Leviticus 13:6-8

Darby Translation

⁶ And the priest shall look on him again the seventh day, and behold, the sore is become pale and the sore hath not spread in the skin, then the priest shall pronounce him clean; it is a scab; and he shall wash his garments and be clean.

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

⁸ and the priest shall look on him, and behold, the scab hath spread in the skin; then the priest shall pronounce him unclean: it is leprosy.
