Leviticus 13:4-6

Living Bible

⁴ “But if the white spot in the skin does not seem to be deeper than the skin and the hair in the spot has not turned white, the priest shall quarantine him for seven days. ⁵ At the end of that time, on the seventh day, the priest will examine him again, and if the spot has not changed and has not spread in the skin, then the priest must quarantine him seven days more. 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.
