Leviticus 13:25

then the priest shall examine it; and behold, if the hair in the bright spot has turned white, and its appearance is deeper than the skin, it is leprosy. It has broken out in the burning, and the priest shall pronounce him unclean. It is the plague of leprosy.

Then the priest shall look upon it: and, behold, if the hair in the bright spot be turned white, and it be in sight deeper than the skin; it is a leprosy broken out of the burning: wherefore the priest shall pronounce him unclean: it is the plague of leprosy.
