Leviticus 13:38

36then the priest shall examine him; and behold, if the itch has spread in the skin, the priest shall not look for the yellow hair; he is unclean.

37But if in his eyes the itch is arrested and black hair has grown in it, then the itch is healed. He is clean. The priest shall pronounce him clean.

38“When a man or a woman has bright spots in the skin of the body, even white bright spots,

39then the priest shall examine them. Behold, if the bright spots on the skin of their body are a dull white, it is a harmless rash. It has broken out in the skin. He is clean.

40“If a man’s hair has fallen from his head, he is bald. He is clean.
