Jeremiah 51:25

Behold, he says, I am against thee, O mountain of perdition The mountain of perdition is to be taken in an active sense, for destroying mountain, as also a clearer explanation follows, when he says that it had destroyed all the earth For the Babylonians, as it is well known, had afflicted all their neighbors, and had transferred the imperial power of the Medes to their own city. When they subdued the Assyrians they extended their power far and wide, and at length advanced to Syria, Judea, and Egypt. Thus it happened that the Babylonians enjoyed the empire of the east till the time of Cyrus; and then the monarchy was possessed by the Persians. But our Prophet had respect to the former state of things; for he said that the Chaldeans had been like a hammer, which God had employed to break in pieces all the nations; and, according to the same meaning, he now says that all the earth had been destroyed by the Babylonians.

But God here declares that he would be their judge, because he would extend his hand over Babylon, and roll it down from the rocks, he proceeds still with the same metaphor; for as he called Babylon a mountain on account of its great buildings, and especially on account of its high walls and lofty towers, so now he adopts the same kind of language, I will cast thee down, or rather roll thee, from the rocks, and make thee a mountain of burning. He thus intimates that Babylon would become a heap of ashes, though this was not immediately fulfilled; for as we have said, it was so taken as not to be entirely laid waste. For in the time of Alexander the Great, many years after, Babylon was standing, and there Alexander died. It then follows that it was not reduced to solitude and ashes by Darius and Cyrus. But we have already untied this knot, that is, that the Prophet does not only speak of one vengeance of God, but includes others which followed. For Babylon soon after revolted and suffered a grievous punishment for its perfidy, and was then treated with great contempt. Afterwards, Seleucus tried in various ways to destroy it, and for this end Seleucia was built, and then Ctesiphon was set up in opposition to Babylon. Babylon then was by degrees reduced to that solitude of which the Prophet here speaks. Pliny says that in his time the temple of Bel was there, whom they thought to have been the founder of the city; but he afterwards adds that the other parts of the city were deserted. If Jerome, as he says, visited it, we ought; to believe what he had seen; and he says that Babylon was a small ignoble town, and ruins only were seen there. There is, then, nothing unreasonable in this prophecy, for it ought not to be restricted to one calamity only; for God ceased not in various ways to afflict Babylon until it was wholly laid waste, according to what our Prophet testifies. According to this view, then, he says that Babylon would become a mountain of burning, or a burnt mountain, for ruins only would remain; and in the same sense he immediately adds, —
