Leviticus 7:10-12

10Every grain offering, mixed with oil or dry, shall 1belong to all the sons of Aaron, 2to all alike.

11‘Now this is the law of the 3sacrifice of peace offerings which shall be presented to the Lord. 12If he offers it by way of 4thanksgiving, then along with the sacrifice of thanksgiving he shall offer 5unleavened cakes mixed with oil, and unleavened wafers 6spread with oil, and cakes of well stirred fine flour mixed with oil.
