Leviticus 21:17-21

“Speak to Aaron, saying, ‘None of your descendants throughout their generations who has an impairment shall approach to offer the food of his God.

For no one who has an impairment shall approach: a man who is blind, or one who limps, or one who has a slit nose, or one with any conspicuous feature,

or someone who has a broken foot or broken hand,

or a contorted back, or one who is a dwarf, or has a spot in his eye, or a festering rash or scabs, or crushed testicles.

No man among the descendants of Aaron the priest who has an impairment is to come forward to offer the Lord’s offerings by fire; since he has an impairment, he shall not come forward to offer the food of his God.
