ירמיהו, פרק נ׳, פסוק מ״א

The impending downfall of the Babylonian empire is painted as a dramatic reversal of fortune, brought about by a massive military coalition gathering against it. The prophet deliberately uses the exact language once employed to predict Babylon's own invasion of the Land of Israel. Now, the tables have turned, and that earlier prophecy of doom is flipped and directed squarely at Babylon itself [מלבי״ם].

This invading force is identified as arriving from the north, specifically pointing to the empires of Media and Persia, which were geographically situated to Babylon's northeast [מצודת דוד]. They are depicted as awakening from a slumber, rising vigorously to take military action [מצודת ציון]. Furthermore, their armies will march from the very edges of the earth, traveling from incredibly distant countries to reach the battlefield [מצודת דוד, ביאור שטיינזלץ].

At the head of this vast military campaign are royal figures, though commentators offer different perspectives on their exact nature. One approach suggests that the description of these leaders emphasizes their greatness and prestige rather than their sheer number. In this view, the focus is on a few highly significant monarchs, specifically pointing to Darius, king of Media, and Cyrus, king of Persia [מצודת דוד, רד״ק, אברבנאל]. Conversely, another perspective takes the description literally, understanding it as a reference to a massive quantity of rulers. According to this explanation, numerous kings from various other nations joined the campaign, bringing their own forces to assist the armies of Media and Persia in their war [רד״ק, מלבי״ם].
