Leviticus 7:11-14

11‘Now this is the law of the sacrifice of peace offerings which shall be presented to the Lord:

12If one offers it as a sacrificial meal of thanksgiving, then along with the sacrifice of thanksgiving he shall offer unleavened cakes mixed with oil, and unleavened wafers spread with oil, and cakes of fine flour mixed with oil.

13With the sacrifice of his peace offerings for thanksgiving, he shall present his offering with cakes of leavened bread.

14Of this he shall present one [cake] from each offering as a contribution to the Lord; it shall belong to the priest who sprinkles the blood of the peace offerings.
