Leviticus 7:4-6

New Catholic Bible

⁴ the two kidneys with their fat, the fat around the loins, and the lobe of the liver that he will detach along with the kidneys. ⁵ The priest shall burn all of this on the altar as a burnt offering to the Lord. It is a guilt offering. ⁶ All of the males of the priestly family may eat it. They shall eat it in a holy place. It is most holy.
