Leviticus 13:9-17

9When the plague of leprosy is in a man, then he shall be brought to the priest; 10And the priest shall see him : and, behold, if the swelling is white in the skin, and it hath turned the hair white, and there is living raw flesh in the swelling;1 11It is an old leprosy in the skin of his flesh, and the priest shall pronounce him unclean, and shall not shut him up: for he is unclean. 12And if a leprosy shall break out in the skin, and the leprosy shall cover all the skin of him that hath the plague from his head even to his foot, wherever the priest looketh; 13Then the priest shall consider: and, behold, if the leprosy hath covered all his flesh, he shall pronounce him clean that hath the plague: it is all turned white: he is clean. 14But when raw flesh appeareth in him, he shall be unclean. 15And the priest shall see the raw flesh, and pronounce him to be unclean: for the raw flesh is unclean: it is a leprosy. 16Or if the raw flesh shall turn again, and be changed into white, he shall come to the priest; 17And the priest shall see him: and, behold, if the plague is turned into white; then the priest shall pronounce him clean that hath the plague: he is clean.
