Leviticus 3:1-9

1 If the offering is a sacrifice of well-being, if you offer an animal of the herd, whether male or female, you shall offer one without blemish before the Lord.
2 You shall lay your hand on the head of the 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.
3 You shall offer 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 around the entrails;
4 the two kidneys with the fat that is on them at the loins, and the appendage of the liver, which he shall remove with the kidneys.
5 Then Aaron's sons shall turn these into smoke on the altar, with the burnt offering that is on the wood on the fire, as an offering by fire of pleasing odor to the Lord.
6 If your offering for a sacrifice of well-being to the Lord is from the flock, male or female, you shall offer one without blemish.
7 If you present a sheep as your offering, you shall bring it before the Lord
8 and lay your hand on the head of the offering. It shall be slaughtered before the tent of meeting, and Aaron's sons shall dash its blood against all sides of the altar.
9 You shall present its fat from the sacrifice of well-being, as an offering by fire to the Lord: the whole broad tail, which shall be removed close to the backbone, the fat that covers the entrails, and all the fat that is around the entrails;
