18. If anyone has a boil that has healed
19. and if afterwards a white swelling or a reddish-white spot appears where the boil was, he shall go to the priest.
20. The priest shall examine him, and if the spot seems to be deeper than the surrounding skin and the hairs in it have turned white, he shall pronounce him unclean. It is a dreaded skin disease that has started in the boil.
21. But if the priest examines it and finds that the hairs in it have not turned white and that it is not deeper than the surrounding skin, but is light in colour, the priest shall isolate him for seven days.
22. If the spot spreads, the priest shall pronounce him unclean; he is diseased.
