Leviticus 21:15-21 New Living Translation (NLT)

15. so that he will not dishonor his descendants among his clan, for I am the lord who makes him holy.”

16. Then the lord said to Moses,

17. “Give the following instructions to Aaron: In all future generations, none of your descendants who has any defect will qualify to offer food to his God.

18. No one who has a defect qualifies, whether he is blind, lame, disfigured, deformed,

19. or has a broken foot or arm,

20. or is hunchbacked or dwarfed, or has a defective eye, or skin sores or scabs, or damaged testicles.

21. No descendant of Aaron who has a defect may approach the altar to present special gifts to the lord. Since he has a defect, he may not approach the altar to offer food to his God.
