Leviticus 13:35-37

Complete Jewish Bible

³⁵ But if the crusted area spreads after his purification, ³⁶ then the cohen is to examine him; and if he sees that the crusted area has spread on the skin, the cohen is not to look for yellow hair; he is unclean. ³⁷ But if the crusted area’s appearance doesn’t change, and black hair grows up in it, then the crusted area is healed; he is clean; and the cohen is to declare him clean.
