Leviticus 4:7-9

American Standard Version

⁷ And the priest shall put of the blood upon the horns of the altar of sweet incense before Jehovah, which is in the tent of meeting; and all the blood of the bullock shall he pour out at the base of the altar of burnt-offering, which is at the door of the tent of meeting. ⁸ And all the fat of the bullock of the sin-offering he shall take off from it; the fat that covereth the inwards, and all the fat that is upon the inwards, ⁹ 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,
