Leviticus 13:29-46

“Now if a man or woman has an infection on the head or on the beard, then the priest shall look at the infection, and if it appears to be deeper than the skin and there is thin yellowish hair in it, then the priest shall pronounce him unclean; it is a scale, it is leprosy of the head or of the beard. But if the priest looks at the infection of the scale, and indeed, it appears to be no deeper than the skin and there is no black hair in it, then the priest shall isolate the person with the scaly infection for seven days. On the seventh day the priest shall look at the infection, and if the scale has not spread and no yellowish hair has grown in it, and the appearance of the scale is no deeper than the skin, then he shall shave himself, but he shall not shave the scale; and the priest shall isolate the person with the scale seven more days. Then on the seventh day the priest shall look at the scale, and if the scale has not spread in the skin and it appears to be no deeper than the skin, the priest shall pronounce him clean; and he shall wash his clothes and be clean. But if the scale spreads farther in the skin after his cleansing, then the priest shall look at him, and if the scale has spread in the skin, the priest need not seek for the yellowish hair; he is unclean. If in his sight the scale has remained, however, and black hair has grown in it, the scale has healed, he is clean; and the priest shall pronounce him clean. “When a man or a woman has bright spots on the skin of the body, even white bright spots, then the priest shall look, and if the bright spots on the skin of their bodies are a faint white, it is eczema that has broken out on the skin; he is clean. “Now if a man loses the hair of his head, he is bald; he is clean. If his head becomes bald at the front and sides, he is bald on the forehead; he is clean. But if on the bald head or the bald forehead, there occurs a reddish-white infection, it is leprosy breaking out on his bald head or on his bald forehead. Then the priest shall look at him; and if the swelling of the infection is reddish-white on his bald head or on his bald forehead, like the appearance of leprosy in the skin of the body, he is a leprous man, he is unclean. The priest shall surely pronounce him unclean; his infection is on his head. “As for the leper who has the infection, his clothes shall be torn, and the hair of his head shall be uncovered, and he shall cover his mustache and cry, ‘Unclean! Unclean!’ He shall remain unclean all the days during which he has the infection; he is unclean. He shall live alone; his dwelling shall be outside the camp.
