Matthew Poole and continuators on Jeremiah 46:12

12 The nations have heard of thy shame , and thy cry hath filled the land, for the mighty man hath stumbled against the mighty, and they are fallen both together .

The Prophet keepeth to his old prophetick stile, speaking of things that were to come to pass some years after, as if they were already past, because of the certainty of them, in this sense he saith other Nations had seen, because they should see the shame and confusion of the Egyptians upon their overthrow, and the cry of their slain and wounded men would fill other Lands.

For the Egyptians should certainly be overthrown, either by the Chaldeans stumbling upon the Babylonians, or the Babylonians on them, or they (flying) for haste stumbling one upon another, so as both those that went before, and those who followed after, should both fall together.
