Leviticus 21:16–23
16 And the Lord said to Moses, 17 “Say to Aaron, None of your descendants throughout their generations who has a blemish may approach to offer the bread of his God. 18 For no one who has a blemish shall draw near, a man blind or lame, or one who has a mutilated face or a limb too long, 19 or a man who has an injured foot or an injured hand, 20 or a hunchback, or a dwarf, or a man with a defect in his sight or an itching disease or scabs or crushed testicles; 21 no man of the descendants of Aaron the priest who has a blemish shall come near to offer the Lord’s offerings by fire; since he has a blemish, he shall not come near to offer the bread of his God. 22 He may eat the bread of his God, both of the most holy and of the holy things, 23 but he shall not come near the veil or approach the altar, because he has a blemish, that he may not profane my sanctuaries; for I am the Lord who sanctify them.”
