18. “When the body has a boil on its skin, and it has healed,
19. and in the place of the boil there is a white rising, or a bright spot, reddish-white, then it shall be shown to the priest;
20. and the priest shall examine it; and behold, if its appearance is lower than the skin, and its hair has turned white, then the priest shall pronounce him unclean. It is the plague of leprosy. It has broken out in the boil.
21. But if the priest examines it, and behold, there are no white hairs in it, and it isn’t deeper than the skin, but is dim, then the priest shall isolate him seven days.
