Leviticus 9:12-14

¹²And he slew the burnt-offering; and the sons of Aaron presented unto him the blood, and he sprinkled it upon the altar round about.

¹³And the burnt-offering they presented unto him, in its proper pieces, together with the head: and he burnt them upon the altar.

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