21 But if the priest considers it and there appear to be no white hairs in it and it is not lower than the skin, but somewhat dark, then the priest shall shut him up seven days;
22 and if it spreads much abroad in the skin, then the priest shall pronounce him unclean: it is a plague.
23 But if the bright spot stays in its place and does not spread, it is the scab of a boil; and the priest shall pronounce him clean.
24 Likewise when the flesh has in its skin a burn from fire, and in the place healed from the burn there a white bright spot, somewhat reddish, or white,
25 then the priest shall look upon it; and if the hair in the bright spot is turned white and it looks deeper than the skin, it is a leprosy broken out of the burn; and the priest shall pronounce him unclean; it is the plague of leprosy.
26 But if the priest looks on it and there is no white hair in the bright spot and it is no lower than the other skin, but dark, then the priest shall shut him up seven days;
27 and the priest shall recognize it 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.
