Lev 13:6 And the priest shall examine him again on the seventh day, and if the diseased area has faded and the disease has not spread in the skin, then the priest shall pronounce him clean; it is only an eruption. And he shall wash his clothes and be clean.
Lev 13:7 But if the eruption spreads in the skin, after he has shown himself to the priest for his cleansing, he shall appear again before the priest.
Lev 13:8 And the priest shall look, and if the eruption has spread in the skin, then the priest shall pronounce him unclean; it is a leprous disease.
