Scab

““When someone has a swelling or rash or bright spot on his skin that could become an infectious skin disease, he must be brought to Aaron the priest or to one of his sons who is a priest.”

“The priest will examine him again on the seventh day, and if the sore has faded and has not spread on the skin, the priest shall pronounce him clean; it is a rash. The person must wash his clothes and be clean.”

“and for a swelling, rash, or spot,”

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

“You are not to present to the LORD any animal that is blind, injured, or maimed, or anything with a running sore, a festering rash, or a scab; you must not put any of these on the altar as an offering made by fire to the LORD.”

“The LORD will afflict you with the boils of Egypt, with tumors and scabs and itch from which you cannot be cured.”

“the Lord will bring sores on the heads of the daughters of Zion, and the LORD will make their foreheads bare.””
