Leviticus 4:7-12

The priest shall then put some of the blood on the horns of the altar of fragrant incense that is before the LORD in the tent of meeting. The rest of the bull’s blood he shall pour out at the base of the altar of burnt offering at the entrance to the tent of meeting. He shall remove all the fat from the bull of the sin offering—all the fat that is connected to the internal organs, both kidneys with the fat on them near the loins, and the long lobe of the liver, which he will remove with the kidneys— just 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. But the hide of the bull and all its flesh, as well as the head and legs, the internal organs and the intestines— that 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.
