Prophetic warnings often use rich metaphors to paint a picture of upcoming events, but there comes a moment when the poetic imagery falls away to reveal the harsh reality of judgment. At this point, the prophecy shifts from symbolic language to a clear and direct explanation of the historical events about to unfold [מלבי״ם, אברבנאל]. The message turns into a sharp, uncompromising warning aimed directly at Pharaoh, the king of Egypt [מצודת דוד, אברבנאל].
The impending threat is a literal war that will soon reach him and strike a devastating blow [מצודת דוד, רד״ק]. The approaching sword represents an actual military invasion led by Nebuchadnezzar, the king of Babylon. This attack will catch Pharaoh in a vulnerable position while he is outside the borders of his own land. It is there that the Babylonian forces will strike, destroying his armies [מלבי״ם]. Furthermore, this massive assault will not be carried out by Babylon alone. A vast coalition of many kings and commanders will join forces with the Babylonian king to bring total ruin upon Egypt [אברבנאל].
