[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 in the skin, after that he hath been seen of the priest for his cleansing, he shall be seen of the priest again: [8] And if the priest see that, behold, the scab spreadeth in the skin, then the priest shall pronounce him unclean: it is a leprosy.
