Leviticus 9:12-14 - The Burnt Offering For The Priests
12 Then he slaughtered the burnt offering, and Aaron's sons brought the blood to him, and he sprinkled it on the altar all around; 13 and they brought the burnt offering to him by its pieces, as well as the head, and he turned [them] into smoke on the altar; 14 and he washed the inner parts and the lower leg bones, then he turned [them] into smoke upon the burnt offering on the altar.
