Leviticus 21:18-21

18For any man who has a defect shall not approach: a man blind or lame, who has a marred face or any limb too long,

19a man who has a broken foot or broken hand,

20or is a hunchback or a dwarf, or a man who has a defect in his eye, or eczema or scab, or is a eunuch.

21No man of the descendants of Aaron the priest, who has a defect, shall come near to offer the offerings made by fire to the Lord. He has a defect; he shall not come near to offer the bread of his God.
