Leviticus 13:25-27

21st Century King James Version

²⁵ then the priest shall look upon it; and behold, if the hair in the bright spot is turned white and it is in appearance deeper than the skin, it is a leprosy broken out of the burning. Therefore the priest shall pronounce him unclean; it is the plague of leprosy.

²⁶ But if the priest look on it, and behold, there is no white hair in the bright spot and it is no lower than the other skin, but is somewhat dark, then the priest shall shut him up seven days.

²⁷ And the priest shall look upon him the seventh day; and if it is spread much abroad in the skin, then the priest shall pronounce him unclean; it is the plague of leprosy.
