5 Prepare the table, Set a watchman in the tower, Eat and drink. Arise, you princes, Anoint the shield! 6 For thus has the Lord said to me: "Go, set a watchman, Let him declare what he sees." 7 And he saw a chariot with a pair of horsemen, A chariot of donkeys, and a chariot of camels, And he listened earnestly with great care. 8 Then he cried, "A lion, my Lord! I stand continually on the watchtower in the daytime; I have sat at my post every night. 9 And look, here comes a chariot of men with a pair of horsemen!" Then he answered and said, "Babylon is fallen, is fallen! And all the carved images of her gods He has broken to the ground."
Matthew Henry's Commentary on Isaiah 21:5-9
Commentary on Isaiah 21:1-10
(Read Isaiah 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.
