Exodus 29:15 KJV

13And 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.

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

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

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

17And 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.
