Leviticus 13:4-6

New Century Version

⁴ “If there is a white spot on a person’s skin, but the spot does not seem deeper than the skin, and if the hair from the spot has not turned white, the priest must separate that person from other people for seven days. ⁵ On the seventh day the priest must look at the person again. If he sees that the sore has not changed and it has not spread on the skin, the priest must keep the person separated for seven more days. ⁶ On the seventh day the priest must look at the person again. If the sore has faded and has not spread on the skin, the priest must announce that the person is clean. The sore is only a rash. The person must wash his clothes, and he will become clean again.
