Leviticus 6:14-17

14“Now this is the law of the grain offering: Aaron’s sons will present it before the Lord in front of the altar.

15The priest is to remove a handful of fine flour and olive oil from the grain offering, with all the frankincense that is on the offering, and burn its memorial portion on the altar as a pleasing aroma to the Lord.

16Aaron and his sons may eat the rest of it. It is to be eaten in the form of unleavened bread in a holy place; they are to eat it in the courtyard of the tent of meeting.

17It must not be baked with yeast; I have assigned it as their portion from my food offerings. It is especially holy, like the sin offering and the guilt offering.
