Leviticus 4:8-12

8And all the fat of the bullock of the sin-offering he shall take off from it; the fat that covereth the inwards, and all the fat that is upon the inwards, 9and the two kidneys, and the fat that is upon them, which is by the loins, and the caul upon the liver, with the kidneys, shall he take away, 10as it is taken off from the ox of the sacrifice of peace-offerings: and the priest shall burn them upon the altar of burnt-offering. 11And the skin of the bullock, and all its flesh, with its head, and with its legs, and its inwards, and its dung, 12even the whole bullock shall he carry forth without the camp unto a clean place, where the ashes are poured out, and burn it on wood with fire: where the ashes are poured out shall it be burnt.
