Leviticus 13:31-33

New Living Translation

³¹ If the priest examines the scabby sore and finds that it is only skin-deep but there is no black hair on it, he must quarantine the person for seven days. ³² On the seventh day the priest must examine the sore again. If he finds that the scabby sore has not spread, and there is no yellow hair on it, and it appears to be only skin-deep, ³³ the person must shave off all hair except the hair on the affected area. Then the priest must quarantine the person for another seven days.
