LEV 13:20

20 and when the priest seeth the place of the leprosy (to be) lower than the other flesh, and the hairs turned into whiteness, the priest shall defoul him, that is, (shall) deem him (to be) foul, (or the priest shall pronounce him to be defiled, or unclean); for the wound of leprosy is bred in the botch [[or for a plague of leprosy is sprung in the botch]].
