Leviticus 22:2-3

22:2 “Tell Aaron and his sons that they must deal respectfully with the holy offerings of the Israelites, which they consecrate to me, so that they do not profane my holy name. I am the Lord. 22:3 Say to them, ‘Throughout your generations, if any man from all your descendants approaches the holy offerings which the Israelites consecrate to the Lord while he is impure, that person must be cut off from before me. I am the Lord.

Leviticus 22:11-13

22:11 but if a priest buys a person with his own money, that person may eat the holy offerings, and those born in the priest’s own house may eat his food. 22:12 If a priest’s daughter marries a lay person, she may not eat the holy contribution offerings, 22:13 but if a priest’s daughter is a widow or divorced, and she has no children so that she returns to live in her father’s house as in her youth, she may eat from her father’s food, but no lay person may eat it.
