The mishna recommends that a husband should ask his wife before Shabbat starts if she tithed the produce and set up an eiruv and if so, she should light the candles. What things cannot be done once the time of twilight (bein hashmashot) has arrived? What things can still be done during this time period? The gemara resolves a potential contradiction in the mishna reagarding eiruv. What is hatmana? What type is forbidden even before Shabbat and what type is permitted even during twilight. Why? Twilight is considered a time that is maybe day, maybe night or maybe both. What is the tannatic debate regarding when exactly is twilight? What is the relevance for this time of doubt regarding impurity of a zav? Raba and Rav Yosef have a disagreement about how to understand the time of twilight according to Rabbi Yehuda, as his words seem to include contradictory statements and each resolves it in a different way. This disagreement is consistent with their opinion regarding the length of time that twilight spans.

Shabbat 34
וְאִית לְהוּ צַעֲרָא לְכֹהֲנִים לְאַקּוֹפֵי. אֲמַר: אִיכָּא אִינִישׁ דְּיָדַע דְּאִיתַּחְזַק הָכָא טָהֳרָה? אֲמַר לֵיהּ הָהוּא סָבָא: כָּאן קִיצֵּץ בֶּן זַכַּאי תּוּרְמְסֵי תְּרוּמָה. עֲבַד אִיהוּ נָמֵי הָכִי, כָּל הֵיכָא דַּהֲוָה קְשֵׁי — טַהֲרֵיהּ, וְכָל הֵיכָא דַּהֲוָה רְפֵי — צַיְּינֵיהּ.
and the priests are troubled by being forced to circumvent it, as it is prohibited for them to become ritually impure from contact with a corpse. There was suspicion, but no certainty, that a corpse was buried there. Therefore, they were unable to definitively determine its status. Rabbi Shimon said: Is there a person who knows that there was a presumption of ritual purity here? Is there anyone who remembers a time when this place was not considered ritually impure, or that at least part of it was considered to be ritually pure? An Elder said to him: Here ben Zakkai planted and cut the teruma of lupines. In this marketplace Rabbi Yoḥanan ben Zakkai, who himself was a priest, once planted lupines that were given to him as teruma. On that basis, the conclusion can be drawn that it was definitely ritually pure. Rabbi Shimon, like Jacob, also did so and took steps to improve the city and examined the ground (Tosafot). Everywhere that the ground was hard, he pronounced it ritually pure as there was certainly no corpse there, and every place that the ground was soft, he marked it indicating that perhaps a corpse was buried there. In that way, he purified the marketplace so that even priests could walk through it.
אֲמַר הָהוּא סָבָא: טִיהֵר בֶּן יוֹחַי בֵּית הַקְּבָרוֹת! אֲמַר לֵיהּ: אִילְמָלֵי לֹא הָיִיתָ עִמָּנוּ, וַאֲפִילּוּ הָיִיתָ עִמָּנוּ, וְלֹא נִמְנֵיתָ עִמָּנוּ — יָפֶה אַתָּה אוֹמֵר. עַכְשָׁיו שֶׁהָיִיתָ עִמָּנוּ, וְנִמְנֵיתָ עִמָּנוּ, יֹאמְרוּ: זוֹנוֹת מְפַרְכְּסוֹת זוֹ אֶת זוֹ, תַּלְמִידֵי חֲכָמִים לֹא כָּל שֶׁכֵּן?! יְהַב בֵּיהּ עֵינֵיהּ וְנָח נַפְשֵׁיהּ. נְפַק לְשׁוּקָא חַזְיֵיהּ לִיהוּדָה בֶּן גֵּרִים. אֲמַר: עֲדַיִין יֵשׁ לְזֶה בָּעוֹלָם? נָתַן בּוֹ עֵינָיו וְעָשָׂהוּ גַּל שֶׁל עֲצָמוֹת.
A certain Elder said in ridicule and surprise: Ben Yoḥai purified the cemetery. Rabbi Shimon got angry and said to him: Had you not been with us, and even had you been with us and were not counted with us in rendering this ruling, what you say is fine. You could have said that you were unaware of my intention or that you did not agree or participate in this decision. Now that you were with us and were counted with us in rendering this ruling, you will cause people to say that Sages are unwilling to cooperate with one another. They will say: If competing prostitutes still apply makeup to each other to help one another look beautiful, all the more so that Torah scholars should cooperate with each other. He directed his eyes toward him and the Elder died. Rabbi Shimon went out to the marketplace and he saw Yehuda, son of converts, who was the cause of this entire incident. Rabbi Shimon, said: This one still has a place in the world? He directed his eyes toward him and turned him into a pile of bones.
מַתְנִי׳ שְׁלֹשָׁה דְּבָרִים צָרִיךְ אָדָם לוֹמַר בְּתוֹךְ בֵּיתוֹ עֶרֶב שַׁבָּת עִם חֲשֵׁכָה: עִשַּׂרְתֶּם? עֵרַבְתֶּם? — הַדְלִיקוּ אֶת הַנֵּר. סָפֵק חֲשֵׁכָה סָפֵק אֵינוֹ חֲשֵׁכָה — אֵין מְעַשְּׂרִין אֶת הַוַּדַּאי, וְאֵין מַטְבִּילִין אֶת הַכֵּלִים, וְאֵין מַדְלִיקִין אֶת הַנֵּרוֹת. אֲבָל מְעַשְּׂרִין אֶת הַדְּמַאי, וּמְעָרְבִין, וְטוֹמְנִין אֶת הַחַמִּין.
MISHNA: There are three things a person must say in his home on Shabbat eve at nightfall and not before. The mishna elaborates: He should ask the members of his household, have you tithed the crop that required tithing? Have you placed the eiruv for joining the courtyards and joining the Shabbat borders? If you have done so, light the lamp in honor of Shabbat. The Sages stated a principle: If the time arrives on Friday when there is uncertainty whether it is nightfall and uncertainty whether it is not yet nightfall, one may not tithe the crop that has definitely not been tithed, and one may not immerse ritually impure vessels in a ritual bath to render them ritually pure, and one may not light the Shabbat lights. However, one may tithe demai, doubtfully tithed produce, which must be tithed due to mere suspicion. And one may place an eiruv and insulate the hot water to be used on Shabbat.
