Leviticus 9:12-14 - The Burnt Offering For The Priests
12 Then he slaughtered the burnt offering. Aaron’s sons brought him the blood, and he sprinkled it on all sides of the altar. 13 They brought him the burnt offering piece by piece, along with the head, and he burned them on the altar. 14 He washed the entrails and the shanks and burned them with the burnt offering on the altar.
