Exodus 29:14

11 And thou shalt kill the bullock before the LORD, by the door of the tabernacle of the congregation.

12 And thou shalt take of the blood of the bullock, and put it upon the horns of the altar with thy finger, and pour all the blood beside the bottom of the altar.

13 And thou shalt take all the fat that covereth the inwards, and the caul that is above 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 his skin, and his dung, shalt thou burn with fire without the camp: it is a sin offering.

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

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

17 And thou shalt cut the ram in pieces, and wash the inwards of him, and his legs, and put them unto his pieces, and unto his head.
