Bilangan 28:3

28:3 You will say to them, ‘This is the offering made by fire which you must offer to the Lord: two unblemished lambs one year old each day for a continual ¹  burnt offering.

Bilangan 28:19

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 

[28:3]  ¹ sn The sacrifice was to be kept burning, but each morning the priests would have to clean the grill and put a new offering on the altar. So the idea of a continual burnt offering is more that of a regular offering.

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