גְּמָ׳ מְנָא הָנֵי מִילֵּי? אָמַר רַבִּי יְהוֹשֻׁעַ בֶּן לֵוִי: אָמַר קְרָא: ״וְיָדַעְתָּ כִּי שָׁלוֹם אָהֳלֶךָ וּפָקַדְתָּ נָוְךָ וְלֹא תֶחֱטָא״. אָמַר רַבָּה בַּר רַב הוּנָא: אַף עַל גַּב דַּאֲמוּר רַבָּנַן שְׁלֹשָׁה דְּבָרִים צָרִיךְ אָדָם לוֹמַר וְכוּ׳ — צְרִיךְ לְמֵימְרִינֵהוּ בְּנִיחוּתָא, כִּי הֵיכִי דְּלִיקַבְּלִינְהוּ מִינֵּיהּ. אָמַר רַב אָשֵׁי: אֲנָא לָא שְׁמִיעַ לִי הָא דְּרַבָּה בַּר רַב הוּנָא, וְקַיֵּימְתַּהּ מִסְּבָרָא.
GEMARA: The Gemara attempts to clarify: From where are these matters, that one must ask these questions in his home at nightfall of Shabbat, derived? Rabbi Yehoshua ben Levi said: As the verse said: “And you shall know that your tent is in peace; and you shall visit your habitation, and shall not sin” (Job 5:24). From here it is derived that one should visit his habitation, i.e., ask in his home, so that he will not come to sin. Rabba bar Rav Huna said: Although the Sages said that there are three things a person should, indeed he is required to, say in his home on Shabbat eve at nightfall, one must say them calmly so that the members of his household will accept them from him. If he says them harshly, his family members may mislead him and cause him to sin. Rav Ashi said: I did not hear this halakha of Rabba bar Rav Huna, but I fulfilled it based on my own reasoning.
הָא גוּפָא קַשְׁיָא: אָמְרַתְּ שְׁלֹשָׁה דְּבָרִים צָרִיךְ אָדָם לוֹמַר בְּתוֹךְ בֵּיתוֹ עֶרֶב שַׁבָּת עִם חֲשֵׁכָה. עִם חֲשֵׁכָה — אִין, סָפֵק חֲשֵׁכָה סָפֵק אֵינוֹ חֲשֵׁכָה — לָא. וַהֲדַר תָּנֵי: סָפֵק חֲשֵׁכָה סָפֵק אֵינוֹ חֲשֵׁכָה — מְעָרֵב.
The Gemara asks: This mishna itself is difficult, as it contains an internal contradiction. On the one hand, you stated initially that there are three things a person must say in his home before Shabbat at nightfall, and this means: At nightfall, i.e., before nightfall, yes, he should say those things; when there is uncertainty whether it is nightfall and uncertainty whether it is not yet nightfall, no, he should not say them. Even if one were to ask then, it is no longer permitted to correct these matters. And then it taught: When there is uncertainty whether it is nightfall and uncertainty whether it is not yet nightfall, one may place an eiruv. One may correct the situation even then. Why did the mishna restrict asking these questions to an earlier time?
סִימָן: בְּגוּפְיָא זִימְרָא צִיפְּרָא בְּחַבְלָא דְמֵילָתָא.
Incidentally, prior to answering this question, the Gemara lists all of the other halakhot in tractate Shabbat stated by the Sage who answers the question, with the mnemonic: Self, pruning, bird, cord, silk.
אָמַר רַבִּי אַבָּא אָמַר רַב חִיָּיא בַּר אָשֵׁי אָמַר רַב: לָא קַשְׁיָא, כָּאן בְּעֵירוּבֵי תְּחוּמִין, כָּאן בְּעֵירוּבֵי חֲצֵרוֹת.
Rabbi Abba said that Rabbi Ḥiyya bar Ashi said that Rav said: This is not difficult and there is no contradiction here. Here, at the beginning of the mishna, where it indicates that the eiruv can only be placed while it is still day, it is referring to the joining of Shabbat boundaries, which is based on a Torah law. Therefore, one must place this eiruv while it is definitely day. And here, where the mishna said that it is permitted even when it is uncertain whether or not it is already nighttime, it is referring to the joining of courtyards, which is more lenient and based merely on a stringency.
וְאָמַר רָבָא: אָמְרוּ לוֹ שְׁנַיִם צֵא וְעָרֵב עָלֵינוּ, לְאֶחָד עֵירַב עָלָיו מִבְּעוֹד יוֹם, וּלְאֶחָד עֵירַב עָלָיו בֵּין הַשְּׁמָשׁוֹת — זֶה שֶׁעֵירַב עָלָיו מִבְּעוֹד יוֹם נֶאֱכַל עֵירוּבוֹ בֵּין הַשְּׁמָשׁוֹת, וְזֶה שֶׁעֵירַב עָלָיו בֵּין הַשְּׁמָשׁוֹת נֶאֱכַל עֵירוּבוֹ מִשֶּׁחָשֵׁכָה. שְׁנֵיהֶם קָנוּ עֵירוּב.
In connection to this, the Gemara cites the halakha that Rava said in order to emphasize the rabbinic aspect of the halakhot of eiruv: One to whom two people said: Go and place an eiruv, a joining of courtyards (Rabbeinu Ḥananel), for us. For one of them he placed an eiruv while it was still day, and for one he placed an eiruv at twilight, when it is uncertain whether it is day or night. The one for whom he placed an eiruv while it was still day had his eiruv eaten during twilight, and the one for whom he placed an eiruv during twilight had his eiruv eaten after nightfall. The principle is as follows: Whether or not an eiruv takes effect is determined at the moment that Shabbat begins. If one placed the eiruv beforehand, and it remains intact at the moment Shabbat begins, the eiruv is in effect. However, if the eiruv that was placed at the appropriate time was eaten during twilight, it is problematic. Twilight is a period of uncertainty. There is uncertainty whether it is day, and consequently the eiruv was not in place at the moment that Shabbat began, or whether it is night, and it was in place. In the latter case, there is still uncertainty as to whether or not the eiruv was in place prior to Shabbat, so that it could take effect at all. In that case, Rava ruled that both of them acquired the eiruv.
