Jeremiah 50:23

How is the hammer of the whole earth cut asunder and broken! how is Babylon become a desolation among the nations!

The hammer image identifies Babylon as the power that had struck across the whole earth. Its being cut asunder and broken means that hammer-power would be cut down and shattered. In that shattering Babylon would be left broken and made a desolation among the nations. The verse therefore foretells the fall of Babylon.
