Leviticus 13:19-21

New Catholic Bible

¹⁹ and then a whitish-red bump or spot appears where the boil was, he shall show it to the priest. ²⁰ The priest shall examine it. If he sees that it is deeper than the skin and the hair has turned white, then the priest shall declare him to be unclean. It is a leprous sore that has broken out from the boil. ²¹ But if the priest, upon examining it, sees that it does not have white hair and it is not deeper than the skin, but rather it is a bit darker, then the priest shall quarantine him for seven days.
