Numbers 28:17-19

28:17 And on the fifteenth day of this month is the festival. For seven days bread made without yeast must be eaten. 28:18 And on the first day there is to be a holy assembly; you must do no ordinary work 1  on it.

28:19 “‘But you must offer to the Lord an offering made by fire, a burnt offering of two young bulls, one ram, and seven lambs one year old; they must all be unblemished. 2 

1 tn Heb “any work [of] service”; this means any occupational work, that is, the ordinary service.

2 tn Heb “unblemished they will be to you.” So also in v. 31.
