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 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.

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.
