Leviticus 21:16-23

16Adonai spoke to Moses saying:

17“Say to Aaron: None of your offspring throughout their generations who has a defect may approach to offer the food of his God.

18Any man who has a defect is not to draw near: no one blind or lame or disfigured or deformed,

19or a man who has a crippled foot or crippled hand

20or a hunchback or dwarf, or who has an eye defect or a rash or scabs, or who has damaged testicles.

21None of the offspring of Aaron the kohen who has a defect shall come near to present the offerings of Adonai made by fire. Since he has a defect, he is not to come near to offer the food of his God.

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

23But he is not to approach the curtain or come near the altar, because of the defect on him, so that he may not desecrate My sanctuaries, for I am Adonai who sanctifies them.”