מָה נַפְשָׁךְ. אִי בֵּין הַשְּׁמָשׁוֹת יְמָמָא הוּא — בָּתְרָא לִיקְנֵי קַמָּא לָא לִיקְנֵי. וְאִי בֵּין הַשְּׁמָשׁוֹת לֵילְיָא הוּא — קַמָּא לִיקְנֵי בָּתְרָא לָא לִיקְנֵי! בֵּין הַשְּׁמָשׁוֹת סְפֵקָא הוּא, וּסְפֵקָא דְרַבָּנַן לְקוּלָּא.
The Gemara is surprised by this: Whichever way you look at it, this ruling is difficult. If the twilight period is considered day, let the latter one acquire his eiruv, but let the first one not acquire his because his eiruv was eaten while it was still day. And if the twilight period is night, let the first one acquire his eiruv, but let the latter one not acquire his eiruv because his was not placed before Shabbat. In any event, it is impossible for the eiruv in both of these cases to be valid. The Gemara answers this according to Rava’s position: The status of twilight is uncertain, as it is unknown whether it is day, or night, or both, and uncertainty in the case of a rabbinic ordinance is ruled leniently. Therefore, in both cases the eiruv is acquired.
[אָמַר] רָבָא: מִפְּנֵי מָה אָמְרוּ אֵין טוֹמְנִין בְּדָבָר שֶׁאֵינוֹ מוֹסִיף הֶבֶל מִשֶּׁחָשֵׁכָה? — גְּזֵרָה שֶׁמָּא יַרְתִּיחַ. אֲמַר לֵיהּ אַבָּיֵי: אִי הָכִי, בֵּין הַשְּׁמָשׁוֹת נָמֵי נִיגְזַר?! אֲמַר לֵיהּ: סְתָם קְדֵירוֹת רוֹתְחוֹת הֵן.
And Rava said: Why did they say that one may not insulate hot water even in something that does not add heat, but only retains the pre-existing heat, from nightfall on Friday? It is a decree lest one come to boil the pot on Shabbat. Abaye said to him: If so, if it is due to concern that one may boil it, then during twilight we should also issue a decree and prohibit insulating in something that does not add heat. Rava said to him: During twilight, there is no reason to be concerned because at that time most pots are boiling, as they have just been taken off of the fire. Later at night the pots cool down and it is conceivable that one may come to boil them in order to restore the heat.
וְאָמַר רָבָא:
And Rava said:
מִפְּנֵי מָה אָמְרוּ אֵין טוֹמְנִין בְּדָבָר הַמּוֹסִיף הֶבֶל וַאֲפִילּוּ מִבְּעוֹד יוֹם? — גְּזֵירָה שֶׁמָּא יַטְמִין בְּרֶמֶץ שֶׁיֵּשׁ בָּהּ גַּחֶלֶת. אֲמַר לֵיהּ אַבָּיֵי: וְיַטְמִין? גְּזֵירָה שֶׁמָּא יְחַתֶּה בַּגֶּחָלִים.
Why did the Sages say that one may not insulate hot water for Shabbat in something that adds heat, even while it is still day? It is a decree lest one come to cover it in hot ashes that contain a glowing ember. People may not differentiate between addition of heat by means of hot ashes and other additions of heat. Abaye said to him: Let him insulate it with hot ashes, what is the problem? Rava answered him: It is a decree lest one come to stoke the coals in order to make them burn on Shabbat and thereby violate a Torah prohibition.
תָּנוּ רַבָּנַן: בֵּין הַשְּׁמָשׁוֹת סָפֵק מִן הַיּוֹם וּמִן הַלַּיְלָה, סָפֵק כּוּלּוֹ מִן הַיּוֹם, סָפֵק כּוּלּוֹ מִן הַלַּיְלָה — מְטִילִין אוֹתוֹ לְחוֹמֶר שְׁנֵי יָמִים.
The Sages taught a baraita which discusses the range of problems that arise with regard to the twilight period. Twilight is a period of uncertainty. It is uncertain whether it consists of both day and night, it is uncertain whether it is completely day, and it is uncertain whether it is completely night. Therefore, the Sages impose the stringencies of both days upon it. If there is a stringency that applies on either of the days, one is obligated to adhere to it during the twilight period.
וְאֵיזֶהוּ בֵּין הַשְּׁמָשׁוֹת? — מִשֶּׁתִּשְׁקַע הַחַמָּה כָּל זְמַן שֶׁפְּנֵי מִזְרָח מַאֲדִימִין. הִכְסִיף הַתַּחְתּוֹן וְלֹא הִכְסִיף הָעֶלְיוֹן — בֵּין הַשְּׁמָשׁוֹת. הִכְסִיף הָעֶלְיוֹן וְהִשְׁוָה לַתַּחְתּוֹן — זֶהוּ לַיְלָה, דִּבְרֵי רַבִּי יְהוּדָה. רַבִּי נְחֶמְיָה אוֹמֵר: כְּדֵי שֶׁיְּהַלֵּךְ אָדָם מִשֶּׁתִּשְׁקַע הַחַמָּה חֲצִי מִיל. רַבִּי יוֹסִי אוֹמֵר: בֵּין הַשְּׁמָשׁוֹת כְּהֶרֶף עַיִן, זֶה נִכְנָס וְזֶה יוֹצֵא, וְאִי אֶפְשָׁר לַעֲמוֹד עָלָיו.
Nevertheless, the definition of twilight is uncertain. And what is twilight? From when the sun sets, as long as the eastern face of the sky is reddened by the light of the sun. If the lower segment of the sky has lost its color, and the upper segment has not yet lost its color, that is the twilight period. If the upper segment has lost its color, and its color equals that of the lower one, it is night; this is the statement of Rabbi Yehuda. Rabbi Neḥemya says: The duration of the twilight period is the time it takes for a person to walk half a mil after the sun sets. Rabbi Yosei says: Twilight does not last for a quantifiable period of time; rather, it is like the blink of an eye: This, night, enters and that, day, leaves, and it is impossible to calculate it due to its brevity.
