Leviticus 3:1-3:17
If his offering is a sacrifice of well-being--
If he offers of the herd, whether a male or a female, he shall bring before the Lord one without blemish. He shall lay his hand upon the head of his offering and slaughter it at the entrance of the Tent of Meeting; and Aaron's sons, the priests, shall dash the blood against all sides of the altar. He shall then present from the sacrifice of well-being, as an offering by fire to the Lord, the fat that covers the entrails and all the fat that is about the entrails; the two kidneys and the fat that is on them, that is at the loins; and the protuberance on the liver, which he shall remove with the kidneys. Aaron's sons shall turn these into smoke on the altar, with the burnt offering which is upon the wood that is on the fire, as an offering by fire, of pleasing odor to the Lord.
And if his offering for a sacrifice of well-being to the Lord is from the flock, whether a male or a female, he shall offer one without blemish. If he presents a sheep as his offering, he shall bring it before the Lord and lay his hand upon the head of his offering. It shall be slaughtered before the Tent of Meeting, and Aaron's sons shall dash its blood against all sides of the altar. He shall then present, as an offering by fire to the Lord, the fat from the sacrifice of well-being: the whole broad tail, which shall be removed close to the backbone; the fat that covers the entrails and all the fat that is about the entrails; the two kidneys and the fat that is on them, that is at the loins; and the protuberance on the liver, which he shall remove with the kidneys. The priest shall turn these into smoke on the altar as food, an offering by fire to the Lord.
And if his offering is a goat, he shall bring it before the Lord and lay his hand upon its head. It shall be slaughtered before the Tent of Meeting, and Aaron's sons shall dash its blood against all sides of the altar. He shall then present as his offering from it, as an offering by fire to the Lord, the fat that covers the entrails and all the fat that is about the entrails; the two kidneys and the fat that is on them, that is at the loins; and the protuberance on the liver, which he shall remove with the kidneys. The priest shall turn these into smoke on the altar as food, an offering by fire, of pleasing odor.
All fat is the Lord's. It is a law for all time throughout the ages, in all your settlements: you must not eat any fat or any blood.
