Leviticus 1:5-9

5And he shall kill the bullock before Jehovah: and Aaron’s sons, the priests, shall present the blood, and sprinkle the blood round about upon the altar that is at the door of the tent of meeting. 6And he shall flay the burnt-offering, and cut it into its pieces. 7And the sons of Aaron the priest shall put fire upon the altar, and lay wood in order upon the fire; 8and Aaron’s sons, the priests, shall lay the pieces, the head, and the fat, in order upon the wood that is on the fire which is upon the altar: 9but its inwards and its legs shall he wash with water. And the priest shall burn the whole on the altar, for a burnt-offering, an offering made by fire, of a sweet savor unto Jehovah.