אָמַר מָר: מְטִילִין אוֹתוֹ לְחוֹמֶר שְׁנֵי יָמִים. לְמַאי הִלְכְתָא? אָמַר רַב הוּנָא בְּרֵיהּ דְּרַב יְהוֹשֻׁעַ לְעִנְיַן טוּמְאָה, כְּדִתְנַן: רָאָה שְׁנֵי יָמִים בֵּין הַשְּׁמָשׁוֹת — סָפֵק לַטּוּמְאָה וְלַקׇּרְבָּן. רָאָה יוֹם אֶחָד בֵּין הַשְּׁמָשׁוֹת — סָפֵק לַטּוּמְאָה.
It was taught in the baraita that the Master said: The Sages impose the stringencies of both days upon twilight. The Gemara asks: With regard to what halakha was this stated? Rav Huna, son of Rav Yehoshua, said: With regard to the matter of ritual impurity, as we learned in a mishna: With regard to a zav who saw an emission for two consecutive days during twilight, it is unclear whether it should be considered as if he only saw the emission for a single day, as perhaps twilight of the first day was part of the following day, and twilight of the second day was part of the previous day; or, whether it should be considered as two days, attributing each twilight to either the previous or the following day; or, whether it should be considered three days, as it is possible to view the twilight period as two days. By Torah law, a zav who saw two emissions is ritually impure, and all of the stringencies of a zav apply to him. If he sees a third emission, he is liable to bring an offering as part of his purification ritual. Therefore, this zav, with regard to whom there is uncertainty whether he saw emissions for one day, two days, or three days, has uncertain status with regard to both ritual impurity and to sacrifice. If he saw an emission one day during twilight, he has uncertain status with regard to ritual impurity because it may be considered two days.

The Gemara comments on the baraita cited by the Gemara. This baraita is itself difficult, self-contradictory. Initially you said, what is twilight? From when the sun sets, as long as the eastern face of the sky is reddened by the light of the sun. By inference, if the bottom segment lost its color, and the upper one has not lost its color, it is night. And then the baraita taught: If the lower segment of the sky has lost its color, and the upper segment has not yet lost its color, that is the twilight period. There is an apparent internal contradiction in the baraita. Rabba said that Rav Yehuda said that Shmuel said: In order to resolve the contradiction, unify the two statements and teach it as follows: What is twilight? From when the sun sets, as long as the eastern face of the sky is reddened by the light of the sun. If the lower segment of the sky has lost its color and the upper segment has not yet lost its color, that is also the twilight period. Only if the upper segment lost its color, and it equals that of the lower one, is it night. And Rav Yosef said that Rav Yehuda said that Shmuel said otherwise: From when the sun sets, as long as the eastern face of the sky is reddened by the light of the sun, it is day. If the lower segment of the sky has lost its color, and the upper segment has not yet lost its color, that is the twilight period. If the upper segment lost its color and it equals that of the lower one, it is night.
וְאָזְדוּ לְטַעְמַיְיהוּ, דְּאִיתְּמַר: שִׁיעוּר בֵּין הַשְּׁמָשׁוֹת בְּכַמָּה? אָמַר רַבָּה אָמַר רַב יְהוּדָה אָמַר שְׁמוּאֵל: שְׁלֹשָׁה חֶלְקֵי מִיל. מַאי שְׁלֹשָׁה חֶלְקֵי מִיל? אִילֵימָא תְּלָתָא פַּלְגֵי מִילָא — נֵימָא מִיל וּמֶחֱצָה. אֶלָּא תְּלָתָא תִּילְתֵי מִילָא — נֵימָא מִיל. אֶלָּא: תְּלָתָא רִיבְעֵי מִילָא. וְרַב יוֹסֵף אָמַר רַב יְהוּדָה אָמַר שְׁמוּאֵל: שְׁנֵי חֶלְקֵי מִיל. מַאי שְׁנֵי חֶלְקֵי מִיל? אִילֵימָא תְּרֵי פַּלְגֵי מִילָא — לֵימָא מִיל. וְאֶלָּא תְּרֵי רִבְעֵי מִילָא — לֵימָא חֲצִי מִיל. אֶלָּא
And the Gemara remarks: In this dispute over the precise definition of twilight both Rabba and Rav Yosef follow their line of reasoning stated elsewhere. As it was stated: What is the measure of the duration of twilight? Rabba said that Rav Yehuda said that Shmuel said: The time it takes to walk three parts of a mil. The Gemara asks: What is the meaning of three parts of a mil? If you say that it refers to three halves of a mil, let him say a mil and a half. Rather, if you say that it means three-thirds of a mil, let him simply say one mil. Rather, it means three-quarters of a mil. And Rav Yosef said that Rav Yehuda said that Shmuel said: The duration of twilight is two parts of a mil. Again the Gemara asks: What is the meaning of two parts of a mil? If you say that it means two halves of a mil, let him simply say one mil. Rather, if you say that it means two-quarters of a mil, let him say instead: Half of a mil. Rather,

The Hadran Women’s Tapestry
Meet the diverse women learning Gemara at Hadran and hear their stories.
Palo Alto, CA, United States
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!
Modi’in, Israel
I started learning Daf Yomi inspired by תָּפַסְתָּ מְרוּבֶּה לֹא תָּפַסְתָּ, תָּפַסְתָּ מוּעָט תָּפַסְתָּ. I thought I’d start the first page, and then see. I was swept up into the enthusiasm of the Hadran Siyum, and from there the momentum kept building. Rabbanit Michelle’s shiur gives me an anchor, a connection to an incredible virtual community, and an energy to face whatever the day brings.
בית שמש, Israel
I began learning the daf in January 2022. I initially “flew under the radar,” sharing my journey with my husband and a few close friends. I was apprehensive – who, me? Gemara? Now, 2 years in, I feel changed. The rigor of a daily commitment frames my days. The intellectual engagement enhances my knowledge. And the virtual community of learners has become a new family, weaving a glorious tapestry.
Far Rockaway, United States
It happened without intent (so am I yotzei?!) – I watched the women’s siyum live and was so moved by it that the next morning, I tuned in to Rabbanit Michelle’s shiur, and here I am, still learning every day, over 2 years later. Some days it all goes over my head, but others I grasp onto an idea or a story, and I ‘get it’ and that’s the best feeling in the world. So proud to be a Hadran learner.
