Leviticus 7:6

He shall offer all of its fat: the fat tail, and the fat that covers the innards,

and he shall take away the two kidneys, and the fat that is on them, which is by the loins, and the cover on the liver, with the kidneys;

and the priest shall burn them on the altar for an offering made by fire to the LORD: it is a trespass offering.

“‘As is the sin offering, so is the trespass offering; there is one law for them. The priest who makes atonement with them shall have it.

The priest who offers any man’s burnt offering shall have for himself the skin of the burnt offering which he has offered.

Every meal offering that is baked in the oven, and all that is prepared in the pan and on the griddle, shall be the priest’s who offers it.
