Leviticus 22:10-12
10
"'No stranger shall eat of the holy thing: a foreigner living with the priests, or a hired servant, shall not eat of the holy thing.
11
But if a priest buys a slave, purchased by his money, he shall eat of it; and such as are born in his house, they shall eat of his bread.
12
If a priest's daughter is married to an outsider, she shall not eat of the heave offering of the holy things.
