Leviticus 21:17-24

21:17 “Tell Aaron, ‘No man from your descendants throughout their generations who has a physical flaw is to approach to present the food of his God. 21:18 Certainly no man who has a physical flaw is to approach: a blind man, or one who is lame, or one with a slit nose, or a limb too long, 21:19 or a man who has had a broken leg or arm, 21:20 or a hunchback, or a dwarf, or one with a spot in his eye, or a festering eruption, or a feverish rash, or a crushed testicle. 21:21 No man from the descendants of Aaron the priest who has a physical flaw may step forward to present the Lord’s gifts; he has a physical flaw, so he must not step forward to present the food of his God. 21:22 He may eat both the most holy and the holy food of his God, 21:23 but he must not go into the veil-canopy or step forward to the altar because he has a physical flaw. Thus he must not profane my holy places, for I am the Lord who sanctifies them.’”

21:24 So Moses spoke these things to Aaron, his sons, and all the Israelites.
