¹⁵ The prophet Jeremiah also foretold the fall of Babylon, which would take place many years later. And he included an interesting detail: “There is a devastation upon her waters, and they must be dried up.

Jeremiah 50:38;

16. When was Babylon conquered, and by whom?

¹⁶ In 539 B.C.E., the time of Babylon’s rule as the preeminent world power came to an end when the vigorous Persian ruler Cyrus, accompanied by the army of Media, marched against the city. What Cyrus found, however, was formidable. Babylon was surrounded by huge walls and seemed impregnable. The great river Euphrates, too, ran through the city and made an important contribution to its defenses.

17, 18. (a) In what way was there “a devastation upon [Babylon’s] waters”? (b) Why did Babylon’s ‘mighty men cease to fight’?

¹⁷ The Greek historian Herodotus describes how Cyrus handled the problem: “He placed a portion of his army at the point where the river enters the city, and another body at the back of the place where it issues forth, with orders to march into the town by the bed of the stream, as soon as the water became shallow enough . . . He turned the Euphrates by a canal into the basin [an artificial lake dug by a previous ruler of Babylon], which was then a marsh, on which the river sank to such an extent that the natural bed of the stream became fordable. Hereupon the Persians who had been left for the purpose at Babylon by the river-side, entered the stream, which had now sunk so as to reach about midway up a man’s thigh, and thus got into the town.”​⁴

¹⁸ In this way the city fell, as Jeremiah and Isaiah had warned. But notice the detailed fulfillment of prophecy. There was literally ‘a devastation upon her waters, and they were dried up.’ It was the lowering of the waters of the Euphrates that enabled Cyrus to gain access to the city.
