Leviticus 22:10-13
22:10 “‘No lay person may eat anything holy. Neither a priest’s lodger nor a hired laborer may eat anything holy,
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.
