Rosh Hashanah 29b Part 4/9

AI summary (may contain mistakes)

Why is the shofar not blown when Rosh Hashanah falls on Shabbos, and where was it blown after the Churban? The Gemara concludes the issur is d'Rabbanan, and Rabba explains it as a fear that someone will carry the shofar four amos. Rabban Yochanan ben Zakkai had the shofar blown in Yavna before the Bnei Beseira could debate it. A seeming repetition in the Mishnah turns out to be a machlokes about a beis din d'akrai.

Key points

• The same concern is why the lulav is not shaken and the Megillah not read on Shabbos.
• Rabban Yochanan ben Zakkai had the shofar blown first, then refused to reopen the question afterward.
• The Gemara says the Tanna Kamma and the amru lo differ over a beis din d'akrai.
• Rashi has the Tanna Kamma blowing there, the amru lo requiring a permanent beis din like Yavna.
