Leviticus 13:21-23

Complete Jewish Bible

²¹ But if the cohen looks at it and doesn’t see any white hairs in it, and it isn’t more than skin-deep but appears faded, the cohen is to isolate him for seven days. ²² If it spreads on the skin, the cohen is to declare him unclean; it is the disease. ²³ But if the bright spot stays where it was and has not spread, it is the scar of the boil; and the cohen is to declare him clean.
