⁹ Then from the sacrifice of the peace offering as an offering by fire to the Lord he shall offer its fat, the fat tail entire, taking it away close by the backbone, and the fat that covers the entrails, and all the fat that is on the entrails, ¹⁰ and the two kidneys with the fat that is on them at the loins, and the appendage of the liver which he shall take away with the kidneys. ¹¹ And the priest shall burn it on the altar as food offered by fire to the Lord.
