Leviticus 13:20-22

21st Century King James Version

²⁰ and if, when the priest seeth it, behold, it is in appearance lower than the skin and the hair thereof is turned white, the priest shall pronounce him unclean; it is a plague of leprosy broken out of the boil.

²¹ But if the priest look on it, and behold, there are no white hairs therein and if it is not lower than the skin, but is somewhat dark, then the priest shall shut him up seven days.

²² And if it spread much abroad in the skin, then the priest shall pronounce him unclean; it is a plague.
