Leviticus 6:14-17

14And this is the law of the meal offering: the sons of Aaron shall offer it before the LORD, before the altar.

15And he shall take up therefrom his handful, of the fine flour of the meal offering, and of the oil thereof, and all the frankincense which is upon the meal offering, and shall burn it upon the altar for a sweet savour, as the memorial thereof, unto the LORD.

16And that which is left thereof shall Aaron and his sons eat: it shall be eaten without leaven in a holy place; in the court of the tent of meeting they shall eat it.

17It shall not be baken with leaven. I have given it as their portion of my offerings made by fire; it is most holy, as the sin offering, and as the guilt offering.
