Sugya Map: The Paradox of Yom Teruah

• Issue: The tension between the Torah's designation of the day as Yom Teruah (Numbers 29:1) and the Mishnaic requirement of Mussaf as the primary location for the mitzvah.
• Primary Sources: Numbers 29:1; Rosh Hashanah 29b; Yerushalmi Rosh Hashanah 4:8; Torah Temimah (ad loc).
• Nafka Mina: Does the mitzvah reside in the day (all day) or in the tefillah (specifically Mussaf)?

Text Snapshot

"בַּחֹדֶשׁ הַשְּׁבִיעִי בְּאֶחָד לַחֹדֶשׁ... יוֹם תְּרוּעָה יִהְיֶה לָכֶם." (Numbers 29:1)

The Leshon "יהיה לכם" is the fulcrum. While Chazal (RH 29b) debate whether teruah occurs when Rosh Hashanah falls on Shabbat, the Torah Temimah notes the Yerushalmi’s radical expansion: “יהיה לכם”—a ribbui—permits even problematic shofarot (e.g., avodah zarah) because the mitzvah is the act of hearing the sound, which lacks physical hana’ah (benefit).

Readings

• Rambam (Hilchot Shofar 3:10): Fixes the minhag to sit during the pre-Mussaf blasts. The chiddush is that sitting serves as a liturgical signal: since the core mitzvah (defined by the Mussaf structure) requires standing, sitting distinguishes the "extra" blasts from the chovah.
• Torah Temimah: Proposes that the shift from Shacharit to Mussaf—originally a protective measure against Roman persecution—was cemented into halacha because the Mussaf is the "proper" place for the teruah as hinted by the proximity in the text ("...יום תרועה יהיה לכם ועשיתם עולה").

Friction

• Kushya: If the Mussaf placement was merely d'rabbanan due to persecution, why not revert to Shacharit (the time of zerizin makdimin) upon the cessation of the decree?
• Terutz: Per the Yerushalmi, the Mussaf is the mekom ha-mitzvah by design. The historical decree merely realigned our practice with the deeper textual intent found in the sequence of offerings.

Psak/Practice

The minhag of sitting during the tekiot before Mussaf is a "meta-psak" heuristic: it preserves the distinction between the hachana (preparation/distraction of the Satan) and the chovah (the Mussaf service itself). We treat the shofar as a functional tool within the liturgy rather than an independent act.

Takeaway

The teruah is not merely a sound; it is a structural component of the Mussaf offering. We sit during the initial blasts to affirm that the real work happens when we stand for the Mussaf itself.
