Isaiah 51
Isaiah 51 is a word spoken into exhaustion. Its hearers are a people in exile - their city in ruins, their confidence gone, their sense that God still has a future for them worn thin. The chapter does not answer that despair with empty cheer. It answers first by turning the eye backward: Hearken to me, ye that follow after righteousness… look unto the rock whence ye are hewn, and to the hole of the pit whence ye are digged (v. 1). Where did this people come from? From one man and one barren woman. Look unto Abraham your father, and unto Sarah that bare you: for I called him alone, and blessed him, and increased him (v. 2). The argument is quietly overwhelming: the God who made a nation out of a childless couple by sheer grace is not stymied by a heap of rubble.3
From that backward look the chapter turns the eye upward and outward. The LORD will comfort Zion and make her wasted places like Eden (v. 3); His salvation will go out to the isles (vv. 4-5); and then comes a promise that dwarfs every fear: the heavens shall vanish away like smoke, and the earth shall wax old like a garment… but my salvation shall be for ever, and my righteousness shall not be abolished (v. 6). The most permanent things a person can name will wear out before God's saving purpose so much as frays. So the redeemed need not fear the reproach of mortal men whose lives are themselves as fragile as grass (vv. 7-8, 12).
Twice the chapter erupts in a cry of Awake. The people cry it first to God - Awake, awake, put on strength, O arm of the LORD (v. 9) - recalling how that same arm once dried the sea so the ransomed could pass over; and the answer comes back as promise: the redeemed of the LORD shall return, and come with singing unto Zion; and everlasting joy shall be upon their head (v. 11). Then God turns the cry back on the city: Awake, awake, stand up, O Jerusalem (v. 17). And the chapter ends on its boldest image - the cup of trembling the city had drained to its dregs is taken out of her hand and put into the hand of those who afflicted her: Behold, I have taken out of thine hand the cup of trembling… thou shalt no more drink it again (v. 22).2

Isaiah 51:1-3Look Unto the Rock Whence Ye Are Hewn
1Hearken to me, ye that follow after righteousness, ye that seek the LORD: look unto the rock whence ye are hewn, and to the hole of the pit whence ye are digged. 2Look unto Abraham your father, and unto Sarah that bare you: for I called him alone, and blessed him, and increased him. 3For the LORD shall comfort Zion: he will comfort all her waste places; and he will make her wilderness like Eden, and her desert like the garden of the LORD; joy and gladness shall be found therein, thanksgiving, and the voice of melody.
The chapter opens with a summons aimed at a particular kind of listener: Hearken to me, ye that follow after righteousness, ye that seek the LORD (v. 1). These are not the careless but the weary faithful - people who are still pursuing God in a season when it is hard to see Him at work. To them the prophet gives a strange command: look unto the rock whence ye are hewn, and to the hole of the pit whence ye are digged. The image is from the quarry. A great stone block does not appear from nowhere; it is cut out of a rock face, hauled up from a pit. So look back, the LORD says, to the quarry you came from. And the next verse names it plainly: Look unto Abraham your father, and unto Sarah that bare you: for I called him alone, and blessed him, and increased him (v. 2). There is the rock and the pit - one man, one barren woman, with no nation in them at all. The whole people standing in the ruins of exile traces back to a couple who had every earthly reason to remain childless and forgotten. The point is not nostalgia. It is leverage against despair. The God who quarried a nation out of that is not finished now.3
Three short verbs in verse 2 carry the weight of the whole argument: I called him alone, and blessed him, and increased him. Notice the order. It begins with God's initiative - I called him - and the word alone presses how little Abraham brought to the transaction. He was one man, summoned out of a pagan city, with no offspring and no homeland of his own. Everything that came after - the blessing, the increase into a multitude - flowed from a call he did not earn and a grace he could only receive. For a people now reduced and scattered, this is precisely the comfort they need: their existence never rested on their numbers or their strength in the first place. It rested on a God who calls the one and makes him many. What He did with Abraham He can do again with a remnant that feels like nothing. The smallness of the present is no argument against the promise, because the promise started smaller still - with one called man and one barren woman, and a God who delights to increase.
