'Blacker' in the Bible

Their appearance is [now] blacker than soot [because of the prolonged famine];They are not recognized in the streets;Their skin clings to their bones;It is withered, and it has become [dry] like wood.

Yet you have not merely walked in their ways or behaved in accordance with their pagan practices; but, as if that were too little, you [soon] acted more corruptly in all your ways than they.
