Leviticus 7:11-12 ASV
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.
