Leviticus 6:15-16

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 savor, as the memorial thereof, unto Jehovah. 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.
