Leviticus 21:17-23

17“Speak to Aaron, saying: ‘No man of your descendants in succeeding generations, who has any defect, may approach to offer the bread of his God.

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.

22He may eat the bread of his God, both the most holy and the holy;

23only he shall not go near the veil or approach the altar, because he has a defect, lest he profane My sanctuaries; for I the Lord sanctify them.’ ”
