Exodus 29:13

10 "You shall bring the bull before the tent of meeting: and Aaron and his sons shall lay their hands on the head of the bull.

11 You shall kill the bull before Yahweh, at the door of the tent of meeting.

12 You shall take of the blood of the bull, and put it on the horns of the altar with your finger; and you shall pour out all the blood at the base of the altar.

13 You shall take all the fat that covers the innards, the cover of the liver, the two kidneys, and the fat that is on them, and burn them on the altar.

14 But the flesh of the bull, and its skin, and its dung, you shall burn with fire outside of the camp: it is a sin-offering.

15 "You shall also take the one ram; and Aaron and his sons shall lay their hands on the head of the ram.

16 You shall kill the ram, and you shall take its blood, and sprinkle it around on the altar.
