Leviticus 6:16-18

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.

18Any male among Aaron’s descendants may eat it. It is a permanent portion throughout your generations from the food offerings to the Lord. Anything that touches the offerings will become holy.”
