Leviticus 7:3-10

³And all the fat of it, the fat tail and the fat covering the inside parts, is to be given as an offering.

⁴And the two kidneys, and the fat on them, which is by the top of the legs, and the fat joining the liver and the kidneys, he is to take away:

⁵They are to be burned by the priest on the altar for an offering made by fire to the Lord: it is an offering for wrongdoing.

⁶Every male among the priests may have it as food in a holy place: it is most holy.

⁷As is the sin-offering, so is the offering for wrongdoing; there is one law for them: the priest who makes the offering to take away sin, he is to have it.

⁸And the priest offering any man's burned offering for him, may have the skin of the burned offering which is offered by him.

⁹And every meal offering which is cooked in the oven and everything made in a cooking pot or on a flat plate, is for the priest by whom it is offered.

¹⁰And every meal offering, mixed with oil or dry, is for all the sons of Aaron in equal measure.
