Leviticus 3:6-10

⁶And if his offering for a sacrifice of peace offering unto the Lord be of the flock, male or female, he shall offer it without blemish.

⁷If he offer a lamb for his offering, then shall he offer it before the Lord.

⁸And he shall lay his hand upon the head of his offering, and kill it before the tabernacle of the congregation: and Aaron’s sons shall sprinkle the blood thereof round about upon the altar.

⁹And he shall offer of the sacrifice of the peace offering an offering made by fire unto the Lord; the fat thereof, and the whole rump, it shall he take off hard by the back bone; and the fat that covereth the inwards, and all the fat that is upon the inwards,

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