Leviticus 1:5-9

5And he shall slaughter the bullock before Jehovah; and Aaron's sons, the priests, shall present the blood and sprinkle the blood round about on the altar that is at the entrance of the tent of meeting.

6And he shall flay the burnt-offering, and cut it up into its pieces.

7And the 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 its inwards and its legs shall he wash in water; and the priest shall burn all on the altar, a burnt-offering, an offering by fire to Jehovah of a sweet odour.
