4-8"If the shiny spot on the skin is white but appears to be only on the surface and the hair has not turned white, the priest will quarantine the person for seven days. On the seventh day the priest will examine it again; if, in his judgment, the sore is the same and has not spread, the priest will keep him in quarantine for another seven days. On the seventh day the priest will examine him a second time; if the sore has faded and hasn't spread, the priest will declare him clean—it is a harmless rash. The person can go home and wash his clothes; he is clean. But if the sore spreads after he has shown himself to the priest and been declared clean, he must come back again to the priest who will conduct another examination. If the sore has spread, the priest will pronounce him unclean—it is a serious skin disease and infectious.
9-17"Whenever someone has a serious and infectious skin disease, you must bring him to the priest. The priest will examine him; if there is a white swelling in the skin, the hair is turning white, and there is an open sore in the swelling, it is a chronic skin disease. The priest will pronounce him unclean. But he doesn't need to quarantine him because he's already given his diagnosis of unclean. If a serious disease breaks out that covers all the skin from head to foot, wherever the priest looks, the priest will make a thorough examination; if the disease covers his entire body, he will pronounce the person with the sore clean—since it has turned all white, he is clean. But if they are open, running sores, he is unclean. The priest will examine the open sores and pronounce him unclean. The open sores are unclean; they are evidence of a serious skin disease. But if the open sores dry up and turn white, he is to come back to the priest who will reexamine him; if the sores have turned white, the priest will pronounce the person with the sores clean. He is clean.
