Leviticus 3:13-15

American Standard Version

¹³ and he shall lay his hand upon the head of it, and kill it before the tent of meeting; and the sons of Aaron shall sprinkle the blood thereof upon the altar round about. ¹⁴ And he shall offer thereof his oblation, even an offering made by fire unto Jehovah; the fat that covereth the inwards, and all the fat that is upon the inwards, ¹⁵ 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.
