Leviticus 21:17-21

VIN(i) 17 Say to Aaron, 'None of your seed throughout their generations who has a blemish may approach to offer the food of his God. 18 Indeed, any man in whom is a physical defect shall not come near: a blind man or lame or disfigured or deformed, 19 Or a man with broken feet or hands, 20 or who is hunchbacked or dwarfed or ulcerated in his eye or with eczema or tetter or a mashed testicle. 21 No man of the offspring of Aaron the priest who has a defect shall come near to offer the offerings of the LORD made by fire. Since he has a defect, he shall not come near to offer the bread of his God.