Zichron Yaakov, Israel
I have joined the community of daf yomi learners at the start of this cycle. I have studied in different ways – by reading the page, translating the page, attending a local shiur and listening to Rabbanit Farber’s podcasts, depending on circumstances and where I was at the time. The reactions have been positive throughout – with no exception!
Guildford, 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!
Minnesota, United States
I started learning daf in January, 2020, being inspired by watching the Siyyum Hashas in Binyanei Haumah. I wasn’t sure I would be able to keep up with the task. When I went to school, Gemara was not an option. Fast forward to March, 2022, and each day starts with the daf. The challenge is now learning the intricacies of delving into the actual learning. Hadran community, thank you!

When we heard that R. Michelle was starting daf yomi, my 11-year-old suggested that I go. Little did she know that she would lose me every morning from then on. I remember standing at the Farbers’ door, almost too shy to enter. After that first class, I said that I would come the next day but couldn’t commit to more. A decade later, I still look forward to learning from R. Michelle every morning.
Ra’anana, Israel
I started learning on January 5, 2020. When I complete the 7+ year cycle I will be 70 years old. I had been intimidated by those who said that I needed to study Talmud in a traditional way with a chevruta, but I decided the learning was more important to me than the method. Thankful for Daf Yomi for Women helping me catch up when I fall behind, and also being able to celebrate with each Siyum!
Bakersfield, United States
The first month I learned Daf Yomi by myself in secret, because I wasn’t sure how my husband would react, but after the siyyum on Masechet Brachot I discovered Hadran and now sometimes my husband listens to the daf with me. He and I also learn mishnayot together and are constantly finding connections between the different masechtot.

I started learning Daf in Jan 2020 with Brachot b/c I had never seen the Jewish people united around something so positive, and I wanted to be a part of it. Also, I wanted to broaden my background in Torah Shebal Peh- Maayanot gave me a great gemara education, but I knew that I could hold a conversation in most parts of tanach but almost no TSB. I’m so thankful for Daf and have gained immensely.

I am a Reform rabbi and took Talmud courses in rabbinical school, but I knew there was so much more to learn. It felt inauthentic to serve as a rabbi without having read the entire Talmud, so when the opportunity arose to start Daf Yomi in 2020, I dove in! Thanks to Hadran, Daf Yomi has enriched my understanding of rabbinic Judaism and deepened my love of Jewish text & tradition. Todah rabbah!

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.

In January 2020 on a Shabbaton to Baltimore I heard about the new cycle of Daf Yomi after the siyum celebration in NYC stadium. I started to read “ a daily dose of Talmud “ and really enjoyed it . It led me to google “ do Orthodox women study Talmud? “ and found HADRAN! Since then I listen to the podcast every morning, participate in classes and siyum. I love to learn, this is amazing! Thank you

I started the daf at the beginning of this cycle in January 2020. My husband, my children, grandchildren and siblings have been very supportive. As someone who learned and taught Tanach and mefarshim for many years, it has been an amazing adventure to complete the six sedarim of Mishnah, and now to study Talmud on a daily basis along with Rabbanit Michelle and the wonderful women of Hadran.

I started learning Gemara at the Yeshivah of Flatbush. And I resumed ‘ברוך ה decades later with Rabbanit Michele at Hadran. I started from Brachot and have had an exciting, rewarding experience throughout seder Moed!

Shabbat 34
וְאִית לְהוּ צַעֲרָא לְכֹהֲנִים לְאַקּוֹפֵי. אֲמַר: אִיכָּא אִינִישׁ דְּיָדַע דְּאִיתַּחְזַק הָכָא טָהֳרָה? אֲמַר לֵיהּ הָהוּא סָבָא: כָּאן קִיצֵּץ בֶּן זַכַּאי תּוּרְמְסֵי תְּרוּמָה. עֲבַד אִיהוּ נָמֵי הָכִי, כָּל הֵיכָא דַּהֲוָה קְשֵׁי — טַהֲרֵיהּ, וְכָל הֵיכָא דַּהֲוָה רְפֵי — צַיְּינֵיהּ.
and the priests are troubled by being forced to circumvent it, as it is prohibited for them to become ritually impure from contact with a corpse. There was suspicion, but no certainty, that a corpse was buried there. Therefore, they were unable to definitively determine its status. Rabbi Shimon said: Is there a person who knows that there was a presumption of ritual purity here? Is there anyone who remembers a time when this place was not considered ritually impure, or that at least part of it was considered to be ritually pure? An Elder said to him: Here ben Zakkai planted and cut the teruma of lupines. In this marketplace Rabbi Yoḥanan ben Zakkai, who himself was a priest, once planted lupines that were given to him as teruma. On that basis, the conclusion can be drawn that it was definitely ritually pure. Rabbi Shimon, like Jacob, also did so and took steps to improve the city and examined the ground (Tosafot). Everywhere that the ground was hard, he pronounced it ritually pure as there was certainly no corpse there, and every place that the ground was soft, he marked it indicating that perhaps a corpse was buried there. In that way, he purified the marketplace so that even priests could walk through it.
אֲמַר הָהוּא סָבָא: טִיהֵר בֶּן יוֹחַי בֵּית הַקְּבָרוֹת! אֲמַר לֵיהּ: אִילְמָלֵי לֹא הָיִיתָ עִמָּנוּ, וַאֲפִילּוּ הָיִיתָ עִמָּנוּ, וְלֹא נִמְנֵיתָ עִמָּנוּ — יָפֶה אַתָּה אוֹמֵר. עַכְשָׁיו שֶׁהָיִיתָ עִמָּנוּ, וְנִמְנֵיתָ עִמָּנוּ, יֹאמְרוּ: זוֹנוֹת מְפַרְכְּסוֹת זוֹ אֶת זוֹ, תַּלְמִידֵי חֲכָמִים לֹא כָּל שֶׁכֵּן?! יְהַב בֵּיהּ עֵינֵיהּ וְנָח נַפְשֵׁיהּ. נְפַק לְשׁוּקָא חַזְיֵיהּ לִיהוּדָה בֶּן גֵּרִים. אֲמַר: עֲדַיִין יֵשׁ לְזֶה בָּעוֹלָם? נָתַן בּוֹ עֵינָיו וְעָשָׂהוּ גַּל שֶׁל עֲצָמוֹת.
