And, behold, here cometh, etc. Our translators make the words those of the watchman. But they are better taken as the prophet's statement of a fact, "And behold, just then there cometh a troop of men, riding two and two"—the sign for which he was to watch (Isaiah 21:7), or rather the first part of it.
We must suppose the rest of the sign to follow, and the watchman then to listen awhile attentively. Suddenly he hears the sound of a sacked town, and he exclaims, Babylon is fallen, is fallen, etc. All the graven images of her gods he hath broken unto the ground.
Recent documents, belonging to the time of Cyrus, and treating of his capture of Babylon, show that this expression is not to be understood literally. Cyrus was not an iconoclast; he did not break into pieces, or in any way destroy or insult the Babylonian idols.
On the contrary, he maintained them in their several shrines, or restored them where they had been displaced; he professed himself a worshipper of the chief Babylonian gods—Bel, Nebo, and Merodach—he repaired the temple of Merodach; he prayed to Bel and Nebo to lengthen his days; he caused his son, Cambyses, to take part in the great religious ceremony wherewith the Babylonians opened the new year.
Thus his conquest of Babylon did not bring upon its gods a physical, but only a moral, destruction. The Persian victory discredited and degraded them. It proclaimed to Western Asia that the idolatrous system so long prevalent in the region between Mount Zagros and the Mediterranean was no longer in the ascendant, but lay at the mercy of another quite different religion, which condescended to accord it toleration.
Such was the permanent result. No doubt there was also, in the sack of the city, much damage done to many of the idols by a greedy soldiery, who may have carried off many images of gold or silver, and broken up others that were not portable, and stripped off the plates of precious metal from the idols of "brass, and iron, and wood, and stone" (Daniel 5:6).
