Rosh Hashana | How Did We Get To 30 Blasts?

Rosh Hashana | How Did We Get To 30 Blasts? by Rav Yitzchak Etshalom

Why do we blow 30 shofar blasts from one vague word in the Torah? The answer involves doubt, unity, and Caesarea.

This shiur explores the halakhic development of the shofar blowing on Rosh Hashana, tracing the transition from the Torah's vague command of 'Yom Terua' to the established practice of 30 sounds. Rabbi Etshalom analyzes the Sifra's hermeneutic process to identify the shofar as the required instrument and the structure of the blasts. Finally, the lecture examines the Gemara's account of Rabbi Abbahu's takkana, which unified diverse regional customs into the comprehensive sequence of sounds performed today.
