Leviticus 6:14-18

“ ‘These are the regulations for the grain offering: Aaron’s sons are to bring it before the LORD, in front of the altar. The priest is to take a handful of the finest flour and some olive oil, together with all the incense on the grain offering, and burn the memorial portion on the altar as an aroma pleasing to the LORD. Aaron and his sons shall eat the rest of it, but it is to be eaten without yeast in the sanctuary area; they are to eat it in the courtyard of the tent of meeting. It must not be baked with yeast; I have given it as their share of the food offerings presented to me. Like the sin offering and the guilt offering, it is most holy. Any male descendant of Aaron may eat it. For all generations to come it is his perpetual share of the food offerings presented to the LORD. Whatever touches them will become holy.’ ”
