Leviticus 3:8

5 Aaron`s sons shall burn it on the altar on the burnt offering, which is on the wood that is on the fire: it is an offering made by fire, of a sweet savor to Yahweh.

6 If his offering for a sacrifice of peace-offerings to Yahweh be of the flock; male or female, he shall offer it without blemish.

7 If he offer a lamb for his offering, then shall he offer it before Yahweh;

8 and he shall lay his hand on the head of his offering, and kill it before the tent of meeting: and Aaron`s sons shall sprinkle the blood of it on the altar round about.

9 He shall offer of the sacrifice of peace-offerings an offering made by fire to Yahweh; the fat of it, the fat tail entire, he shall take away hard by the backbone; and the fat that covers the inwards, and all the fat that is on the inwards,

10 and the two kidneys, and the fat that is on them, which is by the loins, and the cover on the liver, with the kidneys, shall he take away.

11 The priest shall burn it on the altar: it is the food of the offering made by fire to Yahweh.
