Leviticus 21:16

12 He must not leave or desecrate the sanctuary of his God, for the consecration of the anointing oil of his God is on him. I am the LORD.

13 The woman he marries must be a virgin.

14 He is not to marry a widow, a divorced woman, or one defiled by prostitution. He is to marry a virgin from his own people,

15 so that he does not defile his offspring among his people, for I am the LORD who sanctifies him.”

16 Then the LORD said to Moses,

17 “Say to Aaron, ‘For the generations to come, none of your descendants who has a physical defect may approach to offer the food of his God.

18 No man who has any defect may approach—no man who is blind, lame, disfigured, or deformed;

19 no man who has a broken foot or hand,

20 or who is a hunchback or dwarf, or who has an eye defect, a festering rash, scabs, or a crushed testicle.
