Leviticus 13:35-37

New Catholic Bible

³⁵ But if the scab spreads after his cleansing, ³⁶ the priest shall examine him. If the scab has spread, the priest need not look for yellow hair. He is unclean. ³⁷ But if, from his viewpoint, the scab has not grown larger and black hair has grown upon it, then the scab is clean. The priest shall declare him clean.
