Vayikra 13:20-22

Orthodox Jewish Bible

²⁰ And if, when the kohen examine it, hinei, it be in appearance deeper than the skin, and the hair thereof be turned white; the kohen shall pronounce him tamei; it is a nega tzara’at broken out of the boil.

²¹ But if the kohen examine it, and, hinei, there be no white hair therein, and if it be not deeper than the skin, but be somewhat faded, then the kohen shall quarantine him shivat yamim;

²² And if it spread much abroad in the skin, then the kohen shall pronounce him tamei; it is a nega.
