Leviticus 6:16; Leviticus 6:17

16 'What is left of it Aaron and his sons are to eat. It shall be eaten as unleavened cakes in a holy place; they are to eat it in the court of the tent of meeting.

17 'It shall not be baked with leaven. I have given it as their share from My offerings by fire; it is most holy, like the sin offering and the guilt offering.
