in accordance with the opinion of Rabbi Ḥiyya, he says: After the fact, yes, the slaughter is valid, but it is not permitted to slaughter in this manner ab initio. If one would claim that it is in accordance with the opinion of Rabbi Yehuda HaNasi, he says: Even after the fact, the slaughter is not valid.
לעולם רבי חייא ואפילו לכתחלה והאי דקמיפלגי בדיעבד להודיעך כחו דרבי
The Gemara answers: Actually, the baraita is in accordance with the opinion of Rabbi Ḥiyya, and he permits slaughter with these blades even ab initio. And the fact that the opinions of Rabbi Yehuda HaNasi and Rabbi Ḥiyya were formulated such that they disagree concerning the halakha after the fact is to convey to you the far-reaching nature of the opinion of Rabbi Yehuda HaNasi that the slaughter is not valid even after the fact.
ואלא מתניתין דקתני השוחט דיעבד אין לכתחלה לא מני לא רבי ולא רבי חייא אי רבי חייא אפילו לכתחלה אי רבי דיעבד נמי לא
But rather, the mishna here, which teaches: With regard to one who slaughters, after the fact, yes, it is valid, but it is not ab initio, in accordance with whose opinion is it? It is in accordance neither with the opinion of Rabbi Yehuda HaNasi nor with the opinion of Rabbi Ḥiyya. If one would claim that it is in accordance with the opinion of Rabbi Ḥiyya, he says: The slaughter is permitted even ab initio. If one would claim that it is in accordance with the opinion of Rabbi Yehuda HaNasi, he says: Even after the fact, the slaughter is not valid.
לעולם רבי חייא ואפילו לכתחלה ומתניתין דקתני השוחט רבי היא
The Gemara answers: Actually, Rabbi Ḥiyya holds that it is permitted to slaughter with these blades, and even ab initio; and the mishna here, which teaches: One who slaughters, is in accordance with the opinion of Rabbi Yehuda HaNasi.
קשיא דרבי אדרבי לא קשיא כאן במחובר מעיקרו כאן בתלוש ולבסוף חיברו
The Gemara objects: This is difficult, as there is a contradiction between one statement of Rabbi Yehuda HaNasi and another statement of Rabbi Yehuda HaNasi, as in his dispute with Rabbi Ḥiyya he holds that the slaughter is not valid. The Gemara answers: This contradiction is not difficult. There, in his dispute with Rabbi Ḥiyya, Rabbi Yehuda HaNasi holds that slaughter is not valid in a case where the blade was attached from the outset; here, in the mishna, Rabbi Yehuda HaNasi deems the slaughter valid after the fact in a case where the blade was detached and ultimately he reattached it.
ומנא תימרא דשני לן בין מחובר מעיקרו לתלוש ולבסוף חיברו דתניא השוחט במוכני שחיטתו כשרה במחובר לקרקע שחיטתו כשרה נעץ סכין בכותל ושחט בה שחיטתו כשרה היה צור יוצא מן הכותל או קנה עולה מאליו ושחט בו שחיטתו פסולה
The Gemara asks: And from where do you say that there is a difference for us between a blade that was attached from the outset and a blade that was detached and ultimately he reattached it? As it is taught in a baraita: With regard to one who slaughters with a mechanism [bemukhni] of a wheel with a knife attached to it, his slaughter is valid; with an item that is attached to the ground, his slaughter is valid; if one embedded a knife in a wall and slaughtered with it, his slaughter is valid. If there was a flint emerging from a wall or a reed arising from the ground on its own and he slaughtered with it, his slaughter is not valid.

The Hadran Women’s Tapestry
Meet the diverse women learning Gemara at Hadran and hear their stories.
Robin Zeiger
Tel Aviv, Israel
I’ve been wanting to do Daf Yomi for years, but always wanted to start at the beginning and not in the middle of things. When the opportunity came in 2020, I decided: “this is now the time!” I’ve been posting my journey daily on social media, tracking my progress (#DafYomi); now it’s fully integrated into my daily routines. I’ve also inspired my partner to join, too!
Joséphine Altzman
Teaneck, United States
It’s hard to believe it has been over two years. Daf yomi has changed my life in so many ways and has been sustaining during this global sea change. Each day means learning something new, digging a little deeper, adding another lens, seeing worlds with new eyes. Daf has also fostered new friendships and deepened childhood connections, as long time friends have unexpectedly become havruta.
