Leviticus 13:3-5

Living Bible

³ for the spot to be examined. If the hair in this spot turns white, and if the spot looks to be more than skin-deep, it is leprosy, and the priest must declare him a leper.^[a]

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.
