Leviticus 7:11-15

‘This is the law of the sacrifice of peace offerings which he shall offer to the LORD: If he offers it for a thanksgiving, then he shall offer, with the sacrifice of thanksgiving, unleavened cakes mixed with oil, unleavened wafers anointed with oil, or cakes of blended flour mixed with oil. Besides the cakes, as his offering he shall offer leavened bread with the sacrifice of thanksgiving of his peace offering. And from it he shall offer one cake from each offering as a heave offering to the LORD. It shall belong to the priest who sprinkles the blood of the peace offering. ‘The flesh of the sacrifice of his peace offering for thanksgiving shall be eaten the same day it is offered. He shall not leave any of it until morning.
