Leviticus 13:10–20

¹⁰and the priest shall look on him, and behold, there is a white rising in the skin, and it hath turned the hair white, and a trace of raw flesh is in the rising: ¹¹it is an old leprosy in the skin of his flesh; and the priest shall pronounce him unclean, and he shall not shut him up, for he is unclean. ¹²But if the leprosy break out much in the skin, and the leprosy cover all the skin of him that hath the sore, from his head even to his foot, wherever the eyes of the priest look, ¹³and the priest looketh, and behold, the leprosy covereth all his flesh, he shall pronounce him clean that hath the sore; it is all turned white; he is clean. ¹⁴And on the day when raw flesh appeareth in him, he shall be unclean. ¹⁵And the priest shall look on the raw flesh, and shall pronounce him unclean: the raw flesh is unclean, it is leprosy. ¹⁶But if the raw flesh change again, and be turned white, he shall come unto the priest; ¹⁷and the priest shall look on him, and behold, the sore is turned white; then the priest shall pronounce him clean that hath the sore: he is clean.

¹⁸And the flesh—when in the skin thereof cometh a boil, and it is healed, ¹⁹and there is in the place of the boil a white rising, or a white-reddish bright spot, it shall be shewn to the priest; ²⁰and the priest shall look on it, and behold, it looketh deeper than the skin, and the hair thereof is turned white; then the priest shall pronounce him unclean: it is the sore of leprosy broken out in the boil.
