Rosh Hashanah 29b to 30a (chazara)

AI summary (may contain mistakes)

Why is the shofar not blown when Rosh Hashanah falls on Shabbos, and where did Rabban Yochanan ben Zakkai bring it back after the Churban? The Gemara answers that d'Oraisa blowing is no issur, but the Rabbanan made a gezeira, following Rabba, lest a person carry the shofar to an expert. Rav Huna's words "with beis din" mean in front of the beis din. The Gemara concludes that Yerushalayim had two edges over Yavne: the nearby towns blew too, and blowing there was not limited to in front of the beis din.

Key points

• Following Rabba, the Rabbanan stopped blowing on Shabbos lest one carry the shofar to an expert.
• Per the Gemara, a traveling beis din blows for the Tanna Kama but not for Amru lo.
• Per the Gemara, Yerushalayim blew even away from the beis din, unlike Yavne.
