Today's daf is sponsored by Peri Rosenfeld in honor of the Yahrzeit of her mother, Tovah Bodek Rosenfeld. "Her devotion to Judaism and life-long learning has been a continued source of inspiration". And by Onnie and Andy Schiffmiller in honor of Andy’s mother having made Aliyah yesterday ושבו בנים לגבולם. Mazal Tov. Rav held like Rabbi Yehuda regarding the time for forbidding eating chametz on Erev Pesach. The gemara questions - why didn't he hold like Rabbi Meir, as there is an unattributed mishna which holds like him, or Rabban Gamliel as he holds the compromise approach? Could it be Rav held like Rabbi YEhuda really because he held like a different tanna who also happened to hold like Rabbi Yehuda? The gemara rejects that suggestion. The gemara brings a source to show that Rabbi Yehuda HaNasi also held like Rabbi Yehuda (to strengthen Rav's psak). The gemara explains where the disqualified bread from the THanksgiving offering was placed in order to let the people know when were the times that chametz was forbidden or needed to be burned. In what way had they become disqualified? Two suggestions are brought. Others say that they weren't disqualified breads at all and others say that two cows would be set up to plow on the Mount of Olives instead of breads.
