Leviticus 13:11-13

American Standard Version

¹¹ it is an old leprosy in the skin of his flesh, and the priest shall pronounce him unclean: he shall not shut him up; for he is unclean. ¹² And if the leprosy break out abroad in the skin, and the leprosy cover all the skin of him that hath the plague from his head even to his feet, as far as appeareth to the priest; ¹³ then the priest shall look; and, behold, if the leprosy have covered all his flesh, he shall pronounce him clean that hath the plague: it is all turned white: he is clean.
