Leviticus 4:8-12

8He shall remove all the fat from the bull of the sin offering—all the fat that is connected to the internal organs, 9both kidneys with the fat on them near the loins, and the long lobe of the liver, which he will remove with the kidneys— 10just as the fat is removed from the ox sacrificed as a fellowship offering. Then the priest shall burn them on the altar of burnt offering. 11But the hide of the bull and all its flesh, as well as the head and legs, the internal organs and the intestines— 12that is, all the rest of the bull—he must take outside the camp to a place ceremonially clean, where the ashes are thrown, and burn it there in a wood fire on the ash heap.
