Leviticus 22:2, 3, 11-13

“Tell Aaron and his sons to treat with respect the sacred offerings the Israelites consecrate to me, so they will not profane my holy name. I am the LORD.

“Say to them: ‘For the generations to come, if any of your descendants is ceremonially unclean and yet comes near the sacred offerings that the Israelites consecrate to the LORD, that person must be cut off from my presence. I am the LORD.

But if a priest buys a slave with money, or if slaves are born in his household, they may eat his food. If a priest’s daughter marries anyone other than a priest, she may not eat any of the sacred contributions. But if a priest’s daughter becomes a widow or is divorced, yet has no children, and she returns to live in her father’s household as in her youth, she may eat her father’s food. No unauthorized person, however, may eat it.
