4 But if the bright spot is white on the skin of his body, and it does not appear to be deeper than the skin, and the hair on it has not turned white, then the priest shall isolate him who has the infection for seven days. 5 The priest shall look at him on the seventh day, and if in his eyes the infection has not changed and the infection has not spread on the skin, then the priest shall isolate him for seven more days. 6 The priest shall look at him again on the seventh day, and if the infection has faded and the mark has not spread on the skin, then the priest shall pronounce him clean; it is only a scab. And he shall wash his clothes and be clean. 7 “But if the scab spreads farther on the skin after he has shown himself to the priest for his cleansing, he shall appear again to the priest. 8 The priest shall look, and if the scab has spread on the skin, then the priest shall pronounce him unclean; it is leprosy.