From the backward look the verse turns to a forward promise, and the tenderness is unmistakable: For the LORD shall comfort Zion: he will comfort all her waste places (v. 3). The word comfort falls twice, and it does not mean a soothing word offered from a distance. It means active restoration - a rolling up of sleeves. The proof is in what follows: he will make her wilderness like Eden, and her desert like the garden of the LORD. The reach of this is staggering. The reversal does not stop at rebuilding a few walls; it runs all the way back to the garden. The place that has become waste will not merely be repaired - it will be made like Eden, like the very garden of the LORD, the world as it was meant to be before anything went wrong. And the result is not grim survival but song: joy and gladness shall be found therein, thanksgiving, and the voice of melody. The same wasted ground that lay silent will ring with music. This is the shape of God's comfort throughout Scripture - not a patching of the old, but a making-new that gestures all the way back to the beginning and all the way forward to the end.2
Isaiah 51:4-8My Salvation Shall Be For Ever
4Hearken unto me, my people; and give ear unto me, O my nation: for a law shall proceed from me, and I will make my judgment to rest for a light of the people. 5My righteousness is near; my salvation is gone forth, and mine arms shall judge the people; the isles shall wait upon me, and on mine arm shall they trust. 6Lift up your eyes to the heavens, and look upon the earth beneath: for the heavens shall vanish away like smoke, and the earth shall wax old like a garment, and they that dwell therein shall die in like manner: but my salvation shall be for ever, and my righteousness shall not be abolished. 7Hearken unto me, ye that know righteousness, the people in whose heart is my law; fear ye not the reproach of men, neither be ye afraid of their revilings. 8For the moth shall eat them up like a garment, and the worm shall eat them like wool: but my righteousness shall be for ever, and my salvation from generation to generation.
The summons sounds again - Hearken unto me, my people; and give ear unto me, O my nation (v. 4) - but now the horizon widens far past the borders of Israel. A law shall proceed from me, and I will make my judgment to rest for a light of the people. What God is doing with this small, battered nation is meant for the people at large; His judgment - His just ordering of things - is to become a light, and not for one nation only. Verse 5 makes the reach explicit: My righteousness is near; my salvation is gone forth, and mine arms shall judge the people; the isles shall wait upon me, and on mine arm shall they trust. The isles are the far coastlands, the distant edges of the known world. God's salvation is not a private rescue of one people from one predicament; it is a righteousness going out to the ends of the earth, drawing even the farthest peoples to wait on Him. And it is near. To exiles who feel that deliverance is impossibly distant, the word is that righteousness is already on its way and already going forth. The arm they are waiting on is the same arm the isles will learn to trust.
Then comes one of the great sentences of the book, and it is built as a deliberate contrast: Lift up your eyes to the heavens, and look upon the earth beneath: for the heavens shall vanish away like smoke, and the earth shall wax old like a garment, and they that dwell therein shall die in like manner: but my salvation shall be for ever, and my righteousness shall not be abolished (v. 6). Look up, the LORD says, at the most permanent things you can name - the sky overhead, the solid ground beneath your feet. Surely those will last. And the answer overturns the assumption: the heavens will disperse like a wisp of smoke; the earth will wear out like an old garment; even its inhabitants will pass. The two images are quietly devastating - smoke that thins into nothing, cloth that frays and is discarded. But the sentence pivots on a single word: but. My salvation shall be for ever, and my righteousness shall not be abolished. Set against a creation that has an expiry date, God's saving purpose has none. This reframes every fear the exiles carry. The empires they dread, the disgrace they feel, the ruin around them - all of it belongs to the order of things that wears out. God's salvation belongs to the order that does not.2
On that foundation the LORD presses a single application: stop being afraid of people. Hearken unto me, ye that know righteousness, the people in whose heart is my law; fear ye not the reproach of men, neither be ye afraid of their revilings (v. 7). The fear in view is not physical violence but reproach and revilings - the scorn, the mockery, the contempt of those who hold the upper hand. It is a fear that can rule a person as completely as any sword. And the antidote is a matter of proportion: For the moth shall eat them up like a garment, and the worm shall eat them like wool (v. 8). The very same image of the wearing-out garment from verse 6 returns, but now it is turned upon the mockers themselves. Their scorn feels permanent; in truth they are cloth the moth is already eating, wool the worm is already consuming. Weigh that against the refrain repeated for the third time: but my righteousness shall be for ever, and my salvation from generation to generation. The contrast is the whole argument. Why should the imperishable people of an imperishable God be governed by the opinions of those whom the moth will finish? The fear of mortal reproach shrinks to its true size only when measured against a salvation that outlasts the sky.
