Leviticus 22:2-3, 11-13

“Speak to Aaron and his sons, that they separate themselves from the holy things of the children of Israel, and that they do not profane My holy name by what they dedicate to Me: I am the LORD. Say to them: ‘Whoever of all your descendants throughout your generations, who goes near the holy things which the children of Israel dedicate to the LORD, while he has uncleanness upon him, that person shall be cut off from My presence: I am the LORD.

But if the priest buys a person with his money, he may eat it; and one who is born in his house may eat his food. If the priest’s daughter is married to an outsider, she may not eat of the holy offerings. But if the priest’s daughter is a widow or divorced, and has no child, and has returned to her father’s house as in her youth, she may eat her father’s food; but no outsider shall eat it.