Joanna Rom

My first Talmud class experience was a weekly group in 1971 studying Taanit. In 2007 I resumed Talmud study with a weekly group I continue learning with. January 2020, I was inspired to try learning Daf Yomi. A friend introduced me to Daf Yomi for Women and Rabbanit Michelle Farber, I have kept with this program and look forward, G- willing, to complete the entire Shas with Hadran.
Lorri Lewis

I was inspired to start learning after attending the 2020 siyum in Binyanei Hauma. It has been a great experience for me. It’s amazing to see the origins of stories I’ve heard and rituals I’ve participated in my whole life. Even when I don’t understand the daf itself, I believe that the commitment to learning every day is valuable and has multiple benefits. And there will be another daf tomorrow!
Khaya Eisenberg
Jerusalem, Israel
My Daf journey began in August 2012 after participating in the Siyum Hashas where I was blessed as an “enabler” of others. Galvanized into my own learning I recited the Hadran on Shas in January 2020 with Rabbanit Michelle. That Siyum was a highlight in my life. Now, on round two, Daf has become my spiritual anchor to which I attribute manifold blessings.
Rina Goldberg
Englewood NJ, United States
I started learning when my brother sent me the news clip of the celebration of the last Daf Yomi cycle. I was so floored to see so many women celebrating that I wanted to be a part of it. It has been an enriching experience studying a text in a language I don’t speak, using background knowledge that I don’t have. It is stretching my learning in unexpected ways, bringing me joy and satisfaction.
Jodi Gladstone
Warwick, Rhode Island, United States
I decided to learn one masechet, Brachot, but quickly fell in love and never stopped! It has been great, everyone is always asking how it’s going and chering me on, and my students are always making sure I did the day’s daf.
Yafit Fishbach
Memphis, Tennessee, United States
After experiences over the years of asking to join gemara shiurim for men and either being refused by the maggid shiur or being the only women there, sometimes behind a mechitza, I found out about Hadran sometime during the tail end of Masechet Shabbat, I think. Life has been much better since then.
Madeline Cohen
London, United Kingdom
I started last year after completing the Pesach Sugiyot class. Masechet Yoma might seem like a difficult set of topics, but for me made Yom Kippur and the Beit HaMikdash come alive. Liturgy I’d always had trouble connecting with took on new meaning as I gained a sense of real people moving through specific spaces in particular ways. It was the perfect introduction; I am so grateful for Hadran!
Debbie Engelen-Eigles
Minnesota, United States
A Gemara shiur previous to the Hadran Siyum, was the impetus to attend it.It was highly inspirational and I was smitten. The message for me was התלמוד בידינו. I had decided along with my Chahsmonaim group to to do the daf and take it one daf at time- without any expectations at all. There has been a wealth of information, insights and halachik ideas. It is truly exercise of the mind, heart & Soul
Phyllis Hecht
Hashmonaim, Israel
At almost 70 I am just beginning my journey with Talmud and Hadran. I began not late, but right when I was called to learn. It is never too late to begin! The understanding patience of staff and participants with more experience and knowledge has been fabulous. The joy of learning never stops and for me. It is a new life, a new light, a new depth of love of The Holy One, Blessed be He.
Deborah Hoffman-Wade
Richmond, CA, United States
Ive been learning Gmara since 5th grade and always loved it. Have always wanted to do Daf Yomi and now with Michelle Farber’s online classes it made it much easier to do! Really enjoying the experience thank you!!
Lisa Lawrence
Neve Daniel, Israel
After all the hype on the 2020 siyum I became inspired by a friend to begin learning as the new cycle began.with no background in studying Talmud it was a bit daunting in the beginning. my husband began at the same time so we decided to study on shabbat together. The reaction from my 3 daughters has been fantastic. They are very proud. It’s been a great challenge for my brain which is so healthy!

It’s hard to believe it has been over two years. Daf yomi has changed my life in so many ways and has been sustaining during this global sea change. Each day means learning something new, digging a little deeper, adding another lens, seeing worlds with new eyes. Daf has also fostered new friendships and deepened childhood connections, as long time friends have unexpectedly become havruta.
