Leviticus 13:12-17

12If the leprosy breaks out farther on the skin, and the leprosy covers all the skin of the person who has the infection from his head even to his feet, 1as far as the priest can see, 13then the priest shall look, and behold, if the leprosy has covered his entire 2body, he shall pronounce the one who has the infection clean; it has all turned white and he is clean. 14But whenever raw flesh appears on him, he shall be unclean. 15The priest shall look at the raw flesh, and he shall pronounce him unclean; the raw flesh is unclean, it is leprosy. 16Or if the raw flesh turns back and is changed to white, then he shall 3come to the priest, 17and the priest shall look at him, and behold, if the infected area has turned white, then the priest shall pronounce the one who has the infection clean; he is clean.
