Leviticus 9:12-14 - The Burnt Offering For The Priests
12 And he slaughtered the burnt-offering; and Aaron's sons delivered to him the blood, which he sprinkled on the altar round about. 13 And they delivered the burnt-offering to him, in the pieces thereof, and the head; and he burned them on the altar. 14 And he washed the inwards and the legs, and burned them upon the burnt-offering, on the altar.
