Leviticus 3:9-11

New Century Version

⁹ From the fellowship offering the person must make a sacrifice by fire to the Lord. He must bring the fat, the whole fat tail cut off close to the backbone, the fat of the inner organs (both the fat that is in them and that covers them), ¹⁰ both kidneys with the fat that is on them, near the lower back muscle, and the best part of the liver, which he will remove with the kidneys. ¹¹ Then the priest will burn these parts on the altar as food; it will be an offering made by fire to the Lord.
