Leviticus 13:26-28

American Standard Version

²⁶ But if the priest look on it, and, behold, there be no white hair in the bright spot, and it be no lower than the skin, but be dim; then the priest shall shut him up seven days: ²⁷ and the priest shall look upon him the seventh day: if it spread abroad in the skin, then the priest shall pronounce him unclean: it is the plague of leprosy. ²⁸ And if the bright spot stay in its place, and be not spread in the skin, but be dim; it is the rising of the burning, and the priest shall pronounce him clean: for it is the scar of the burning.
