Leviticus 3:9 ASV

⁷  If he offer a lamb for his oblation, then shall he offer it before Jehovah;

⁸  and he shall lay his hand upon the head of his oblation, and kill it before the tent of meeting: and Aaron's sons shall sprinkle the blood thereof upon the altar round about.

⁹  And he shall offer of the sacrifice of peace-offerings an offering made by fire unto Jehovah; the fat thereof, the fat tail entire, he shall take away hard by the backbone; and the fat that covereth the inwards, and all the fat that is upon the inwards,

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

¹¹  And the priest shall burn it upon the altar: it is the food of the offering made by fire unto Jehovah.
