Leviticus 3:9-11

9From the 1sacrifice of peace offerings he shall bring as an offering by fire to the Lord, its fat, 2the entire fat tail which he shall remove close to the backbone, and the fat that covers the entrails and all the fat that is on the entrails, 10and the two kidneys with the fat that is on them, which is on the loins, and the 3lobe of the liver, which he shall remove 4with the kidneys. 11Then the priest shall offer it up in smoke 5on the altar as 6food, an offering by fire to the Lord.
