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 28:24

28:24 In this manner you must offer daily throughout the seven days the food of the sacrifice made by fire as a sweet aroma to the Lord. It is to be offered in addition to the continual burnt offering and its drink offering.

[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.
