Leviticus 13:4-8 - A Bright Spot On The Skin
4 If the bright spot is white in the skin of his body, and its appearance isn't deeper than the skin, and its hair hasn't turned white, then the priest shall isolate the infected person for seven days. 5 The priest shall examine him on the seventh day, and, behold, if in his eyes the plague is arrested, and the plague hasn't spread in the skin, then the priest shall isolate him for seven more days. 6 The priest shall examine him again on the seventh day; and behold, if the plague has faded, and the plague hasn't spread in the skin, then the priest shall pronounce him clean. It is a scab. He shall wash his clothes, and be clean. 7 But if the scab spreads on the skin, after he has shown himself to the priest for his cleansing, he shall show himself to the priest again. 8 The priest shall examine him; and behold, if the scab has spread on the skin, then the priest shall pronounce him unclean. It is leprosy.
