Leviticus 13:23

²¹But if the priest look, and behold there is no white hair on it, and it be not below the skin of the flesh, and it be dark-colored; then the priest shall separate him seven days.

²²But if it manifestly spread over the skin, then the priest shall pronounce him unclean: it is a plague of leprosy; it has broken out in the ulcer.

— Leviticus 13:23 —

²⁴And if the flesh be in his skin in a state of fiery inflammation, and there should be in his skin the part which is healed of the inflammation, bright, clear, and white, suffused with red or very white;

²⁵then the priest shall look upon him, and, behold, if the hair being white is changed to a bright color, and its appearance is lower than the skin, it is a leprosy; it has broken out in the inflammation, and the priest shall pronounce him unclean: it is a plague of leprosy.
