Leviticus 21:18-21

CLV(i) 18 For no man at all who has a blemish in him may approach:a blind man or one lame or disfigured or deformed 19 or a man in whom there is a crippled foot or a crippled hand 20 or who is hunchbacked or dwarfed or ulcerated in his eye or with eczema or tetter or a mashed testicle. 21 Any man of the seed of Aaron the priest, in whom there is a blemish, shall not come close to bring near the fire offerings of Yahweh. Since a blemish is in him, he shall not come close to bring near the bread of his Elohim.
