Leviticus

⁷But if the scab spread abroad in the skin, after that he hath shewn himself to the priest for his cleansing, he shall shew himself to the priest again: ⁸and the priest shall look, and, behold, if the scab be spread in the skin, then the priest shall pronounce him unclean: it is leprosy. ⁹When the plague of leprosy is in a man, then he shall be brought unto the priest; ¹⁰and the priest shall look, and, behold, if there be a white rising in the skin, and it have turned the hair white, and there be quick raw flesh in the rising, ¹¹it 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. ¹²And 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; ¹³then 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.
