Leviticus 22:2-3, 11-13

Speak unto Aaron and to his sons, that they separate themselves from the holy things of the children of Israel, and that they profane not my holy name in those things which they hallow unto me: I am the LORD. Say unto them, Whosoever he be of all your seed among your generations, that goeth unto the holy things, which the children of Israel hallow unto the LORD, having his uncleanness upon him, that soul shall be cut off from my presence: I am the LORD.

But if the priest buy any soul with his money, he shall eat of it, and he that is born in his house: they shall eat of his meat. If the priest's daughter also be married unto a stranger, she may not eat of an offering of the holy things. But if the priest's daughter be a widow, or divorced, and have no child, and is returned unto her father's house, as in her youth, she shall eat of her father's meat: but there shall no stranger eat thereof.
