'Rash' in the Bible

the priest is to make an examination. If the spots on the skin of the body are dull white, it is only a rash that has broken out on the skin; the person is clean.

or who is a hunchback or a dwarf, or who has an eye defect, a festering rash, scabs, or a crushed testicle.

You are not to present any animal to the Lord that is blind, injured, maimed, or has a running sore, festering rash, or scabs; you may not put any of them on the altar as a fire offering to the Lord.
