²⁹ If an ish or isha have a nega upon the head or the chin,

³⁰ Then the kohen shall examine the nega, and, hinei, if it be in appearance deeper than the skin, and there be in it a yellow thin hair, then the kohen shall pronounce him tamei; it is a scale, even a tzara’at upon the head or chin.

³¹ And if the kohen examine the nega of the scale, and, hinei, it be not in appearance deeper than the skin, and that there is no black hair in it, then the kohen shall quarantine him that hath the nega of the scale shivat yamim;
