1because he must recite havdala in the blessing: Who graciously grants knowledge, and there is nowhere to insert this prayer in the abridged Amida . This indicates that these tanna’im maintained that ne’ila does not exempt one from the evening prayer. The Gemara answers: It is a dispute between tanna’im , as it was taught in a baraita : Anyone who requires immersion immerses in his usual manner on Yom Kippur, as this act does not violate the prohibition against washing. A menstruating woman and a new mother, who immerse at night, immerse in their usual manner on the night of Yom Kippur.
2The baraita continues: One who had a seminal emission during Yom Kippur before the afternoon prayer may immerse at any point in the day until the afternoon prayer, in order to be able to recite it. Ezra decreed that a man who has had a seminal emission must immerse in order to pray and study Torah. If the emission occurred after the afternoon prayer, he should not immerse then but should wait until darkness falls. Since the time for ne’ila is at night, this individual should wait and immerse after the fast has concluded, so as to avoid violation of the prohibition of washing on Yom Kippur, and then pray afterward. This indicates that ne’ila is a nighttime prayer, and therefore its recitation exempts one from the weekday evening prayer. Rabbi Yosei says: He may immerse at any point in the day. According to his opinion, the ne’ila prayer is recited while it is still daytime, and therefore the individual must immerse in the daytime in order to be able to recite it. Consequently, Rabbi Yosei holds that ne’ila does not exempt one from the evening prayer.
3The Gemara raises a contradiction with regard to this baraita from that which was taught: In the case of the zav , and the zava , the male and female leper, and one who had relations with a menstruating woman, and one who is ritually impure through contact with a corpse, if their time has come for purification, they immerse in their usual manner on Yom Kippur. A menstruating woman and a woman after childbirth immerse in their usual manner on the night of Yom Kippur. One who had a seminal emission immerses at any point in the day. Rabbi Yosei says: From the time of the afternoon prayer onward he is not able to immerse. This contradicts Rabbi Yosei’s statement in the previous baraita .
4The Gemara answers: This is not difficult. This statement, in which Rabbi Yosei says that one may not immerse during the day, is referring to a case where he had already prayed the ne’ila prayer before he noticed his seminal emission. That statement, in which Rabbi Yosei says that one may immerse during the day, is referring to a case where he had not yet prayed the ne’ila prayer when he noticed his seminal emission, and he therefore immerses in order to pray ne’ila .
5The Gemara asks: If he had already prayed ne’ila before he noticed his seminal emission, what is the reasoning of the Rabbis, who permit him to immerse on Yom Kippur? The immersion seems to have no purpose. The Gemara answers: The Rabbis hold that immersion at its proper time is a mitzva, even when one does not need to immerse to pray. Therefore, if the time for immersion falls on Yom Kippur, the individual should immerse as usual.
6The Gemara asks: By inference, Rabbi Yosei holds that immersion at its proper time is not a mitzva. But wasn’t it taught in a baraita : If God’s name is written in ink on one’s flesh, he may not wash and he may not smear it with oil lest he erase the name, and he may not stand in a filthy place out of respect for the name. If his time came for an immersion that is a mitzva, he must try to ensure that the name not be erased. He therefore wraps a reed around it and descends and immerses. Rabbi Yosei says: He descends and immerses in his usual manner and need not worry about erasing the name, provided he does not rub the place where the name is written.
7And we maintain that they disagree as to whether or not immersion at its proper time is a mitzva. According to the Rabbis, immersion at its proper time is not a mitzva. Therefore, if the individual has no reed, he should wait even until the following day rather than immerse without it. However, Rabbi Yosei maintains that immersion at its proper time is a mitzva. Therefore, it must be done at its proper time, even if that requires immersion without covering God’s name.
8The Gemara answers: This Rabbi Yosei mentioned in the baraita is actually Rabbi Yosei bar Yehuda, and this resolves the contradiction, as it was taught in a baraita that Rabbi Yosei bar Yehuda says: It is sufficient for the immersion to be at the end. According to one opinion, if a menstruating woman is uncertain on which day to immerse, she immerses multiple times to ensure that the required immersion is at its proper time. However, according to Rabbi Yosei bar Yehuda, it is sufficient for her to immerse once at a point when she is certainly pure. Consequently, according to his opinion, there is no mitzva to immerse at the proper time.
9The Sages taught: One who sees an emission of semen on Yom Kippur descends and immerses. And in the evening, he should rub his skin to remove anything that might obstruct the immersion. The Gemara is surprised at this: Why should he do that in the evening? What was, was. Since he has already immersed, how will removing interpositions afterward benefit the immersion? Rather, say that he should rub his skin from the evening before Yom Kippur to remove any obstructions, in case it becomes necessary to immerse on Yom Kippur. The Gemara comments: This Master holds that it is a mitzva to rub.
10§ Apropos the halakhot of immersion for one who has had a seminal emission on Yom Kippur, the Gemara relates: A tanna taught a baraita before Rav Naḥman: With regard to one who sees an emission of semen on Yom Kippur, his sins are forgiven. The Gemara asks: But wasn’t it taught in a baraita : His sins are arranged before him? The Gemara answers: What is the meaning of arranged? They are arranged to be forgiven.
11The school of Rabbi Yishmael taught: One who sees an emission of semen on Yom Kippur should worry the whole year that perhaps he was given a sign that he and his fast were rejected. But if he survives the year, he can be assured that his good deeds protected him and ensured for him a share in the World-to-Come. Rav Naḥman bar Yitzḥak said: Know that it is so, as the whole world is hungry due to refraining from conjugal relations, and he is satiated since he emitted semen and his lust was subdued. Since the issue was involuntary and not intentional, it is a sign that he has merited divine compassion. When Rav Dimi came from Eretz Yisrael to Babylonia he said: Seeing semen on Yom Kippur is a sign that one will live a long life, grow, and raise others. An allusion to that is the verse: “That he might see his seed and prolong his days” (Isaiah 53:10).
