Leviticus 21:18-21

ISV(i) 18 Indeed, any person who has a defect is not to approach the Tent of Meeting— the blind, the lame, one who is mutilated in the face or who has a very long limb, 19 or a person who has a fractured foot or hand, 20 has scoliosis, is a dwarf, or has an eye defect, an itching disease, scabs, or a crushed testicle. 21 None of the descendants of Aaron the priest who has a defect is to approach to bring offerings of the LORD made by fire, since he has a defect. He is not to approach to offer the food of his God.
