Leviticus 7:11-13

And this is the law of the sacrifice of peace-offerings, which one shall offer unto Jehovah. If he offer it for a thanksgiving, then he shall offer with the sacrifice of thanksgiving unleavened cakes mingled with oil, and unleavened wafers anointed with oil, and cakes mingled with oil, of fine flour soaked. With cakes of leavened bread he shall offer his oblation with the sacrifice of his peace-offerings for thanksgiving.
