Leviticus 22:9-11

⁹They shall therefore keep My charge, lest they bear sin for it, and die therein, if they profane it: I am the LORD who sanctify them.

¹⁰There shall no common man eat of the holy thing; a tenant of a priest, or a hired servant, shall not eat of the holy thing.

¹¹But if a priest buy any soul, the purchase of his money, he may eat of it; and such as are born in his house, they may eat of his bread.
