Leviticus 21:16-24

16Then the Lord spoke to Moses, saying,

17“Say to Aaron, ‘Throughout their generations none of your descendants who has any [physical] defect shall approach [the altar] to present the food of his God.

18For no man who has a defect shall approach [God’s altar as a priest]: no man who is blind or lame, or who has a disfigured face, or any deformed limb,

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

20or a hunchback or a dwarf, or one who has a defect in his eye or eczema or scabs or crushed testicles.

21No man among the descendants of Aaron the priest who has a [physical] defect and is disfigured or deformed is to approach [the altar] to present the offerings of the Lord by fire. He has a defect; he shall not approach [the altar] to present the food of his God.

22He may eat the food of his God, both of the most holy and of the holy things,

23but he shall not go within the veil or approach the altar [of incense], because he has a defect, so that he will not profane My sanctuaries; for I am the Lord who sanctifies them.’ ”

24So Moses spoke to Aaron and to his sons, and to all the Israelites.
