Leviticus 9:12-14 - The Burnt Offering For The Priests
12 And he slew the burnt-offering; and Aaron's sons presented to him the blood, which he sprinkled around upon the altar. 13 And they presented the burnt-offering to him, with the pieces of it, and the head: and he burnt them upon the altar. 14 And he washed the inwards and the legs, and burnt them upon the burnt-offering on the altar.
