Leviticus 13:6-8

6And the priestH3548 shall look on him again the seventhH7637 dayH3117, and behold, the sore is become pale and the sore hath not spreadH6581 in the skinH5785, then the priestH3548 shall pronounce him cleanH2891; it is a scab; and he shall washH3526 his garmentsH899 and be cleanH2891.

7But if the scab have spreadH6581 much in the skinH5785, after that he hath been seenH7200 by the priestH3548 for his cleansing, he shall be seenH7200 by the priestH3548 again;

8and the priestH3548 shall look on him, and behold, the scab hath spreadH6581 in the skinH5785; then the priestH3548 shall pronounce him uncleanH2930: it is leprosy.
