The Book of Isaiah

Chapter 21: Babylon Is Fallen

Chapter 21 gathers three 'burdens', three heavy oracles of judgment, each set at night. The first is the burden of the desert of the sea: a terrifying vision of the fall of Babylon that so shakes the prophet that his own body is racked with pain, until a watchman on the tower at last cries the words that would one day thrill every captive of God, 'Babylon is fallen, is fallen.' Then comes a short, haunting exchange out of Edom, 'Watchman, what of the night?', and finally the burden upon Arabia, where even the mighty archers of Kedar are told their glory will fail within a year. Through it all Isaiah stands as God's watchman, sleepless on the tower, telling the world what he sees.

Setting the Stage

The Vision

The Desert of the Sea

A grievous vision of Babylon's fall comes like a whirlwind, filling the prophet with pain and dread.

The Cry

Babylon Is Fallen

God sets a watchman; at last he cries the great word, "Babylon is fallen, is fallen," her idols broken.

The Question

What of the Night?

Out of Edom a voice calls to the watchman, "What of the night?" and the answer is morning, and also night.

The Burden

Arabia and Kedar

Fleeing travelers hide in the desert, and within a year the glory of proud Kedar is told it will fail.

The Vision

The Burden of the Desert of the Sea (Isaiah 21:1-4)

A terrible vision of Babylon's fall sweeps in like a desert whirlwind, and the prophet is so overwhelmed that his own body is filled with the pangs of what he sees.

Isaiah 21:1-4

A Grievous Vision

"The burden of the desert of the sea. As whirlwinds in the south pass through; so it cometh from the desert, from a terrible land. A grievous vision is declared unto me; the treacherous dealer dealeth treacherously, and the spoiler spoileth. Go up, O Elam: besiege, O Media; all the sighing thereof have I made to cease. Therefore are my loins filled with pain: pangs have taken hold upon me, as the pangs of a woman that travaileth: I was bowed down at the hearing of it; I was dismayed at the seeing of it. My heart panted, fearfulness affrighted me: the night of my pleasure hath he turned into fear unto me."

Hebrew Study

"burden," massa (מַשָּׂא). The word means both "a load lifted up" and "an utterance lifted up," a solemn, weighty oracle. It is the standard heading over Isaiah's oracles against the nations (chapters 13-23). A burden is not a light word; it is heavy freight, laid on the prophet to carry and deliver.

"the desert of the sea," midbar-yam (מִדְבַּר יָם). A striking, almost paradoxical name for Babylon, the great city set on the plain of the Euphrates, ringed by marshes and canals, "the sea." The judgment sweeps in from that wilderness like a whirlwind, unstoppable and swift.

Explanation

The oracle opens with a haunting title, "the burden of the desert of the sea," and a picture of judgment rushing in "as whirlwinds in the south pass through," sudden and irresistible, "from a terrible land." What Isaiah is shown is Babylon's fall, and the instruments are named: "Go up, O Elam: besiege, O Media", the very powers (Persia and Media) that would one day overthrow Babylon. It is a "grievous vision," a scene of treachery and plunder, "the treacherous dealer dealeth treacherously, and the spoiler spoileth." What is remarkable is the prophet's reaction. This is judgment on Israel's oppressor, yet Isaiah does not gloat. The vision tears him apart: "my loins filled with pain... pangs... as the pangs of a woman that travaileth." He is "bowed down" and "dismayed," his heart panting, "the night of my pleasure" turned into terror. To see the fall of any people, even a wicked empire, under the hand of a holy God is a fearful thing.

Gospel Focus

Notice the heart of the true prophet. Isaiah is given a word of judgment against the enemy of God's people, and instead of rejoicing he is shaken to his core, doubled over as in the pangs of childbirth. This is the spirit of God's servants in every age. Jeremiah wept over the very city he was sent to condemn. Jesus looked on Jerusalem, which would reject and kill Him, and "wept over it" (Luke 19:41). Paul carried "great heaviness and continual sorrow" in his heart for his lost kinsmen (Romans 9:2). We are not to preach judgment with a hard heart or a secret satisfaction that our enemies will fall. "Have I any pleasure at all that the wicked should die? saith the Lord GOD" (Ezekiel 18:23). If God takes no pleasure in the death of the wicked, neither should we. The warning of coming judgment should be carried the way Isaiah carried it, as a burden that breaks us, and drives us to plead with people to flee to God while there is still time.

