Leviticus 13:8

And the priest shall look , and if the eruption has spread in the skin , then the priest shall pronounce him unclean ; it is a leprous disease .

The priest is to examine that person, and if the rash has spread in the skin, he shall pronounce them unclean; it is a defiling skin disease.

And if the priest see that, behold, the scab spreadeth in the skin, then the priest shall pronounce him unclean : it is a leprosy.
