Leviticus 21:18-21
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.
