Leviticus 3:9-11

King James Version

⁹ And 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 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 flanks, and the caul above the liver, with the kidneys, it 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 the Lord.
