Leviticus 6:16, 18, 20, 26

What is left of it Aaron and his sons are to eat. It shall be eaten as unleavened bread in a holy place; they are to eat it in the courtyard of the Tent of Meeting. [1 Cor 9:13, 14]

Every male among the sons of Aaron may eat it [as his share]; it is a permanent ordinance throughout your generations, from offerings by fire to the LORD. Whatever touches them will become consecrated (ceremonially clean).’ ”

“This is the offering which Aaron and his sons are to present to the LORD on the day when he is anointed: the tenth of an ephah of fine flour as a regular grain offering, half of it in the morning and half of it in the evening.

The priest who offers it for sin shall eat it. It shall be eaten in a holy place, in the courtyard of the Tent of Meeting.