A certain Elder said in ridicule and surprise: Ben Yoḥai purified the cemetery. Rabbi Shimon got angry and said to him: Had you not been with us, and even had you been with us and were not counted with us in rendering this ruling, what you say is fine. You could have said that you were unaware of my intention or that you did not agree or participate in this decision. Now that you were with us and were counted with us in rendering this ruling, you will cause people to say that Sages are unwilling to cooperate with one another. They will say: If competing prostitutes still apply makeup to each other to help one another look beautiful, all the more so that Torah scholars should cooperate with each other. He directed his eyes toward him and the Elder died. Rabbi Shimon went out to the marketplace and he saw Yehuda, son of converts, who was the cause of this entire incident. Rabbi Shimon, said: This one still has a place in the world? He directed his eyes toward him and turned him into a pile of bones.
מַתְנִי׳ שְׁלֹשָׁה דְּבָרִים צָרִיךְ אָדָם לוֹמַר בְּתוֹךְ בֵּיתוֹ עֶרֶב שַׁבָּת עִם חֲשֵׁכָה: עִשַּׂרְתֶּם? עֵרַבְתֶּם? — הַדְלִיקוּ אֶת הַנֵּר. סָפֵק חֲשֵׁכָה סָפֵק אֵינוֹ חֲשֵׁכָה — אֵין מְעַשְּׂרִין אֶת הַוַּדַּאי, וְאֵין מַטְבִּילִין אֶת הַכֵּלִים, וְאֵין מַדְלִיקִין אֶת הַנֵּרוֹת. אֲבָל מְעַשְּׂרִין אֶת הַדְּמַאי, וּמְעָרְבִין, וְטוֹמְנִין אֶת הַחַמִּין.
MISHNA: There are three things a person must say in his home on Shabbat eve at nightfall and not before. The mishna elaborates: He should ask the members of his household, have you tithed the crop that required tithing? Have you placed the eiruv for joining the courtyards and joining the Shabbat borders? If you have done so, light the lamp in honor of Shabbat. The Sages stated a principle: If the time arrives on Friday when there is uncertainty whether it is nightfall and uncertainty whether it is not yet nightfall, one may not tithe the crop that has definitely not been tithed, and one may not immerse ritually impure vessels in a ritual bath to render them ritually pure, and one may not light the Shabbat lights. However, one may tithe demai, doubtfully tithed produce, which must be tithed due to mere suspicion. And one may place an eiruv and insulate the hot water to be used on Shabbat.
גְּמָ׳ מְנָא הָנֵי מִילֵּי? אָמַר רַבִּי יְהוֹשֻׁעַ בֶּן לֵוִי: אָמַר קְרָא: ״וְיָדַעְתָּ כִּי שָׁלוֹם אָהֳלֶךָ וּפָקַדְתָּ נָוְךָ וְלֹא תֶחֱטָא״. אָמַר רַבָּה בַּר רַב הוּנָא: אַף עַל גַּב דַּאֲמוּר רַבָּנַן שְׁלֹשָׁה דְּבָרִים צָרִיךְ אָדָם לוֹמַר וְכוּ׳ — צְרִיךְ לְמֵימְרִינֵהוּ בְּנִיחוּתָא, כִּי הֵיכִי דְּלִיקַבְּלִינְהוּ מִינֵּיהּ. אָמַר רַב אָשֵׁי: אֲנָא לָא שְׁמִיעַ לִי הָא דְּרַבָּה בַּר רַב הוּנָא, וְקַיֵּימְתַּהּ מִסְּבָרָא.
GEMARA: The Gemara attempts to clarify: From where are these matters, that one must ask these questions in his home at nightfall of Shabbat, derived? Rabbi Yehoshua ben Levi said: As the verse said: “And you shall know that your tent is in peace; and you shall visit your habitation, and shall not sin” (Job 5:24). From here it is derived that one should visit his habitation, i.e., ask in his home, so that he will not come to sin. Rabba bar Rav Huna said: Although the Sages said that there are three things a person should, indeed he is required to, say in his home on Shabbat eve at nightfall, one must say them calmly so that the members of his household will accept them from him. If he says them harshly, his family members may mislead him and cause him to sin. Rav Ashi said: I did not hear this halakha of Rabba bar Rav Huna, but I fulfilled it based on my own reasoning.
הָא גוּפָא קַשְׁיָא: אָמְרַתְּ שְׁלֹשָׁה דְּבָרִים צָרִיךְ אָדָם לוֹמַר בְּתוֹךְ בֵּיתוֹ עֶרֶב שַׁבָּת עִם חֲשֵׁכָה. עִם חֲשֵׁכָה — אִין, סָפֵק חֲשֵׁכָה סָפֵק אֵינוֹ חֲשֵׁכָה — לָא. וַהֲדַר תָּנֵי: סָפֵק חֲשֵׁכָה סָפֵק אֵינוֹ חֲשֵׁכָה — מְעָרֵב.
The Gemara asks: This mishna itself is difficult, as it contains an internal contradiction. On the one hand, you stated initially that there are three things a person must say in his home before Shabbat at nightfall, and this means: At nightfall, i.e., before nightfall, yes, he should say those things; when there is uncertainty whether it is nightfall and uncertainty whether it is not yet nightfall, no, he should not say them. Even if one were to ask then, it is no longer permitted to correct these matters. And then it taught: When there is uncertainty whether it is nightfall and uncertainty whether it is not yet nightfall, one may place an eiruv. One may correct the situation even then. Why did the mishna restrict asking these questions to an earlier time?
סִימָן: בְּגוּפְיָא זִימְרָא צִיפְּרָא בְּחַבְלָא דְמֵילָתָא.
Incidentally, prior to answering this question, the Gemara lists all of the other halakhot in tractate Shabbat stated by the Sage who answers the question, with the mnemonic: Self, pruning, bird, cord, silk.
אָמַר רַבִּי אַבָּא אָמַר רַב חִיָּיא בַּר אָשֵׁי אָמַר רַב: לָא קַשְׁיָא, כָּאן בְּעֵירוּבֵי תְּחוּמִין, כָּאן בְּעֵירוּבֵי חֲצֵרוֹת.
