利未記 13:6

第七天，祭司要再察看他，若災病發暗，而且沒有在皮上發散，祭司要定他為潔淨，原來是癬；那人就要洗衣服，得為潔淨。

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.
