Numbers 28:18-19

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 

[28:18]  ¹ tn Heb “any work [of] service”; this means any occupational work, that is, the ordinary service.

[28:19]  ² tn Heb “unblemished they will be to you.” So also in v. 31.
