Leviticus 13:29-46

“When a man or woman has a condition on the head or chin, the priest is to examine the condition. If it appears to be deeper than the skin,  and the hair in it is yellow and sparse, the priest must pronounce the person unclean. It is a scaly outbreak, a serious skin disease of the head or chin. When the priest examines the scaly condition, if it does not appear to be deeper than the skin, and there is no black hair in it, the priest will quarantine the person with the scaly condition for seven days. The priest will reexamine the condition on the seventh day. If the scaly outbreak has not spread and there is no yellow hair in it and it does not appear to be deeper than the skin, the person is to shave himself  but not shave the scaly area. Then the priest will quarantine the person who has the scaly outbreak for another seven days. The priest will examine the scaly outbreak on the seventh day, and if it has not spread on the skin and does not appear to be deeper than the skin, the priest is to pronounce the person clean. He is to wash his clothes, and he will be clean. But if the scaly outbreak spreads further on the skin after his cleansing, the priest is to examine the person. If the scaly outbreak has spread on the skin, the priest does not need to look for yellow hair; the person is unclean. But if as far as he can see, the scaly outbreak remains unchanged and black hair has grown in it, then it has healed; he is clean. The priest is to pronounce the person clean. “When a man or a woman has white spots on the skin of the body, the priest is to make an examination. If the spots on the skin of the body are dull white, it is only a rash  that has broken out on the skin; the person is clean. “If a man loses the hair of his head, he is bald,  but he is clean. Or if he loses the hair at his hairline, he is bald on his forehead, but he is clean. But if there is a reddish-white condition on the bald head or forehead, it is a serious skin disease breaking out on his head or forehead.  The priest is to examine him, and if the swelling of the condition on his bald head or forehead is reddish-white, like the appearance of a serious skin disease on his body, the man is afflicted with a serious skin disease;  he is unclean. The priest must pronounce him unclean; the infection is on his head. “The person who has a case of serious skin disease is to have his clothes torn  and his hair hanging loose, and he must cover his mouth  and cry out, ‘Unclean, unclean! ’ He will remain unclean as long as he has the disease; he is unclean. He must live alone in a place outside the camp.
