Leviticus 13:29-46

“If a man or woman develops a sore on the head or chin, the priest will offer a diagnosis. If it looks as if it is under the skin and the hair in it is yellow and thin, he will pronounce the person ritually unclean. It is an itch, an infectious skin disease. But if when he examines the itch, he finds it is only skin deep and there is no black hair in it, he will put the person in quarantine for seven days. On the seventh day he will reexamine the sore; if the itch has not spread, there is no yellow hair in it, and it looks as if the itch is only skin deep, the person must shave, except for the itch; the priest will send him back to quarantine for another seven days. If the itch has not spread, and looks to be only skin deep, the priest will pronounce him clean. The person can go home and wash his clothes; he is clean. But if the itch spreads after being pronounced clean, the priest must reexamine it; if the itch has spread in the skin, he doesn’t have to look any farther, for yellow hair, for instance; he is unclean. But if he sees that the itch is unchanged and black hair has begun to grow in it, the itch is healed. The person is clean and the priest will pronounce him clean. “When a man or woman gets shiny or white shiny spots on the skin, the priest is to make an examination; if the shiny spots are dull white, it is only a rash that has broken out: The person is clean. “When a man loses his hair and goes bald, he is clean. If he loses his hair from his forehead, he is bald and he is clean. But if he has a reddish-white sore on scalp or forehead, it means a serious skin disease is breaking out. The priest is to examine it; if the swollen sore on his scalp or forehead is reddish-white like the appearance of the sore of a serious skin disease, he has a serious skin disease and is unclean. The priest has to pronounce him unclean because of the sore on his head. “Any person with a serious skin disease must wear torn clothes, leave his hair loose and unbrushed, cover his upper lip, and cry out, ‘Unclean! Unclean!’ As long as anyone has the sores, that one continues to be ritually unclean. That person must live alone; he or she must live outside the camp. * * *
