Today's daf is sponsored by Tina Lamm's children in memory of their grandfather, Mike Senders z"l, from Cleveland, Ohio, and later Boca Raton, Florida. "He dedicated much of his life to growing strong Jewish institutions, and his passion for Judaism, Torah, and Tefilla serves as a constant inspiration for us. May his neshama have an aliya and his memory be for a blessing."

A braita is brought to raise a difficulty on Rabbi Meir's position. The braita mentions two specific sin offerings whose meat is not eaten – the Levites' miluim offering and the offerings brought in the time of Ezra by those who returned to Zion. The latter offering consisted of twelve bulls and twelve goats. The Gemara assumes they were a communal sin offering for idol worship by the people during the time of Zedekiah. This number of sacrifices accords with Rabbi Yehuda's opinion that each tribe brings a bull and goat, and Rabbi Shimon's opinion that both the tribes and the court bring (in a case where eleven tribes sinned), but it does not accord with Rabbi Meir's opinion that only the court brings the sacrifice, as there should be only one bull and one goat. This difficulty is resolved by the suggestion that they sinned on twelve separate occasions.

Two other difficulties are raised on the braita. One, if the people of that time were already dead, how could the sin offering be brought, as an animal designated for a sin offering whose owners died is left to die, as the sacrifice can no longer be offered? Rav Papa suggests that the sin offering is left to die only for an individual offering, but not for one brought by the community. Three potential explanations are brought as a source for Rav Papa's view, but all are rejected, and Rav Papa's answer is rejected as well. The Gemara then answers that the people were still alive and proves it from a verse in Ezra 3:12. The second question is, didn't they sin intentionally, in which case a sacrifice would not be able to be offered? They answer that it was a horaat sha'ah, unique circumstances, under which this was permitted. This answer can also resolve the previous difficulties.

A braita teaches that if one of the community died, the communal sin offering would still be brought, but if one of the judges who issued the ruling died, the community is exempt from bringing the offering. Which tanna is the author of this braita? Rav Chisda attributes it to Rabbi Meir, while Rav Yosef questions why it cannot be attributed to Rabbi Shimon as well. Abaye disagrees with Rav Yosef's suggestion, and there is a back-and-forth discussion between them. Ultimately, the Gemara sides with Abaye, based on a different source.

In what cases does a kohen gadol bring a bull sin offering?
