Leviticus 8:18-21

Next Moses brought the male sheep of the burnt offering, and Aaron and his sons put their hands on its head. Then Moses killed it and sprinkled the blood on all sides of the altar. He cut the male sheep into pieces and burned the head, the pieces, and the fat. He washed the inner organs and legs with water and burned the whole sheep on the altar as a burnt offering made by fire to the LORD; its smell was pleasing to the LORD. Moses did these things as the LORD had commanded him.