Joanna Rom

Shortly after the death of my father, David Malik z”l, I made the commitment to Daf Yomi. While riding to Ben Gurion airport in January, Siyum HaShas was playing on the radio; that was the nudge I needed to get started. The “everyday-ness” of the Daf has been a meaningful spiritual practice, especial after COVID began & I was temporarily unable to say Kaddish at daily in-person minyanim.
Lisa S. Malik
Wynnewood, United States
In early January of 2020, I learned about Siyyum HaShas and Daf Yomi via Tablet Magazine’s brief daily podcast about the Daf. I found it compelling and fascinating. Soon I discovered Hadran; since then I have learned the Daf daily with Rabbanit Michelle Cohen Farber. The Daf has permeated my every hour, and has transformed and magnified my place within the Jewish Universe.
Lisa Berkelhammer
San Francisco, CA , United States
After being so inspired by the siyum shas two years ago, I began tentatively learning daf yomi, like Rabbanut Michelle kept saying – taking one daf at a time. I’m still taking it one daf at a time, one masechet at a time, but I’m loving it and am still so inspired by Rabbanit Michelle and the Hadran community, and yes – I am proud to be finishing Seder Mo’ed.
Caroline Graham-Ofstein
Bet Shemesh, Israel
I never thought I’d be able to do Daf Yomi till I saw the video of Hadran’s Siyum HaShas. Now, 2 years later, I’m about to participate in Siyum Seder Mo’ed with my Hadran community. It has been an incredible privilege to learn with Rabbanit Michelle and to get to know so many caring, talented and knowledgeable women. I look forward with great anticipation and excitement to learning Seder Nashim.
Caroline Ben-Ari
Karmiel, Israel
I learned Mishnayot more than twenty years ago and started with Gemara much later in life. Although I never managed to learn Daf Yomi consistently, I am learning since some years Gemara in depth and with much joy. Since last year I am studying at the International Halakha Scholars Program at the WIHL. I often listen to Rabbanit Farbers Gemara shiurim to understand better a specific sugyiah. I am grateful for the help and inspiration!

כל נרות של מתכת מטלטלין חוץ מן הנר שהדליקו בו באותה שבת
One may move all metal lamps on Shabbat, even old ones, because they do not become repugnant like earthenware lamps, except for a metal lamp that one kindled on that same Shabbat and that was burning when Shabbat began, which it is prohibited to move for the entire Shabbat due to the prohibition against extinguishing.
ודלמא שאני התם דהוא דחי ליה בידים
The Gemara rejects that analogy. And perhaps it is different there, in the case of the burning lamp, as he set it aside by direct action when he kindled the lamp. By contrast, in the case of an animal, he did not set it aside, and therefore, perhaps once it is slaughtered it is permitted.
אלא אמר רב אשי רבי יהודה דמבשל היא דתנן המבשל בשבת בשוגג יאכל במזיד לא יאכל דברי רבי מאיר
Rather, Rav Ashi said: When Rav said that the halakha that consumption of the animal is prohibited for that day is the opinion of Rabbi Yehuda, the reference is to the opinion of Rabbi Yehuda with regard to one who cooks, as we learned in a baraita: With regard to one who cooks on Shabbat, if he did so unwittingly, he may eat what he cooked. If he acted intentionally, he may not eat what he cooked. This is the statement of Rabbi Meir.
רבי יהודה אומר בשוגג יאכל במוצאי שבת במזיד לא יאכל עולמית
Rabbi Yehuda says: If he cooked the food unwittingly, he may eat it at the conclusion of Shabbat, as the Sages penalized even one who sinned unwittingly by prohibiting him from deriving immediate benefit from the dish that he cooked. If he cooked it intentionally, he may never eat from it.
רבי יוחנן הסנדלר אומר בשוגג יאכל למוצאי שבת לאחרים ולא לו במזיד לא יאכל עולמית לא לו ולא לאחרים
Rabbi Yoḥanan HaSandlar says: If he acted unwittingly, the food may be eaten at the conclusion of Shabbat by others, but not by him. If he cooked the food intentionally, it may never be eaten, neither by him nor by others. According to Rav, the mishna is referring to a case where one slaughtered the animal unwittingly. According to Rabbi Yehuda, the slaughter is valid but it is prohibited to eat the animal on Shabbat.
ונוקמה במזיד ורבי מאיר
The Gemara challenges this: And let us interpret the mishna as referring to a case where he slaughtered the animal intentionally, and explain that it is in accordance with the opinion of Rabbi Meir, who rules that eating the animal in such a case is permitted only after the conclusion of Shabbat.
