The priest is to examine the skin rash on the body. If the hair on the skin rash has turned white and its appearance is deeper than the skin of his body, it's an infectious skin disease. When the priest has examined it, then he is to declare him unclean.

But if the priest has examined it and the infection has faded after it has been washed, he is to tear it out of the garment or the leather or the warp or the woof.
