Leviticus 1:7

5He shall kill the bull before the LORD. Aaron’s sons, the priests, shall present the blood and sprinkle the blood around on the altar that is at the door of the Tent of Meeting.

6He shall skin the burnt offering and cut it into pieces.

7The sons of Aaron the priest shall put fire on the altar, and lay wood in order on the fire;

8and Aaron’s sons, the priests, shall lay the pieces, the head, and the fat in order on the wood that is on the fire which is on the altar;

9but he shall wash its innards and its legs with water. The priest shall burn all of it on the altar, for a burnt offering, an offering made by fire, of a pleasant aroma to the LORD.
