Leviticus 21:17-21

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.

18Certainly 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,

19or a man who has had a broken leg or arm,

20or 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.

21No 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.
