Numbers 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.

Numbers 28:10

28:10 This is the burnt offering for every Sabbath, ²  besides the continual burnt offering and its drink offering.

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.

² tn Heb “the burnt offering of the Sabbath by its Sabbath.”
