Leviticus 13:25-27

Darby Translation

²⁵ and the priest look on it, and behold, the hair is turned white in the bright spot, and it looketh deeper than the skin, it is a leprosy which is broken out in the inflammation; and the priest shall pronounce him unclean: it is the sore 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 deeper than the skin, and is pale, the priest shall shut him up seven days.

²⁷ And the priest shall look on him the seventh day, and if it have spread much in the skin, the priest shall pronounce him unclean: it is the sore of leprosy.