Isaiah 51:9-16Awake, O Arm of the LORD · The Redeemed Shall Return
9Awake, awake, put on strength, O arm of the LORD; awake, as in the ancient days, in the generations of old. Art thou not it that hath cut Rahab, and wounded the dragon? 10Art thou not it which hath dried the sea, the waters of the great deep; that hath made the depths of the sea a way for the ransomed to pass over? 11Therefore the redeemed of the LORD shall return, and come with singing unto Zion; and everlasting joy shall be upon their head: they shall obtain gladness and joy; and sorrow and mourning shall flee away. 12I, even I, am he that comforteth you: who art thou, that thou shouldest be afraid of a man that shall die, and of the son of man which shall be made as grass; 13And forgettest the LORD thy maker, that hath stretched forth the heavens, and laid the foundations of the earth; and hast feared continually every day because of the fury of the oppressor, as if he were ready to destroy? and where is the fury of the oppressor? 14The captive exile hasteneth that he may be loosed, and that he should not die in the pit, nor that his bread should fail. 15But I am the LORD thy God, that divided the sea, whose waves roared: The LORD of hosts is his name. 16And I have put my words in thy mouth, and I have covered thee in the shadow of mine hand, that I may plant the heavens, and lay the foundations of the earth, and say unto Zion, Thou art my people.
Now the people answer back, and their prayer is a cry to wake a sleeping power: Awake, awake, put on strength, O arm of the LORD; awake, as in the ancient days, in the generations of old (v. 9). The arm of the LORD is Scripture's way of speaking of God's active, saving strength. To pray awake is not to accuse God of literal sleep but to plead, out of the felt silence of exile, for that strength to act again as it visibly once did. And the prayer reaches for the oldest memories: Art thou not it that hath cut Rahab, and wounded the dragon? Art thou not it which hath dried the sea, the waters of the great deep; that hath made the depths of the sea a way for the ransomed to pass over? (vv. 9-10). Rahab and the dragon are poetic names for the great forces of chaos - and behind them, for Egypt and the Red Sea. The prayer is layering its memory: the God who tamed the roaring deep at creation is the same God who split the sea so the ransomed could walk through on dry ground at the Exodus. The logic is faith's logic - You did it then; do it now. When God seems silent, the surest prayer is often the remembering one: rehearsing back to Him the very deeds He has already done.3
The answer to that prayer arrives as one of the most luminous promises in the book: Therefore the redeemed of the LORD shall return, and come with singing unto Zion; and everlasting joy shall be upon their head: they shall obtain gladness and joy; and sorrow and mourning shall flee away (v. 11). The same arm that dried the sea for the ransomed at the Exodus will bring the redeemed home again. Hear how the verse keeps stacking joy upon joy - singing, everlasting joy, gladness and joy - as if the words can barely hold the gladness. And the picture is vivid: joy is not a passing mood but a crown, upon their head, worn openly for all to see. Then the last clause turns to what is left behind: sorrow and mourning shall flee away. They do not merely fade or lessen; they flee, routed like a defeated army. This is the homecoming of a ransomed people - not a quiet trudge back to a repaired city, but a procession of song, crowned with a gladness that does not end, with grief itself put to flight. It is a promise too large for the return from Babylon alone to exhaust, and Scripture will reach for these very words again when it describes the final wiping-away of every tear.2
God now answers the people's Awake with an I that thunders: I, even I, am he that comforteth you (v. 12). The doubling is emphatic - the Comforter is none other than the LORD Himself, in person. And on that ground He asks a question meant to shame a needless fear out into the open: who art thou, that thou shouldest be afraid of a man that shall die, and of the son of man which shall be made as grass? The oppressor who terrifies them is, when seen rightly, only a man that shall die - grass, here today and mown down tomorrow. The real failure is named in the next breath: And forgettest the LORD thy maker, that hath stretched forth the heavens, and laid the foundations of the earth (v. 13). Fear of a mortal man and forgetfulness of the immortal God are two sides of one coin. To dread the oppressor continually every day is to have shrunk God down and blown the tyrant up. So the LORD restores the true scale, ending verse 13 with a question that nearly mocks the fear: and where is the fury of the oppressor? - as if to say, look how soon it is gone. Then He plants His own name beneath their feet as bedrock: I am the LORD thy God, that divided the sea, whose waves roared: The LORD of hosts is his name (v. 15). The arm they begged to awake was never asleep; it stretched out the heavens, and it knows them by name.
