Leviticus 21:18-21

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

19or has a broken foot or arm,

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

21No 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.
