Leviticus 13:12-14

American Standard Version

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. ¹⁴ But whensoever raw flesh appeareth in him, he shall be unclean.
