Thematic Bible: Debarred sons of aaron from exercise of priestly offices

"Tell Aaron: None of your descendants throughout your generations who has a physical defect is to come near to present the food of his God. No man who has any defect is to come near: no man who is blind, lame, facially disfigured, or deformed; no man who has a broken foot or hand, read more.
or who is a hunchback or a dwarf, or who has an eye defect, a festering rash, scabs, or a crushed testicle. No descendant of Aaron the priest who has a defect is to come near to present the fire offerings to the Lord. He has a defect and is not to come near to present the food of his God. He may eat the food of his God from what is especially holy as well as from what is holy. But because he has a defect, he must not go near the curtain or approach the altar. He is not to desecrate My sanctuaries, for I am the Lord who sets them apart."
