Leviticus 13:1-14

ASV(i) 1 And Jehovah spake unto Moses and unto Aaron, saying, 2 When a man shall have in the skin of his flesh a rising, or a scab, or a bright spot, and it become in the skin of his flesh the plague of leprosy, then he shall be brought unto Aaron the priest, or unto one of his sons the priests: 3 and the priest shall look on the plague in the skin of the flesh: and if the hair in the plague be turned white, and the appearance of the plague be deeper than the skin of his flesh, it is the plague of leprosy; and the priest shall look on him, and pronounce him unclean. 4 And if the bright spot be white in the skin of his flesh, and the appearance thereof be not deeper than the skin, and the hair thereof be not turned white, then the priest shall shut up [him that hath] the plague seven days: 5 and the priest shall look on him the seventh day: and, behold, if in his eyes the plague be at a stay, and the plague be not spread in the skin, then the priest shall shut him up seven days more: 6 and the priest shall look on him again the seventh day; and, behold, if the plague be dim, and the plague be not spread in the skin, then the priest shall pronounce him clean: it is a scab: and he shall wash his clothes, and be clean. 7 But if the scab spread abroad in the skin, after that he hath showed himself to the priest for his cleansing, he shall show himself to the priest again: 8 and the priest shall look; and, behold, if the scab be spread in the skin, then the priest shall pronounce him unclean: it is leprosy.
9 When the plague of leprosy is in a man, then he shall be brought unto the priest; 10 and 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, 11 it 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. 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.
