Leviticus 13:34-36

New International Version - UK

³⁴ On the seventh day the priest is to examine the sore, and if it has not spread in the skin and appears to be no more than skin deep, the priest shall pronounce them clean. They must wash their clothes, and they will be clean. ³⁵ But if the sore does spread in the skin after they are pronounced clean, ³⁶ the priest is to examine them, and if he finds that the sore has spread in the skin, he does not need to look for yellow hair; they are unclean.
