Leviticus 6:14-17

14Now this is the law of the grain offering: Aaron’s sons shall present it before the LORD in front of the altar. 15The priest is to remove a handful of fine flour and olive oil, together with all the frankincense from the grain offering, and burn the memorial portion on the altar as a pleasing aroma to the LORD.

16Aaron and his sons are to eat the remainder. It must be eaten without leaven in a holy place; they are to eat it in the courtyard of the Tent of Meeting. 17It must not be baked with leaven; I have assigned it as their portion of My food offerings. It is most holy, like the sin offering and the guilt offering.
