Rosh Hashanah 29b Part 3/9

AI summary (may contain mistakes)

Why is shofar not blown on a Rosh Hashanah that falls on Shabbos? The Gemara first finds a d'Oraisa source in two pesukim, then asks why the Mikdash blew on Shabbos, and how the Torah could bar blowing when it is no melacha at all. Rava answers that m'd'Oraisa the Torah permits blowing. The Rabbanan made the gezeira of Rabbah, the same one behind not taking lulav and not reading the megillah on Shabbos.

Key points

• The Gemara reconciles zichron teruah and yom teruah: one pasuk for Shabbos, one for a weekday.
• The Gemara asks how the Mikdash could blow on Shabbos if the issur were d'Oraisa.
• A beraisa from the yeshiva of Shmuel calls tekias shofar and redias hapas a chochmah, not a melacha.
• In Rabbah's gezeira, one might carry a shofar four amos in reshus harabim to an expert.
• Chazal can tell us to hold back from a mitzvah, but never to do an aveira.
