17. and the priest shall look on him: and, behold, if the plague be turned into white, then the priest shall pronounce him clean that hath the plague: he is clean.
18. And when the flesh hath in the skin thereof a boil, and it is healed,
19. and in the place of the boil there is a white rising, or a bright spot, reddish-white, then it shall be shewed to the priest;
20. and the priest shall look, and, behold, if the appearance thereof be lower than the skin, and the hair thereof be turned white, then the priest shall pronounce him unclean: it is the plague of leprosy, it hath broken out in the boil.
