Leviticus 13:5-7

21st Century King James Version

⁵ And the priest shall look on him the seventh day; and behold, if the plague in its appearance is stayed and the plague spread not in the skin, then the priest shall shut him up seven days more.

⁶ And the priest shall look on him again the seventh day; and behold, if the plague be somewhat dark and the plague spread not in the skin, the priest shall pronounce him clean. It is but a scab, and he shall wash his clothes and be clean.

⁷ But if the scab spread much abroad in the skin, after he hath been seen by the priest for his cleansing, he shall be seen by the priest again.