Rabbi Abba said that Rabbi Ḥiyya bar Ashi said that Rav said: This is not difficult and there is no contradiction here. Here, at the beginning of the mishna, where it indicates that the eiruv can only be placed while it is still day, it is referring to the joining of Shabbat boundaries, which is based on a Torah law. Therefore, one must place this eiruv while it is definitely day. And here, where the mishna said that it is permitted even when it is uncertain whether or not it is already nighttime, it is referring to the joining of courtyards, which is more lenient and based merely on a stringency.
וְאָמַר רָבָא: אָמְרוּ לוֹ שְׁנַיִם צֵא וְעָרֵב עָלֵינוּ, לְאֶחָד עֵירַב עָלָיו מִבְּעוֹד יוֹם, וּלְאֶחָד עֵירַב עָלָיו בֵּין הַשְּׁמָשׁוֹת — זֶה שֶׁעֵירַב עָלָיו מִבְּעוֹד יוֹם נֶאֱכַל עֵירוּבוֹ בֵּין הַשְּׁמָשׁוֹת, וְזֶה שֶׁעֵירַב עָלָיו בֵּין הַשְּׁמָשׁוֹת נֶאֱכַל עֵירוּבוֹ מִשֶּׁחָשֵׁכָה. שְׁנֵיהֶם קָנוּ עֵירוּב.
In connection to this, the Gemara cites the halakha that Rava said in order to emphasize the rabbinic aspect of the halakhot of eiruv: One to whom two people said: Go and place an eiruv, a joining of courtyards (Rabbeinu Ḥananel), for us. For one of them he placed an eiruv while it was still day, and for one he placed an eiruv at twilight, when it is uncertain whether it is day or night. The one for whom he placed an eiruv while it was still day had his eiruv eaten during twilight, and the one for whom he placed an eiruv during twilight had his eiruv eaten after nightfall. The principle is as follows: Whether or not an eiruv takes effect is determined at the moment that Shabbat begins. If one placed the eiruv beforehand, and it remains intact at the moment Shabbat begins, the eiruv is in effect. However, if the eiruv that was placed at the appropriate time was eaten during twilight, it is problematic. Twilight is a period of uncertainty. There is uncertainty whether it is day, and consequently the eiruv was not in place at the moment that Shabbat began, or whether it is night, and it was in place. In the latter case, there is still uncertainty as to whether or not the eiruv was in place prior to Shabbat, so that it could take effect at all. In that case, Rava ruled that both of them acquired the eiruv.
מָה נַפְשָׁךְ. אִי בֵּין הַשְּׁמָשׁוֹת יְמָמָא הוּא — בָּתְרָא לִיקְנֵי קַמָּא לָא לִיקְנֵי. וְאִי בֵּין הַשְּׁמָשׁוֹת לֵילְיָא הוּא — קַמָּא לִיקְנֵי בָּתְרָא לָא לִיקְנֵי! בֵּין הַשְּׁמָשׁוֹת סְפֵקָא הוּא, וּסְפֵקָא דְרַבָּנַן לְקוּלָּא.
The Gemara is surprised by this: Whichever way you look at it, this ruling is difficult. If the twilight period is considered day, let the latter one acquire his eiruv, but let the first one not acquire his because his eiruv was eaten while it was still day. And if the twilight period is night, let the first one acquire his eiruv, but let the latter one not acquire his eiruv because his was not placed before Shabbat. In any event, it is impossible for the eiruv in both of these cases to be valid. The Gemara answers this according to Rava’s position: The status of twilight is uncertain, as it is unknown whether it is day, or night, or both, and uncertainty in the case of a rabbinic ordinance is ruled leniently. Therefore, in both cases the eiruv is acquired.
[אָמַר] רָבָא: מִפְּנֵי מָה אָמְרוּ אֵין טוֹמְנִין בְּדָבָר שֶׁאֵינוֹ מוֹסִיף הֶבֶל מִשֶּׁחָשֵׁכָה? — גְּזֵרָה שֶׁמָּא יַרְתִּיחַ. אֲמַר לֵיהּ אַבָּיֵי: אִי הָכִי, בֵּין הַשְּׁמָשׁוֹת נָמֵי נִיגְזַר?! אֲמַר לֵיהּ: סְתָם קְדֵירוֹת רוֹתְחוֹת הֵן.
And Rava said: Why did they say that one may not insulate hot water even in something that does not add heat, but only retains the pre-existing heat, from nightfall on Friday? It is a decree lest one come to boil the pot on Shabbat. Abaye said to him: If so, if it is due to concern that one may boil it, then during twilight we should also issue a decree and prohibit insulating in something that does not add heat. Rava said to him: During twilight, there is no reason to be concerned because at that time most pots are boiling, as they have just been taken off of the fire. Later at night the pots cool down and it is conceivable that one may come to boil them in order to restore the heat.
וְאָמַר רָבָא:
And Rava said:
מִפְּנֵי מָה אָמְרוּ אֵין טוֹמְנִין בְּדָבָר הַמּוֹסִיף הֶבֶל וַאֲפִילּוּ מִבְּעוֹד יוֹם? — גְּזֵירָה שֶׁמָּא יַטְמִין בְּרֶמֶץ שֶׁיֵּשׁ בָּהּ גַּחֶלֶת. אֲמַר לֵיהּ אַבָּיֵי: וְיַטְמִין? גְּזֵירָה שֶׁמָּא יְחַתֶּה בַּגֶּחָלִים.
Why did the Sages say that one may not insulate hot water for Shabbat in something that adds heat, even while it is still day? It is a decree lest one come to cover it in hot ashes that contain a glowing ember. People may not differentiate between addition of heat by means of hot ashes and other additions of heat. Abaye said to him: Let him insulate it with hot ashes, what is the problem? Rava answered him: It is a decree lest one come to stoke the coals in order to make them burn on Shabbat and thereby violate a Torah prohibition.
