Leviticus 21:7-8, 23

“ ‘They must not marry women defiled by prostitution or divorced from their husbands, because priests are holy to their God. Regard them as holy, because they offer up the food of your God. Consider them holy, because I the LORD am holy—I who make you holy.

yet because of his defect, he must not go near the curtain or approach the altar, and so desecrate my sanctuary. I am the LORD, who makes them holy.’ ”