לא סלקא דעתך דקתני דומיא דיום הכפורים מה יום הכפורים לא שנא בשוגג ולא שנא במזיד לא אכיל אף הכא נמי לא שנא בשוגג ולא שנא במזיד לא אכיל
The Gemara responds: That possibility should not enter your mind, as the case of slaughter on Shabbat is juxtaposed to and taught in a manner similar to the case of slaughter on Yom Kippur. Just as with regard to slaughter on Yom Kippur, it is no different whether one slaughtered it unwittingly and it is no different whether he slaughtered it intentionally, he may not eat it that day due to the fast, so too here, with regard to slaughter on Shabbat, it is no different whether he slaughtered it unwittingly and it is no different whether he slaughtered it intentionally, he may not eat it that day. Rabbi Meir, though, deems it permitted for one who cooked unwittingly to eat the cooked food on Shabbat.
ומי מצית מוקמת לה בשוגג ורבי יהודה והא אף על פי שמתחייב בנפשו קתני הכי קאמר אע”פ דבמזיד מתחייב בנפשו הוא הכא דבשוגג שחיטתו כשרה
The Gemara asks: And can you interpret the mishna as referring to a case of unwitting slaughter and in accordance with the opinion of Rabbi Yehuda? But isn’t it taught in the mishna: Although he is liable to receive the death penalty? One is liable to be executed only if he intentionally performs labor on Shabbat. The Gemara answers that this is what the mishna is saying: Although if he slaughtered it intentionally he is liable to receive the death penalty, here, in a case where he slaughtered the animal unwittingly, his slaughter is valid.
ונוקמה כרבי יוחנן הסנדלר דאמר לא שנא בשוגג ולא שנא במזיד לא אכיל רבי יוחנן הסנדלר קמפליג במוצאי שבת לאחרים ולא לו תנא דידן שחיטתו כשרה קתני לא שנא לו ולא שנא לאחרים
The Gemara challenges: And let us interpret the mishna in accordance with the opinion of Rabbi Yoḥanan HaSandlar, who says: It is no different whether he cooked unwittingly and it is no different whether he cooked intentionally; he may not eat it on Shabbat. The Gemara explains: Rabbi Yoḥanan HaSandlar draws a distinction with regard to the conclusion of Shabbat, in that he permits eating food cooked on Shabbat for others and not for him, while the tanna of our mishna teaches: His slaughter is valid, without qualification, indicating that with regard to his ruling it is no different for him and it is no different for others.
תני תנא קמיה דרב המבשל בשבת בשוגג יאכל במזיד לא יאכל ומשתיק ליה רב
§ The tanna taught a baraita before Rav: One who cooks on Shabbat unwittingly may eat the food that he cooked; if he did so intentionally, he may not eat the food that he cooked, and Rav silenced him.
מאי טעמא משתיק ליה אילימא משום דסבירא ליה כרבי יהודה ותנא תני כרבי מאיר משום דסבירא ליה כרבי יהודה מאן דתני כרבי מאיר משתיק ליה
The Gemara asks: What is the reason that Rav silenced him? If we say it is because Rav holds in accordance with the opinion of Rabbi Yehuda and the tanna taught the baraita in accordance with the opinion of Rabbi Meir, can it be that merely because he holds in accordance with the opinion of Rabbi Yehuda he silences one who teaches a baraita in accordance with the opinion of Rabbi Meir?
ועוד מי סבר לה כרבי יהודה והאמר רב חנן בר אמי כי מורי להו רב לתלמידיה מורי להו כר’ מאיר וכי דריש בפירקא דריש כרבי יהודה משום עמי הארץ
And furthermore, does Rav hold in accordance with the opinion of Rabbi Yehuda? But doesn’t Rav Ḥanan bar Ami say: When Rav issues a ruling to his students, he issues a ruling in accordance with the opinion of Rabbi Meir, and when he teaches in his public lecture delivered on the Festival, he teaches in accordance with the opinion of Rabbi Yehuda, due to his concern that the ignoramuses would treat the prohibition of labor on Shabbat with disdain?
