And, behold, here cometh a chariot of men, with a couple of horsemen. And {m} he answered and said, Babylon is fallen, is fallen; and all the graven images of her gods he hath broken to the ground.

(m) The watchman whom Isaiah set up, told him who came toward Babylon, and the angel declared that it would be destroyed: all this was done in a vision.

Wesley's Notes

21:9 Men - Not fitted with goods, but provided with men to fight. He - The prophet, who here gives an explication of the vision. He - God, by the hands of Cyrus.

Jamieson-Fausset-Brown Bible Commentary

9. chariot of men-chariots with men in them; or rather, the same body of riders, horsemen two abreast, as in Isa 21:7 [Maurer]. But Horsley, "The man drawn in a car with a pair of riders." The first half of this verse describes what the watchman sees; the second half, what the watchman says, in consequence of what he sees. In the interval between Isa 21:7 and Isa 21:9, the overthrow of Babylon by the horsemen, or man in the car, is accomplished. The overthrow needed to be announced to the prophet by the watchman, owing to the great extent of the city. Herodotus (1.131) says that one part of the city was captured some time before the other received the tidings of it.

answered-not to something said previously, but in reference to the subject in the mind of the writer, to be collected from the preceding discourse: proclaimeth (Job 3:2, Margin; Da 2:26; Ac 5:8).

fallen . fallen-The repetition expresses emphasis and certainty (Ps 92:9; 93:3; compare Jer 51:8; Re 18:2).

images-Bel, Merodach, &c. (Jer 50:2; 51:44, 52). The Persians had no images, temples, or altars, and charged the makers of such with madness [Herodotus 1.131]; therefore they dashed the Babylonian "images broken unto the ground."

Matthew Henry's Concise Commentary

21:1-10 Babylon was a flat country, abundantly watered. The destruction of Babylon, so often prophesied of by Isaiah, was typical of the destruction of the great foe of the New Testament church, foretold in the Revelation. To the poor oppressed captives it would be welcome news; to the proud oppressors it would be grievous. Let this check vain mirth and sensual pleasures, that we know not in what heaviness the mirth may end. Here is the alarm given to Babylon, when forced by Cyrus. An ass and a camel seem to be the symbols of the Medes and Persians. Babylon's idols shall be so far from protecting her, that they shall be broken down. True believers are the corn of God's floor; hypocrites are but as chaff and straw, with which the wheat is now mixed, but from which it shall be separated. The corn of God's floor must expect to be threshed by afflictions and persecutions. God's Israel of old was afflicted. Even then God owns it is his still. In all events concerning the church, past, present, and to come, we must look to God, who has power to do any thing for his church, and grace to do every thing that is for her good.
