Imamat 23:24

23:24 “Tell the Israelites, ‘In the seventh month, on the first day of the month, you must have a complete rest, a memorial announced by loud horn blasts, ¹  a holy assembly.

Bilangan 29:1

Blowing Trumpets

29:1 “‘On the first day of the seventh month, you are to hold a holy assembly. You must not do your ordinary work, for it is a day of blowing trumpets for you.

[23:24]  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).
