Leviticus 13:20-22

Darby Translation

²⁰ and the priest shall look on it, and behold, it looketh deeper than the skin, and the hair thereof is turned white; then the priest shall pronounce him unclean: it is the sore of leprosy broken out in the boil.

²¹ But if the priest look on it, and behold, there are no white hairs therein, and it is not deeper than the skin, and is pale, the priest shall shut him up seven days;

²² and if it spread much in the skin, then the priest shall pronounce him unclean: it is the sore.
