Leviticus 13:40-50

40“A man who has lost his hair and is bald is clean. 41If he has lost his hair from the front of his scalp and has a bald forehead, he is clean. 42But if he has a reddish-white sore on his bald head or forehead, it is a defiling disease breaking out on his head or forehead. 43The priest is to examine him, and if the swollen sore on his head or forehead is reddish-white like a defiling skin disease,

44the man is diseased and is unclean. The priest shall pronounce him unclean because of the sore on his head. 45“Anyone with such a defiling disease must wear torn clothes, let their hair be unkempt, Or clothes, uncover their head cover the lower part of their face and cry out, ‘Unclean! Unclean!’

46As long as they have the disease they remain unclean. They must live alone; they must live outside the camp.

Regulations About Defiling Molds 47“As for any fabric that is spoiled with a defiling mold—any woolen or linen clothing, 48any woven or knitted material of linen or wool, any leather or anything made of leather— 49if the affected area in the fabric, the leather, the woven or knitted material, or any leather article, is greenish or reddish, it is a defiling mold and must be shown to the priest. 50The priest is to examine the affected area and isolate the article for seven days.