Isaiah 51:17-23The Cup of Trembling Taken Out of Thine Hand
17Awake, awake, stand up, O Jerusalem, which hast drunk at the hand of the LORD the cup of his fury; thou hast drunken the dregs of the cup of trembling, and wrung them out. 18There is none to guide her among all the sons whom she hath brought forth; neither is there any that taketh her by the hand of all the sons that she hath brought up. 19These two things are come unto thee; who shall be sorry for thee? desolation, and destruction, and the famine, and the sword: by whom shall I comfort thee? 20Thy sons have fainted, they lie at the head of all the streets, as a wild bull in a net: they are full of the fury of the LORD, the rebuke of thy God. 21Therefore hear now this, thou afflicted, and drunken, but not with wine: 22Thus saith thy Lord the LORD, and thy God that pleadeth the cause of his people, Behold, I have taken out of thine hand the cup of trembling, even the dregs of the cup of my fury; thou shalt no more drink it again: 23But I will put it into the hand of them that afflict thee; which have said to thy soul, Bow down, that we may go over: and thou hast laid thy body as the ground, and as the street, to them that went over.
For the third time the cry of Awake sounds - but now God turns it back on the city herself: Awake, awake, stand up, O Jerusalem, which hast drunk at the hand of the LORD the cup of his fury; thou hast drunken the dregs of the cup of trembling, and wrung them out (v. 17). The image is of a city that has been forced to drink a cup to the very bottom. This cup is one of Scripture's recurring pictures of judgment - a draught of God's fury handed to a people to drink. And Jerusalem has drained it: not a sip, but the dregs, the bitter sediment at the bottom, wrung… out to the last drop. The cup left her reeling like a drunk in the street - not from wine, but from suffering. The verses that follow paint that staggering devastation without flinching: there is none to guide her among her own children (v. 18); desolation, and destruction, and the famine, and the sword have come (v. 19); her sons lie fainting at the head of every street, caught as a wild bull in a net (v. 20). This is honest about how bad it has been. The LORD does not pretend the cup was light. He names it as the heavy thing it was - and only then moves to take it away.
Verse 22 turns the whole chapter on a single word, and it is worth noticing who is speaking: Thus saith thy Lord the LORD, and thy God that pleadeth the cause of his people. The God who handed the cup is the same God who now pleadeth the cause of the very ones who drank it - not their accuser but their advocate. And what He declares is the great reversal: Behold, I have taken out of thine hand the cup of trembling, even the dregs of the cup of my fury; thou shalt no more drink it again. The cup is removed. The drinking is finished - no more… again. But the cup does not simply vanish; verse 23 follows it: But I will put it into the hand of them that afflict thee; which have said to thy soul, Bow down, that we may go over. The tormentors who made the city lie down in the dust and walked over her like a paved street will now drink what they made her drink. There is rough justice here, and real comfort - the suffering of God's people is not endless, and their oppressors do not escape. Yet the deepest comfort is in the first clause: the cup of fury is lifted out of the people's hand by God's own decree. They will no more drink it. The hand that gave the cup is the hand that takes it away.2
