Exodus 29:14

11 And thou shalt kill the bullock before Jehovah, at the door of the tent of meeting.

12 And thou shalt take of the blood of the bullock, and put it upon the horns of the altar with thy finger; and thou shalt pour out all the blood at the base of the altar.

13 And thou shalt take all the fat that covereth the inwards, and the caul upon the liver, and the two kidneys, and the fat that is upon them, and burn them upon the altar.

14 But the flesh of the bullock, and its skin, and it dung, shalt thou burn with fire without the camp: it is a sin-offering.

15 Thou shalt also take the one ram; and Aaron and his sons shall lay their hands upon the head of the ram.

16 And thou shalt slay the ram, and thou shalt take its blood, and sprinkle it round about upon the altar.

17 And thou shalt cut the ram into its pieces, and wash its inwards, and its legs, and put them with its pieces, and with its head.
