1 tn Heb “a memorial of loud blasts.” Although the term for “horn” does not occur here, allowing for the possibility that vocal “shouts” of acclamation are envisioned (see P. J. Budd, Leviticus [NCBC], 325), the “blast” of the shofar (a trumpet made from a ram’s “horn”) is most likely what is intended. On this occasion, the loud blasts on the horn announced the coming of the new year on the first day of the seventh month (see the explanations in J. E. Hartley, Leviticus [WBC], 387, and B. A. Levine, Leviticus [JPSTC], 160).
2 sn On the “loud horn blasts” see the note on Lev 23:24, but unlike the language there, the Hebrew term for “horn” (שׁוֹפָר, shofar) actually appears here in this verse (twice).