וכי תימא תנא בפירקיה תנא קמיה אטו כולי עלמא לתנא צייתי לאמורא צייתי
And if you would say that the tanna taught the baraita before Rav during the public lecture and Rav silenced him so that the ignoramuses would not learn from him, is that to say that everyone attending the public lecture listens to the tanna who is citing the baraita? There is no need to silence the tanna, because they listen to the disseminator [amora], the Sage who repeats what he hears from Rav loudly for the benefit of those attending the lecture, and the amora quoted Rav’s ruling in accordance with the opinion of Rabbi Yehuda.
אמר רב נחמן בר יצחק תנא שוחט תנא קמיה דרב השוחט בשבת בשוגג יאכל במזיד לא יאכל אמר ליה מאי דעתיך כרבי מאיר עד כאן לא קשרי רבי מאיר אלא במבשל דראוי לכוס אבל שוחט דאין ראוי לכוס לא
Rav Naḥman bar Yitzḥak said: The tanna taught the halakha of one who slaughters before Rav: One who slaughters an animal on Shabbat unwittingly may eat from the slaughtered animal; if he slaughtered it intentionally, he may not eat from the slaughtered animal. Rav said to the tanna: What do you think, that the halakha is in accordance with the opinion of Rabbi Meir? Rabbi Meir deems eating permitted only in the case of one who cooks unwittingly on Shabbat, as even before he cooks the food it is fit to be chewed [lakhos], i.e., to be eaten uncooked, in a permitted manner, and therefore it was not set aside from use when Shabbat began. But in the case of one who slaughters an animal, where the meat was not fit to chew, Rabbi Meir does not permit eating it on Shabbat, because it was set aside from use on Shabbat.
והא מתניתין דשוחט הוא ואמר רב הונא דרש חייא בר רב משמיה דרב אסורה באכילה ליומא ונסבין חבריא למימר רבי יהודה היא הא רבי מאיר שרי
The Gemara asks: But isn’t the mishna addressing the case of one who slaughters an animal, and Rav Huna says that Ḥiyya bar Rav taught in the name of Rav: Consumption of the animal is prohibited for that day, and the members of the company of Sages, i.e., those in the academy, tended to say that this halakha is the opinion of Rabbi Yehuda, from which it may be inferred: But Rabbi Meir permits consumption of the slaughtered animal even on Shabbat, and he is not concerned that the animal was set aside from use when Shabbat began?
כי שרי רבי מאיר
The Gemara answers: When Rabbi Meir permits consumption of the slaughtered animal even on Shabbat,
כגון שהיה לו חולה מבעוד יום
it is in a case where one had a critically ill person in his household while it was still day, before Shabbat, as it is permitted to slaughter the animal for such a person even on Shabbat. Therefore, the unslaughtered animal was not set aside from use.
אי הכי מאי טעמא דרבי יהודה דאסר כגון שהיה לו חולה והבריא
The Gemara asks: If so, what is the reason that Rabbi Yehuda prohibited consumption of the meat on Shabbat? The Gemara answers: He issued this ruling in a case where one had a critically ill person in his household before Shabbat and that person recovered. In that case, although the unslaughtered animal was not set aside from use when Shabbat began, it is prohibited to slaughter it on Shabbat. According to Rabbi Yehuda, if he slaughtered it unwittingly, its consumption is prohibited on Shabbat.
וכי הא דאמר רב אחא בר אדא אמר רב ואמרי לה אמר רבי יצחק בר אדא אמר רב השוחט לחולה בשבת אסור לבריא המבשל לחולה בשבת מותר לבריא
And that which Rav silenced the tanna for not stating that an unslaughtered animal is set aside from use, even when the prohibited labor of slaughter was performed unwittingly, is in accordance with that which Rav Aḥa bar Adda says that Rav says, and some say it is that which Rabbi Yitzḥak bar Adda says that Rav says: In the case of one who slaughters an animal to feed an ill person on Shabbat, it is prohibited for a healthy person to partake of the slaughtered animal on Shabbat. In a case of one who cooks food to feed an ill person on Shabbat, it is permitted for a healthy person to partake of that food.
מאי טעמא האי ראוי לכוס והאי אינו ראוי לכוס
What is the reason for this distinction? This food was fit to be chewed before it was cooked, and therefore it was not set aside from use when Shabbat began, and the meat of that animal was not fit to be chewed before the animal was slaughtered, and therefore it was set aside from use when Shabbat began.
