Leviticus 8:18-21

And he brought the ram for the burnt offering: and Aaron and his sons laid their hands upon the head of the ram. And he killed it; and Moses sprinkled the blood upon the altar round about. And he cut the ram into pieces; and Moses burnt the head, and the pieces, and the fat. And he washed the inwards and the legs in water; and Moses burnt the whole ram upon the altar: it was a burnt sacrifice for a sweet savour, and an offering made by fire unto the LORD; as the LORD commanded Moses.
