▀ No man who has any defect may come near [to the priest]: no man who is blind or lame, disfigured or deformed; no man with a crippled foot or hand, or who is a hunchback or a dwarf, or who has any eye defect, or who has festering or running sores or damaged testicles. No descendant of Aaron the priest who has any defect is to come near to present the food offerings to the LORD. He has a defect; he must not come near to offer the food of his God. -
Leviticus 21:18-21 (NIV). Really. I’m not making this up.
For extra frustration, compare to Leviticus 19:14 (NIV): “Do not curse the deaf or put a stumbling block in front of the blind.”
