By 616 B.C., Nabopolassar had ruled Babylon for a decade. He had spent those ten years profitably, rebelling against the Assyrians and successfully expelling their forces from Babylonia. Civil wars between major Assyrian cities and the general decrepitude of the empire confirmed his belief that the time had come to transfer the seat of Mesopotamian power from Nineveh to Babylon. Gathering his own Chaldean army, along with allies from Media, Persia, Cimmeria and Scythia, Nabopolassar marched on the capital city of Nineveh in May of 612 B.C.
Resistance was fierce, but they took the city within three months. What Nabopolassar probably didn’t know was that a Judean prophet had accurately describe his sacking of Nineveh as many as thirty years prior to it. Still less did the king of Babylon understand that he was doing the work of Judah’s God when he went about his business.