אמר רב פפא פעמים שהשוחט מותר כגון שהיה לו חולה מבעוד יום מבשל אסור כגון שקצץ לו דלעת
Rav Pappa says: There are times when one slaughters for an ill person on Shabbat and it is permitted for a healthy person to eat the meat on Shabbat, such as where he had a critically ill person in his household before Shabbat and the animal was designated for slaughter while it was still day, before Shabbat; in that case, it was not set aside from use. And there are times when one cooks on Shabbat for an ill person and it is prohibited for a healthy person to eat the food on Shabbat, such as where one cut a gourd that was attached to the ground for the ill person on Shabbat. Because it is prohibited to detach the gourd on Shabbat, it is set aside from use and forbidden.
אמר רב דימי מנהרדעא הלכתא השוחט לחולה בשבת מותר לבריא באומצא מ”ט כיון דאי אפשר לכזית בשר בלא שחיטה כי קא שחיט אדעתא דחולה קא שחיט המבשל לחולה בשבת אסור לבריא גזירה שמא ירבה בשבילו:
Rav Dimi of Neharde’a says that the halakha is: In the case of one who slaughters for an ill person on Shabbat, it is permitted for a healthy person to eat the raw meat [be’umtza]. What is the reason that it is permitted? Since it is impossible for an olive-bulk of meat to be permitted without slaughter of the entire animal, when he slaughters the animal, he slaughters it with the ill person in mind. Since slaughter of the animal was permitted, all its meat is permitted even for a healthy person. In the case of one who cooks for an ill person on Shabbat, it is prohibited for a healthy person to eat the food on Shabbat. What is the reason that it is prohibited? It is due to a rabbinic decree lest he increase the amount of food that he is cooking on behalf of the healthy person.
מתני׳ השוחט במגל יד בצור ובקנה שחיטתו כשרה
MISHNA: In the case of one who slaughters an animal with the smooth side of a hand sickle, which has both a smooth and a serrated side, or with a sharpened flint, or with a reed that was cut lengthwise and sharpened, his slaughter is valid.
הכל שוחטין ולעולם שוחטין ובכל שוחטין חוץ ממגל קציר והמגירה והשינים והציפורן מפני שהם חונקין:
All slaughter [hakkol shoḥatin], and one may always slaughter, and one may slaughter with any item that cuts, except for the serrated side of the harvest sickle, a saw, the teeth of an animal when attached to its jawbone, and a fingernail, because they are serrated and they consequently strangle the animal and do not cut its windpipe and gullet as required.
גמ׳ השוחט דיעבד אין לכתחלה לא בשלמא במגל יד דלמא אתי למעבד באידך גיסא אלא צור וקנה לכתחלה לא ורמינהי בכל שוחטין בין בצור בין בזכוכית בין בקרומית של קנה
GEMARA: The Gemara notes that the language of the mishna, which states: One who slaughters an animal with a hand sickle, with a flint, or with a reed, rather than: One may slaughter, indicates that after the fact, yes, the slaughter is valid, but one may not slaughter with those blades ab initio. The Gemara asks: Granted, one may not slaughter it with a hand sickle, lest he come to perform the slaughter with the other, serrated, side; but as a flint and a reed have no serrated side, is it so that one may not slaughter with those ab initio? And the Gemara raises a contradiction from a baraita: One may slaughter with any item that cuts, whether with a flint, or with glass shards, or with the stalk of a reed.
לא קשיא כאן בתלוש כאן במחובר דאמר רב כהנא השוחט במחובר לקרקע רבי פוסל ור’ חייא מכשיר עד כאן לא קא מכשיר רבי חייא אלא בדיעבד אבל לכתחלה לא
The Gemara answers: This is not difficult. There, where the baraita permits slaughter ab initio, it is referring to slaughter with a flint and a reed when they are detached. Here, where the mishna says that the slaughter is valid only after the fact, it is referring to slaughter with a flint and a reed when they are attached to the ground, as Rav Kahana says: In the case of one who slaughters with a blade that is attached to the ground, Rabbi Yehuda HaNasi deems the slaughter not valid and Rabbi Ḥiyya deems it valid. The Gemara infers: Even Rabbi Ḥiyya deems the slaughter valid only after the fact; but one may not do so ab initio.