The Cry

Babylon Is Fallen (Isaiah 21:5-10)

In the midst of Babylon's careless feasting God sets a watchman, and the watchman, standing sleepless on the tower, at last cries the great word: "Babylon is fallen, is fallen."

Isaiah 21:5-10

Set a Watchman

"Prepare the table, watch in the watchtower, eat, drink: arise, ye princes, and anoint the shield. For thus hath the Lord said unto me, Go, set a watchman, let him declare what he seeth. And he saw a chariot with a couple of horsemen, a chariot of asses, and a chariot of camels; and he hearkened diligently with much heed: And he cried, A lion: My lord, I stand continually upon the watchtower in the daytime, and I am set in my ward whole nights: And, behold, here cometh a chariot of men, with a couple of horsemen. And he answered and said, Babylon is fallen, is fallen; and all the graven images of her gods he hath broken unto the ground. O my threshing, and the corn of my floor: that which I have heard of the LORD of hosts, the God of Israel, have I declared unto you."

Hebrew Study

"watchman," tsaphah (צָפָה). One who leans out and scans the horizon, a lookout posted on the wall or tower to spot the first movement of an approaching army and sound the alarm. The prophet is God's watchman for the nations; his single duty is to "declare what he seeth."

"is fallen, is fallen," naphelah, naphelah (נָפְלָה נָפְלָה). The word is doubled for certainty and finality. Spoken here of Babylon centuries before her fall, the same twofold cry is taken up in Revelation 18:2, "Babylon the great is fallen, is fallen," over the final Babylon at the end of the age.

Explanation

Verse 5 catches Babylon in careless luxury, "Prepare the table... eat, drink", the very picture of Belshazzar's feast on the night the city fell (Daniel 5). Suddenly the alarm sounds: "arise, ye princes, and anoint the shield." Then God tells Isaiah to "set a watchman" and have him "declare what he seeth." The watchman strains at his post, watching "continually" by day and set in his ward "whole nights," until he sees the advancing column, "a chariot of men, with a couple of horsemen." And then comes the cry the whole vision has been building toward: "Babylon is fallen, is fallen; and all the graven images of her gods he hath broken unto the ground." The proud empire and her lifeless idols come crashing down together. Isaiah closes by turning to his own suffering people, threshed and crushed like grain on the threshing floor, "O my threshing, and the corn of my floor", to assure them this is a sure word: "that which I have heard of the LORD of hosts, the God of Israel, have I declared unto you."

Gospel Focus

Here is the calling of every true minister of God: to be a faithful watchman. God said to Ezekiel, "I have made thee a watchman unto the house of Israel: therefore hear the word at my mouth, and give them warning from me" (Ezekiel 3:17). The watchman does not invent the message; he reports what he sees and hears from the Lord, and he stands his post through the long night without sleeping. It is costly, lonely work, but souls depend on it. And notice the great comfort in the cry itself: "Babylon is fallen, is fallen." Babylon is the Bible's name for this world's proud, God-defying system, and its fall is certain. Revelation lifts this very cry over the last great Babylon, and adds the command, "Come out of her, my people, that ye be not partakers of her sins" (Revelation 18:2, 4). Every kingdom that exalts itself against God, along with all its idols, will be "broken unto the ground." The child of God need not fear the might of Babylon; her doom is already spoken. Our task is to keep watch, sound the warning, and keep ourselves separate from her, waiting for the sure word of the Lord to come to pass.

The Question

Watchman, What of the Night? (Isaiah 21:11-12)

A short, haunting oracle: out of Edom a voice keeps calling to the watchman for word of when the long night will end, and the answer holds both promise and warning.

