Leviticus 7:4-8

and the two kidneys with the fat that is on them, which is on the loins; and he shall remove the lobe on the liver with the kidneys.

The priest shall offer them up in smoke on the altar as an offering by fire to the Lord; it is a guilt offering.

Every male among the priests may eat it. It shall be eaten in a holy place; it is most holy.

The guilt offering is like the sin offering: there is one law for them. The priest who makes atonement with it shall have it.

Also the priest who presents anyone’s burnt offering, that priest shall have for himself the hide of the burnt offering which he has presented.
