📜Five Testimonies
Rabbi Yehuda ben Bava testified about five things, including that the daily morning offering was once brought at four hours. Rav Kahana says this proves the halakha follows Rabbi Yehuda, since this was taught in the tractate Eduyyot. It shows that 'until' can mean 'until and including.'
Amud a 🙏Praying Behind Rav
Rav prayed the Shabbat prayer early at Geniva's house, and Rabbi Yirmeya bar Abba prayed right behind him. Rav finished but waited, careful not to interrupt Rabbi Yirmeya's prayer. From this the Gemara learns three things: you may pray Shabbat prayers early, a student may pray behind his rabbi, and it is forbidden to walk in front of people who are praying.
Amud a ⚖️Optional or Obligatory?
A student asked Rabbi Yehoshua if the evening prayer is optional, and he said yes. Then Rabban Gamliel said it is obligatory, and made Rabbi Yehoshua stand up in front of everyone to admit he had said 'optional.' The Sages grew upset at how Rabban Gamliel treated Rabbi Yehoshua, so they removed him as leader and chose Rabbi Elazar ben Azarya instead, because he was wise, rich, and descended from Ezra.
