Leviticus 13:45-48

“If a person has a skin disease that spreads, he must warn other people by shouting, ‘Unclean, unclean!’ His clothes must be torn at the seams, he must let his hair stay uncombed, and he must cover his mouth. That person will be unclean the whole time he has the disease; he is unclean. He must live alone outside the camp. “Clothing might have mildew on it. It might be clothing made of linen or wool (either woven or knitted), or of leather, or something made from leather.
