They shall fall down slain in the land of the Chaldeans, and wounded in her streets.
HE proceeds with what we began yesterday to explain, — that the time was nigh when God would take vengeance on the Babylonians. As, then, this could not be without great destruction in a city so very populous, and as it could not be overthrown except calamity extended itself through the whole country, hence, he says, that though Babylon should prepare great and powerful armies...
Babylon was once a golden cup in the Lord's hand, filled with His favor, but also His battle-axe to break nations. Those that carry all before them a great while will yet meet their match; even Babylon's day will come, and it too shall fall.
