Leviticus 13:6-8

Living Bible

⁶ Again on the seventh day the priest will examine him, and if the marks of the disease have become fainter and have not spread, then the priest shall pronounce him cured; it was only a scab, and the man need only wash his clothes and everything will be normal again. ⁷ But if the spot spreads in the skin after he has come to the priest to be examined, he must come back to the priest again, ⁸ and the priest shall look again, and if the spot has spread, then the priest must pronounce him a leper.
