Leviticus 9:12-14

¹²And he slew the burnt-offering; and Aaron's sons presented to him the blood, which he sprinkled around upon the altar.

¹³And they presented the burnt-offering to him, with the pieces of it, and the head: and he burnt them upon the altar.

¹⁴And he washed the inwards and the legs, and burnt them upon the burnt-offering on the altar.
