Leviticus 7:3-5

Modern English Version

³ He shall offer all the fat. The fatty tail and the fat that covers the entrails, ⁴ and the two kidneys and the fat that is on them, which is on the loins, and the appendage that is above the liver, along with the kidneys, he shall take away. ⁵ And the priest shall burn them on the altar for a food offering made by fire to the Lord. It is a guilt offering.
