Leviticus 21:17-21

17“Tell Aaron: If any of your descendants (now or in future generations) has a physical defect, he must never bring food to offer to God.

18Indeed, no one who has a physical defect may ever come near ⌞the altar⌟. That means anyone who is blind or lame, who has a disfigured face, a deformity,

19or a crippled hand or foot,

20who is a hunchback or dwarf, who has defective sight, skin diseases, or crushed testicles.

21If a descendant of the priest Aaron has a physical defect, he must never bring sacrifices by fire to the Lord. He has a defect. He must never bring food to offer to God.