Isaiah 21:11-12

The Morning Cometh, and Also the Night

"The burden of Dumah. He calleth to me out of Seir, Watchman, what of the night? Watchman, what of the night? The watchman said, The morning cometh, and also the night: if ye will enquire, enquire ye: return, come."

Hebrew Study

"Dumah," Dumah (דּוּמָה). The name means "silence" or "stillness", a fitting, ominous title for this oracle. It is linked with Seir, the mountain land of Edom (Esau's descendants), so the "silence" hints at the deathly hush that judgment brings.

"the night," laylah (לַיְלָה). Night here is a picture of the time of trouble, danger, and oppression under which Edom groans. The anxious, repeated question, "what of the night?", is the cry of people longing to know how much longer the darkness will last.

Explanation

This is one of the shortest and most mysterious oracles in Isaiah. From Seir, the land of Edom, a voice keeps calling to the watchman, urgently, twice over: "Watchman, what of the night? Watchman, what of the night?" They are desperate to know when their long night of trouble will end. The watchman's answer is deliberately double: "The morning cometh, and also the night." Yes, a morning is coming, there will be relief; but night is coming too, more darkness lies ahead. It is not a simple "all will be well." Then comes the open invitation: "if ye will enquire, enquire ye: return, come." The door is not shut. If Edom will truly seek, truly turn and come back, they are welcome to come and ask again. The answer places the burden of response squarely on the ones who asked.

Gospel Focus

"Watchman, what of the night?" is the timeless question of the human heart in its darkness, how long, and is there any hope of morning? And the answer of God's watchman still stands: "The morning cometh." For those who will turn to God there is a dawn, "Unto you that fear my name shall the Sun of righteousness arise with healing in his wings" (Malachi 4:2). Jesus Christ is the "bright and morning star" (Revelation 22:16), and "the day star" that arises in the heart (2 Peter 1:19). But the warning is just as real: "and also the night." For those who will not turn, the darkness only deepens. The decisive word is the invitation, "if ye will enquire, enquire ye: return, come." God does not force the morning on anyone. He holds the door open and says, in effect, come and ask, turn and come back. "Seek ye the LORD while he may be found, call ye upon him while he is near" (Isaiah 55:6). Whether the night ends in morning or in deeper darkness depends on whether we will heed that "return, come" while the invitation still stands.

The Burden

The Burden upon Arabia (Isaiah 21:13-17)

The last oracle turns to the desert tribes of Arabia: caravans driven into hiding, the thirsty and the fugitive met with bread and water, and a fixed date on the fall of Kedar's proud strength.

Isaiah 21:13-17

The Glory of Kedar Shall Fail

"The burden upon Arabia. In the forest in Arabia shall ye lodge, O ye travelling companies of Dedanim. The inhabitants of the land of Tema brought water to him that was thirsty, they prevented with their bread him that fled. For they fled from the swords, from the drawn sword, and from the bent bow, and from the grievousness of war. For thus hath the Lord said unto me, Within a year, according to the years of an hireling, and all the glory of Kedar shall fail: And the residue of the number of archers, the mighty men of the children of Kedar, shall be diminished: for the LORD God of Israel hath spoken it."

Hebrew Study

"prevented," qidem (קִדֵּם). In the older English of the KJV, "prevented" means "went before, met, came to meet with help", not "hindered." The people of Tema went out ahead of the fugitives to meet them with bread, an act of desert hospitality to the desperate.

"according to the years of an hireling." A hired laborer counts his term exactly and will not work a day beyond it. The phrase fixes the time precisely: within one year, to the day, measured as strictly as a hireling measures his wages, Kedar's glory would collapse.

Explanation

The final burden falls on Arabia, the proud desert tribes to the east. War is coming, and the great trading caravans, "the travelling companies of Dedanim", are driven off the roads to hide overnight in the scrub, "in the forest in Arabia shall ye lodge." The people of Tema are pictured going out to meet the fugitives with water and bread, for these are refugees, fleeing "from the drawn sword, and from the bent bow, and from the grievousness of war." Then God fixes the sentence with exact precision: "Within a year, according to the years of an hireling", one year, counted as strictly as a hired hand counts his term, "and all the glory of Kedar shall fail." Kedar was famous for its flocks and, above all, its skilled archers; but "the residue of the number of archers, the mighty men of the children of Kedar, shall be diminished." And the guarantee is the word of God Himself: "for the LORD God of Israel hath spoken it."

