Leviticus 13:29-46

“When a man or woman has a disease on the head or in the beard (face), the priest shall examine the diseased place; if it appears to be deeper than the skin, with yellow, thin hair in it, the priest shall pronounce him unclean; it is a scale, it is leprosy of the head or beard. But if the priest examines the spot infected by the scale, and it does not appear deeper than the skin and there is no black hair in it, the priest shall isolate the person with the scaly infection for seven days. On the seventh day the priest shall examine the diseased spot; if the scale has not spread and has no yellow hair in it, and the scale does not look 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 for seven more days. Then on the seventh day the priest shall look at the scale; if the scale has not spread on the skin and appears to be no deeper than the skin, the priest shall pronounce him clean; he shall wash his clothes and be clean. But if the scale spreads farther on the skin after his cleansing, then the priest shall examine him, and if the scale has spread on the skin, the priest need not look for the yellowish hair; he is unclean. If, in the priest’s estimation, the scale has remained [without spreading], and black hair has grown in it, the scale is 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 is a dull white, it is [only] a rash that has broken out on the skin; he is clean. “If a man loses the hair on his head, he is bald, but he is clean. And if he loses the hair on front of his head, he is bald on the forehead, but he is clean. But if there is a reddish-white infection on the bald head or forehead, it is leprosy breaking out on his bald head or forehead. Then the priest shall examine him, and if the diseased swelling is reddish-white on his bald head or forehead like the appearance of leprosy on the skin of the body, he is a leprous man; he is unclean; the priest shall most certainly pronounce him unclean; his disease 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 (disheveled), and he shall cover his mustache and call out, ‘Unclean! Unclean!’ He shall remain [ceremonially] unclean as long as the disease is on him; he is unclean. He shall live alone; he shall live outside the camp.