תָּנוּ רַבָּנַן: בֵּין הַשְּׁמָשׁוֹת סָפֵק מִן הַיּוֹם וּמִן הַלַּיְלָה, סָפֵק כּוּלּוֹ מִן הַיּוֹם, סָפֵק כּוּלּוֹ מִן הַלַּיְלָה — מְטִילִין אוֹתוֹ לְחוֹמֶר שְׁנֵי יָמִים.
The Sages taught a baraita which discusses the range of problems that arise with regard to the twilight period. Twilight is a period of uncertainty. It is uncertain whether it consists of both day and night, it is uncertain whether it is completely day, and it is uncertain whether it is completely night. Therefore, the Sages impose the stringencies of both days upon it. If there is a stringency that applies on either of the days, one is obligated to adhere to it during the twilight period.
וְאֵיזֶהוּ בֵּין הַשְּׁמָשׁוֹת? — מִשֶּׁתִּשְׁקַע הַחַמָּה כָּל זְמַן שֶׁפְּנֵי מִזְרָח מַאֲדִימִין. הִכְסִיף הַתַּחְתּוֹן וְלֹא הִכְסִיף הָעֶלְיוֹן — בֵּין הַשְּׁמָשׁוֹת. הִכְסִיף הָעֶלְיוֹן וְהִשְׁוָה לַתַּחְתּוֹן — זֶהוּ לַיְלָה, דִּבְרֵי רַבִּי יְהוּדָה. רַבִּי נְחֶמְיָה אוֹמֵר: כְּדֵי שֶׁיְּהַלֵּךְ אָדָם מִשֶּׁתִּשְׁקַע הַחַמָּה חֲצִי מִיל. רַבִּי יוֹסִי אוֹמֵר: בֵּין הַשְּׁמָשׁוֹת כְּהֶרֶף עַיִן, זֶה נִכְנָס וְזֶה יוֹצֵא, וְאִי אֶפְשָׁר לַעֲמוֹד עָלָיו.
Nevertheless, the definition of twilight is uncertain. And what is twilight? From when the sun sets, as long as the eastern face of the sky is reddened by the light of the sun. If the lower segment of the sky has lost its color, and the upper segment has not yet lost its color, that is the twilight period. If the upper segment has lost its color, and its color equals that of the lower one, it is night; this is the statement of Rabbi Yehuda. Rabbi Neḥemya says: The duration of the twilight period is the time it takes for a person to walk half a mil after the sun sets. Rabbi Yosei says: Twilight does not last for a quantifiable period of time; rather, it is like the blink of an eye: This, night, enters and that, day, leaves, and it is impossible to calculate it due to its brevity.
אָמַר מָר: מְטִילִין אוֹתוֹ לְחוֹמֶר שְׁנֵי יָמִים. לְמַאי הִלְכְתָא? אָמַר רַב הוּנָא בְּרֵיהּ דְּרַב יְהוֹשֻׁעַ לְעִנְיַן טוּמְאָה, כְּדִתְנַן: רָאָה שְׁנֵי יָמִים בֵּין הַשְּׁמָשׁוֹת — סָפֵק לַטּוּמְאָה וְלַקׇּרְבָּן. רָאָה יוֹם אֶחָד בֵּין הַשְּׁמָשׁוֹת — סָפֵק לַטּוּמְאָה.
It was taught in the baraita that the Master said: The Sages impose the stringencies of both days upon twilight. The Gemara asks: With regard to what halakha was this stated? Rav Huna, son of Rav Yehoshua, said: With regard to the matter of ritual impurity, as we learned in a mishna: With regard to a zav who saw an emission for two consecutive days during twilight, it is unclear whether it should be considered as if he only saw the emission for a single day, as perhaps twilight of the first day was part of the following day, and twilight of the second day was part of the previous day; or, whether it should be considered as two days, attributing each twilight to either the previous or the following day; or, whether it should be considered three days, as it is possible to view the twilight period as two days. By Torah law, a zav who saw two emissions is ritually impure, and all of the stringencies of a zav apply to him. If he sees a third emission, he is liable to bring an offering as part of his purification ritual. Therefore, this zav, with regard to whom there is uncertainty whether he saw emissions for one day, two days, or three days, has uncertain status with regard to both ritual impurity and to sacrifice. If he saw an emission one day during twilight, he has uncertain status with regard to ritual impurity because it may be considered two days.

The Gemara comments on the baraita cited by the Gemara. This baraita is itself difficult, self-contradictory. Initially you said, what is twilight? From when the sun sets, as long as the eastern face of the sky is reddened by the light of the sun. By inference, if the bottom segment lost its color, and the upper one has not lost its color, it is night. And then the baraita taught: If the lower segment of the sky has lost its color, and the upper segment has not yet lost its color, that is the twilight period. There is an apparent internal contradiction in the baraita. Rabba said that Rav Yehuda said that Shmuel said: In order to resolve the contradiction, unify the two statements and teach it as follows: What is twilight? From when the sun sets, as long as the eastern face of the sky is reddened by the light of the sun. If the lower segment of the sky has lost its color and the upper segment has not yet lost its color, that is also the twilight period. Only if the upper segment lost its color, and it equals that of the lower one, is it night. And Rav Yosef said that Rav Yehuda said that Shmuel said otherwise: From when the sun sets, as long as the eastern face of the sky is reddened by the light of the sun, it is day. If the lower segment of the sky has lost its color, and the upper segment has not yet lost its color, that is the twilight period. If the upper segment lost its color and it equals that of the lower one, it is night.

And the Gemara remarks: In this dispute over the precise definition of twilight both Rabba and Rav Yosef follow their line of reasoning stated elsewhere. As it was stated: What is the measure of the duration of twilight? Rabba said that Rav Yehuda said that Shmuel said: The time it takes to walk three parts of a mil. The Gemara asks: What is the meaning of three parts of a mil? If you say that it refers to three halves of a mil, let him say a mil and a half. Rather, if you say that it means three-thirds of a mil, let him simply say one mil. Rather, it means three-quarters of a mil. And Rav Yosef said that Rav Yehuda said that Shmuel said: The duration of twilight is two parts of a mil. Again the Gemara asks: What is the meaning of two parts of a mil? If you say that it means two halves of a mil, let him simply say one mil. Rather, if you say that it means two-quarters of a mil, let him say instead: Half of a mil. Rather,
