Leviticus 8:18-21

And he presented the ram of 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 its pieces; and Moses burnt the head, and the pieces, and the fat. And he washed the inwards and the legs with water; and Moses burnt the whole ram upon the altar: it was a burnt-offering for a sweet savor: it was an offering made by fire unto Jehovah; as Jehovah commanded Moses.
