Leviticus 6:14-17

14‘This is the law of the grain offering: The sons of Aaron shall offer it on the altar before the Lord.

15He shall take from it his handful of the fine flour of the grain offering, with its oil, and all the frankincense which is on the grain offering, and shall burn it on the altar for a sweet aroma, as a memorial to the Lord.

16And the remainder of it Aaron and his sons shall eat; with unleavened bread it shall be eaten in a holy place; in the court of the tabernacle of meeting they shall eat it.

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