JPS_ASV_Byz(i) 19 and in the place of the boil there is a white rising, or a bright spot, reddish-white, then it shall be shown 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.