Gospel Focus

Kedar's boast was in its warriors, its "mighty men" and their bows. Yet God set a clock on that glory: within a year it would fail. This is the settled testimony of Scripture against all confidence in human strength: "There is no king saved by the multitude of an host: a mighty man is not delivered by much strength... An horse is a vain thing for safety" (Psalm 33:16-17). "The bows of the mighty men are broken" (1 Samuel 2:4). Every generation trusts in its "archers", its armies, its economies, its technologies, and the glory of each fails on God's appointed day. What makes it certain is not the strength of the enemy but the word of the Lord: "for the LORD God of Israel hath spoken it." When God speaks a thing, it is as good as done; "hath he said, and shall he not do it?" (Numbers 23:19). The same word that dooms proud Kedar upholds His people forever. So do not measure the future by the might of nations or the size of armies. Measure it by the word of God, for "the grass withereth, the flower fadeth: but the word of our God shall stand for ever" (Isaiah 40:8).

Chapter 21 in Review

Isaiah 21 gathers three night-time burdens under the figure of the watchman. The first, "the burden of the desert of the sea," is a vision of Babylon's fall so terrible that it fills the prophet with the pangs of childbirth; he does not gloat over the enemy's ruin but is bowed down and dismayed by it. God sets a watchman on the tower, and in the midst of Babylon's careless feasting the watchman at last cries the great word, "Babylon is fallen, is fallen; and all the graven images of her gods he hath broken unto the ground." The second burden, "Dumah," is the haunting exchange out of Edom, "Watchman, what of the night?", answered with both promise and warning: "The morning cometh, and also the night," and the open door, "if ye will enquire, enquire ye: return, come." The third, "the burden upon Arabia," sends the caravans of Dedan into hiding, meets the fugitives of Tema with bread and water, and sets a one-year clock on the fall of Kedar's proud archers, sealed by the word, "for the LORD God of Israel hath spoken it."

For the Apostolic reader the chapter presses home the calling of the watchman and the certainty of God's word. Like Ezekiel, the prophet is set as a watchman who must "declare what he seeth", faithful, sleepless, warning the people from the mouth of God, yet carrying the burden with a broken rather than a hardened heart. Above the whole chapter rings the cry "Babylon is fallen, is fallen," lifted again in Revelation over this world's proud, God-defying system, whose doom is already spoken and whose call to God's people is "Come out of her." Whether our night ends in morning or in deeper darkness turns on that quiet invitation, "return, come." And every proud strength that seems unshakable, Babylon's empire, Kedar's archers, is on a clock set by the God whose word never fails. Measure the future not by the might of nations but by the word of the Lord, which "shall stand for ever."

Key Takeaways
  • The vision of Babylon's fall broke the prophet with grief; God's watchmen warn of judgment with a broken heart, not a hard one (21:3-4; Luke 19:41).
  • God sets watchmen to "declare what he seeth", faithful, sleepless, reporting only the word of the Lord (21:6, 8; Ezekiel 3:17).
  • "Babylon is fallen, is fallen" is a certain word, lifted again over the last Babylon in Revelation 18:2 (21:9).
  • "The morning cometh, and also the night": God holds the door open, "return, come," and the outcome turns on our response (21:12; Isaiah 55:6).
  • The proud strength of Kedar was set on a one-year clock, because "the LORD God of Israel hath spoken it" (21:16-17; Isaiah 40:8).

Questions for Reflection

  • Do you carry warnings of judgment with Isaiah's broken heart, or with a secret satisfaction that your enemies will fall?
  • What would it mean for you to stand your post as a faithful "watchman" for those around you?
  • The watchman says, "return, come." Is there a place where God is holding the door open and waiting for you to turn and seek Him?
  • What "Kedar", what human strength, are you tempted to trust, and how does the sure word of God change where you place your confidence?
