Leviticus 13:2-8

Thomson(i) 2 If any man hath, on the outer coat of the skin, a remarkable swelling, very white, and there be a touch of the leprosy on the outer coat of his skin, he shall be brought to Aaron the priest, or to one of his sons, the priests: 3 and the priest shall look at the touch on the outer coat of his skin; and if the hair in the touch be turned white, and the appearance of the touch be deeper than the outer skin, it is a touch of the leprosy. And when the priest shall see this, he shall pronounce him unclean. 4 But though the whiteness be exceedingly bright on the outer coat of the skin, if the appearance of it be not deeper than the outer coat, and the hair thereof be not turned white, but is of a duskish colour; the priest shall set apart the patient seven day. 5 And on the seventh day the priest shall view the touch; and if the touch still remaineth before him, but hath not spread on the outer skin, the priest shall set him apart seven days more. 6 And on the seventh day the priest shall look on him again, and if the touch be languid, and hath not spread on the outer skin, the priest shall pronounce him clean; for it is but a mark. And having washed his clothes, he shall be clean. 7 But if the mark on the outer skin shall change, and spread, after the priest viewed him for the purpose of pronouncing him clean, he shall again appear before the priest, 8 and the priest shall view him; and if the mark hath spread on the skin, the priest shall pronounce him unclean. It is a leprosy.
