Leviticus 9:12-14

¹²And he slew the burnt offering; and Aaron’s sons presented unto him the blood, which he sprinkled round about upon the altar.

¹³And they presented the burnt offering unto him, with the pieces thereof, and the head: and he burnt them upon the altar.

¹⁴And he did wash the inwards and the legs, and burnt them upon the burnt offering on the altar.
