Leviticus 6:16-18

16Aaron and his sons are to eat what is left over from it. It must be eaten unleavened in a holy place; they are to eat it in the courtyard of the Meeting Tent.

17It must not be baked with yeast. I have given it as their portion from my gifts. It is most holy, like the sin offering and the guilt offering.

18Every male among the sons of Aaron may eat it. It is a perpetual allotted portion throughout your generations from the gifts of the Lord. Anyone who touches these gifts must be holy.’”
