Leviticus 13:25-27

New Living Translation

²⁵ the priest must examine it. If he finds that the hair in the affected area has turned white and the problem appears to be more than skin-deep, a skin disease has broken out in the burn. The priest must then pronounce the person ceremonially unclean, for it is clearly a serious skin disease. ²⁶ But if the priest finds no white hair on the affected area and the problem appears to be no more than skin-deep and has faded, the priest must quarantine the infected person for seven days. ²⁷ On the seventh day the priest must examine the person again. If the affected area has spread on the skin, the priest must pronounce that person ceremonially unclean, for it is clearly a serious skin disease.
