Leviticus 13:4-6

Modern English Version

⁴ If the spot is white on the skin of his body, and it appears to be no deeper than the skin, and the hair is not white, then the priest shall isolate the person who has the mark for seven days. ⁵ Then the priest shall examine him on the seventh day, and if the mark is still visible, and the mark has not spread into the skin, then the priest shall isolate him for seven days more. ⁶ And the priest shall examine him again on the seventh day, and if the mark has faded and not spread into the skin, then the priest shall pronounce him clean; it is only a scab, and he shall wash his clothes and be clean.
