Leviticus 13:15-17

American Standard Version

¹⁵ And the priest shall look on the raw flesh, and pronounce him unclean: the raw flesh is unclean: it is leprosy. ¹⁶ Or if the raw flesh turn again, and be changed unto white, then he shall come unto the priest; ¹⁷ and the priest shall look on him; and, behold, if the plague be turned into white, then the priest shall pronounce him clean that hath the plague: he is clean.
