Leviticus 22:2-3, 11-13

“Tell Aaron and his sons to be careful with the holy gifts of the sons of Israel, which they dedicate to Me, so as not to profane My holy name; I am the LORD. Say to them, ‘If any man among all your descendants throughout your generations approaches the holy gifts which the sons of Israel dedicate to the LORD, while he has an uncleanness, that person shall be cut off from before Me; I am the LORD.

But if a priest buys a slave as his property with his money, that one may eat of it, and those who are born in his house may eat of his food. If a priest’s daughter is married to a layman, she shall not eat of the offering of the gifts. But if a priest’s daughter becomes a widow or divorced, and has no child and returns to her father’s house as in her youth, she shall eat of her father’s food; but no layman shall eat of it.
