Leviticus 7:3-7

3The offerer is to present all the fat from it: the fat tail, the fat surrounding the entrails,

4and the two kidneys with the fat on them at the loins; he will also remove the fatty lobe of the liver with the kidneys.

5The priest will burn them on the altar as a food offering to the Lord; it is a guilt offering.

6Any male among the priests may eat it. It is to be eaten in a holy place; it is especially holy.

7“The guilt offering is like the sin offering; the law is the same for both. It belongs to the priest who makes atonement with it.
