And after the Lord had given Moses and Aaron instructions about the purification of women after childbirth, He continued His words to them saying:
"When anyone among you has a swelling, a rash, or a bright spot upon their skin that may become an infectious disease, they must be brought to Aaron the priest, or to one of his sons who are priests. The priest shall examine the sore, and if the hair in it has turned white and the sore appears deeper than the skin, it is a diseased infection. When the priest sees it, he shall declare that person unclean.
But if the bright spot is white on the skin and does not appear deeper, and the hair within has not turned white, then the priest shall isolate that person for seven days. On the seventh day he shall examine them again. If the sore remains the same and has not spread, the priest shall keep them isolated for another seven days. If, at the second examination, the sore has faded and has not spread, then it is only a surface rash. The priest shall pronounce that person clean—it was but a rash. They shall wash their clothes, and they shall be clean.
But if the rash spreads further after being shown to the priest, then they must be examined again. If it has indeed spread, the priest shall declare them unclean—it is a disease.
When a man is afflicted with such a disease, he shall be brought before the priest. If the priest sees a white swelling on the skin with hair turned white, and there is raw flesh in the swelling, it is a chronic disease of the skin. The priest shall declare him unclean. He shall not be isolated, for he is already unclean.
But if the disease has spread across the skin and covered the whole body from head to toe, and has all turned white, as long as the priest sees that it is everywhere, he shall pronounce the person clean as it is a sign, that the person has been healed or the disease, has ran its course . Yet whenever raw flesh appears, they are unclean. When the raw flesh changes and turns white again, they must come to the priest, and the priest shall declare them clean.
When a boil appears in someone's skin and it heals, but a white swelling or reddish-white spot appears where the boil was, it must be shown to the priest. If he sees that it looks deeper than the skin and the hair has turned white, he shall declare the person unclean—it is an infection that has broken out in the boil. But if there is no white hair and it does not appear deeper, then the priest shall isolate the person for seven days. If it has spread, he shall declare them unclean. If it does not spread, it is only a scar from the boil, and the priest shall declare them clean.
When the skin is burned and the raw flesh of the burn becomes a reddish-white or white spot, the priest shall examine it. If the hair has turned white and the spot seems deeper than the skin, it is an infection—it has broken out in the burn. The priest shall declare that person unclean. But if the hair has not turned white and the spot is not deeper, he shall isolate them for seven days. If it spreads, he shall declare them unclean. But if it does not spread, it is only a scar from the burn, and the priest shall declare them clean.
When a sore or ulcer appears on the head or chin, the priest shall examine it. If it looks deeper than the skin and the hair within is yellow and thin, it is an infection, and the priest shall declare that person unclean. But if it does not seem deeper and the hair within is black, then it is only a surface rash, and the priest shall isolate them for seven days. If, after the seven days, it has not spread, then the person shall shave around it but not the sore itself. The priest shall isolate them for another seven days. If the sore has not spread and does not seem deeper, the priest shall declare them clean. They shall wash their clothes and be clean. But if it spreads, the priest shall declare them unclean.
When a man or a woman has white spots on the skin, the priest shall examine them. If the spots are dull white, it is only a harmless rash, and they are clean.
When a man loses his hair and becomes bald, he is clean. If he loses hair only on the forehead, he is bald but clean. But if a reddish-white sore appears on the bald head or forehead, it is a disease breaking out. The priest shall examine it, and if it is reddish-white, then it is a spreading disease, and the priest shall declare that person unclean—it is upon the bald head.
Anyone with such a disease must wear torn clothes, leave their hair unkempt, cover the lower part of their face, and cry out, 'Unclean! Unclean!' As long as they have the disease, they remain unclean. They must live alone; their dwelling must be outside the camp."
