Leviticus 3:14-16

New Catholic Bible

¹⁴ From it he will offer up the following as a burnt offering to the Lord: the fat covering and above its entrails, ¹⁵ its two kidneys with their fat, the fat around the loins, and the lobe of the liver that he will detach along with the kidneys. ¹⁶ Then the priest shall burn them on the altar as food offered to the Lord by fire. All fat belongs to the Lord.
