Leviticus 13:20

¹⁸The flesh also, in which, even in the skin thereof, was a boil, and is healed,

¹⁹And in the place of the boil there be a white rising, or a bright spot, white, and somewhat reddish, and it be shewed to the priest;

— Leviticus 13:20 —

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

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