Leviticus 13
5 and the priest shall look on him the seventh day: and, behold, if in his eyes the plague be at a stay, and the plague be not spread in the skin, then the priest shall shut him up seven days more:
6 Ref and the priest shall look on him again the seventh day; and, behold, if the plague be dim, and the plague be not spread in the skin, then the priest shall pronounce him clean: it is a scab: and he shall wash his clothes, and be clean.
