Leviticus 7:8-12

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.

¹¹And this is the law for the peace-offerings offered to the Lord.

¹²If any man gives his offering as a praise-offering, then let him give with the offering, unleavened cakes mixed with oil and thin unleavened cakes covered with oil and cakes of the best meal well mixed with oil.