במאי אוקימתא כרבי חייא ודיעבד אלא הא דתניא בכל שוחטין בין בתלוש בין במחובר בין שהסכין למעלה וצואר בהמה למטה בין שהסכין למטה וצואר בהמה למעלה מני לא רבי ולא ר’ חייא אי ר’ חייא דיעבד אין לכתחלה לא אי רבי דיעבד נמי לא
In accordance with which opinion did you interpret the mishna? Is it in accordance with the opinion of Rabbi Ḥiyya, and the slaughter is valid after the fact? But if so, with regard to that which is taught in a baraita: One may slaughter with any item that cuts, whether with a blade that is detached from the ground or with a blade that is attached to the ground, whether the knife is above and the neck of the animal is below or the knife is below and the neck of the animal is above; in accordance with whose opinion is it? It is in accordance neither with the opinion of Rabbi Yehuda HaNasi nor with the opinion of Rabbi Ḥiyya. If one would claim that it is in accordance with the opinion of Rabbi Ḥiyya, he says: After the fact, yes, the slaughter is valid, but it is not permitted to slaughter in this manner ab initio. If one would claim that it is in accordance with the opinion of Rabbi Yehuda HaNasi, he says: Even after the fact, the slaughter is not valid.
לעולם רבי חייא ואפילו לכתחלה והאי דקמיפלגי בדיעבד להודיעך כחו דרבי
The Gemara answers: Actually, the baraita is in accordance with the opinion of Rabbi Ḥiyya, and he permits slaughter with these blades even ab initio. And the fact that the opinions of Rabbi Yehuda HaNasi and Rabbi Ḥiyya were formulated such that they disagree concerning the halakha after the fact is to convey to you the far-reaching nature of the opinion of Rabbi Yehuda HaNasi that the slaughter is not valid even after the fact.
ואלא מתניתין דקתני השוחט דיעבד אין לכתחלה לא מני לא רבי ולא רבי חייא אי רבי חייא אפילו לכתחלה אי רבי דיעבד נמי לא
But rather, the mishna here, which teaches: With regard to one who slaughters, after the fact, yes, it is valid, but it is not ab initio, in accordance with whose opinion is it? It is in accordance neither with the opinion of Rabbi Yehuda HaNasi nor with the opinion of Rabbi Ḥiyya. If one would claim that it is in accordance with the opinion of Rabbi Ḥiyya, he says: The slaughter is permitted even ab initio. If one would claim that it is in accordance with the opinion of Rabbi Yehuda HaNasi, he says: Even after the fact, the slaughter is not valid.
לעולם רבי חייא ואפילו לכתחלה ומתניתין דקתני השוחט רבי היא
The Gemara answers: Actually, Rabbi Ḥiyya holds that it is permitted to slaughter with these blades, and even ab initio; and the mishna here, which teaches: One who slaughters, is in accordance with the opinion of Rabbi Yehuda HaNasi.
קשיא דרבי אדרבי לא קשיא כאן במחובר מעיקרו כאן בתלוש ולבסוף חיברו
The Gemara objects: This is difficult, as there is a contradiction between one statement of Rabbi Yehuda HaNasi and another statement of Rabbi Yehuda HaNasi, as in his dispute with Rabbi Ḥiyya he holds that the slaughter is not valid. The Gemara answers: This contradiction is not difficult. There, in his dispute with Rabbi Ḥiyya, Rabbi Yehuda HaNasi holds that slaughter is not valid in a case where the blade was attached from the outset; here, in the mishna, Rabbi Yehuda HaNasi deems the slaughter valid after the fact in a case where the blade was detached and ultimately he reattached it.
ומנא תימרא דשני לן בין מחובר מעיקרו לתלוש ולבסוף חיברו דתניא השוחט במוכני שחיטתו כשרה במחובר לקרקע שחיטתו כשרה נעץ סכין בכותל ושחט בה שחיטתו כשרה היה צור יוצא מן הכותל או קנה עולה מאליו ושחט בו שחיטתו פסולה
The Gemara asks: And from where do you say that there is a difference for us between a blade that was attached from the outset and a blade that was detached and ultimately he reattached it? As it is taught in a baraita: With regard to one who slaughters with a mechanism [bemukhni] of a wheel with a knife attached to it, his slaughter is valid; with an item that is attached to the ground, his slaughter is valid; if one embedded a knife in a wall and slaughtered with it, his slaughter is valid. If there was a flint emerging from a wall or a reed arising from the ground on its own and he slaughtered with it, his slaughter is not valid.
