The priest will reexamine him, and if the rash has spread on the skin, the priest must pronounce him unclean; he has a skin disease. / it is a chronic skin disease and the priest must pronounce him unclean. He need not isolate him, for he is unclean. / If it spreads any further on the skin, the priest must pronounce him unclean; it is an infection.
