Isaiah 51

Introduction

Isaiah 51 belongs to the heart of Second Isaiah (chapters 40--55), the great sequence of comfort and hope addressed to the exiles in Babylon. The chapter is structured around a series of urgent calls to listen and awake. In the first half (vv. 1--8), God summons his faithful remnant to remember their origins in Abraham and Sarah, to trust in the coming restoration of Zion, and to refuse to fear mortal oppressors. In the second half (vv. 9--23), the voice shifts: first the people cry out for God's mighty arm to awake as in the days of the Exodus (vv. 9--11), then God responds with assurance (vv. 12--16), and finally Jerusalem herself is summoned to awake from the stupor of divine judgment, because the cup of wrath is being taken from her hand and given to her tormentors (vv. 17--23).

The chapter is rich with creation and Exodus imagery interwoven together. The mythic figures of Rahab and the dragon (v. 9) recall both the chaos-waters of creation and the historical parting of the sea. The wilderness becoming "like Eden" (v. 3) reverses the curse of Genesis. And the repeated refrain -- "my righteousness" and "my salvation" -- underscores that Israel's redemption is rooted not in her own merit but in the faithfulness of the God who called Abraham when he was only one. This chapter prepares the way for the Servant's suffering in Isaiah 52:13--Isaiah 53:12 by establishing that God's arm, once bared at the Exodus, is about to act again in an even greater deliverance.

Look to the Rock: The Example of Abraham (vv. 1--3)

1 "Listen to Me, you who pursue righteousness, you who seek the LORD: Look to the rock from which you were cut, and to the quarry from which you were hewn. 2 Look to Abraham your father, and to Sarah who gave you birth. When I called him, he was but one; then I blessed him and multiplied him. 3 For the LORD will comfort Zion and will look with compassion on all her ruins; He will make her wilderness like Eden and her desert like the garden of the LORD. Joy and gladness will be found in her, thanksgiving and melodious song.

1 "Listen to me, you who pursue righteousness, you who seek the LORD: Look to the rock from which you were quarried, and to the hollow of the pit from which you were dug out. 2 Look to Abraham your father, and to Sarah who bore you. For when he was only one I called him, and I blessed him, and I made him many. 3 For the LORD has comforted Zion; he has comforted all her ruins. He has made her wilderness like Eden and her wasteland like the garden of the LORD. Joy and gladness will be found in her, thanksgiving and the sound of song.

Notes

The chapter opens with the first of three "listen to me" summons (vv. 1, 4, 7), each addressing the faithful remnant who still seek the LORD in the midst of exile. The phrase רֹדְפֵי צֶדֶק ("pursuers of righteousness") does not mean those who have achieved righteousness but those who are actively striving after it -- a hopeful designation for exiles who might wonder whether God has abandoned them.

The metaphor of the "rock" (צוּר) and "quarry" (מַקֶּבֶת בּוֹר, literally "the hollow of the pit") is striking. The exiles are told to look back to their origin. Just as a stone comes from a single quarry, so all Israel was hewn from one man -- Abraham. The verb חֻצַּבְתֶּם ("you were quarried/hewn") emphasizes that God shaped his people from raw material, as a stonemason cuts rock. Some commentators see an echo of Deuteronomy 32:18 ("the Rock who bore you").

Verse 2 identifies the rock and quarry explicitly: Abraham and Sarah. The emphasis falls on אֶחָד ("one") -- Abraham was solitary, a single individual without descendants, when God called him. Yet God וַאֲבָרְכֵהוּ וְאַרְבֵּהוּ ("blessed him and made him many"). The implication for the exiles is powerful: if God could create a nation from one lonely man, he can surely restore a scattered remnant. The verb תְּחוֹלֶלְכֶם ("who bore you," from חול, to writhe in labor) applied to Sarah emphasizes the painful, miraculous nature of Israel's birth through a barren woman (Genesis 18:10-14).

Verse 3 shifts from past to future. The key verb נִחַם ("comfort") is the same root that opens this entire section of Isaiah: "Comfort, comfort my people" (Isaiah 40:1). The perfect tense here ("has comforted") expresses prophetic certainty -- the comfort is so sure it can be spoken of as already accomplished. The wilderness will become כְּעֵדֶן ("like Eden"), reversing the desolation of exile with the language of paradise itself. The pairing of שָׂשׂוֹן וְשִׂמְחָה ("joy and gladness") with תּוֹדָה וְקוֹל זִמְרָה ("thanksgiving and the sound of song") anticipates the great processional return described in Isaiah 55:12.

God's Justice as a Light to the Nations (vv. 4--6)

4 Pay attention to Me, My people, and listen to Me, My nation; for a law will go out from Me, and My justice will become a light to the nations; I will bring it about quickly. 5 My righteousness draws near, My salvation is on the way, and My arms will bring justice to the nations. The islands will look for Me and wait in hope for My arm. 6 Lift up your eyes to the heavens, and look at the earth below; for the heavens will vanish like smoke, the earth will wear out like a garment, and its people will die like gnats. But My salvation will last forever, and My righteousness will never fail.

4 Pay attention to me, my people, and give ear to me, my nation; for instruction will go out from me, and my justice I will set as a light to the peoples -- in a moment. 5 My righteousness is near; my salvation has gone forth, and my arms will judge the peoples. The coastlands will wait for me, and for my arm they will hope. 6 Lift up your eyes to the heavens, and look at the earth beneath; for the heavens will dissipate like smoke, and the earth will wear out like a garment, and those who dwell in it will die like gnats. But my salvation will endure forever, and my righteousness will never be broken.

Notes

The second summons (v. 4) introduces a universalist theme: God's תּוֹרָה ("instruction" or "law") will go forth not only to Israel but as לְאוֹר עַמִּים ("a light to the peoples"). This echoes the Servant's mission in Isaiah 42:6 ("a light to the nations") and Isaiah 49:6. The word אַרְגִּיעַ ("in a moment" or "quickly") is from a root meaning to settle or bring rest; it conveys the idea that God will establish his justice swiftly and decisively.

Verse 5 continues the theme with striking urgency: קָרוֹב צִדְקִי ("my righteousness is near"). The "arm" (זְרוֹעַ) of the LORD, which will become central in verse 9, appears here as the instrument of both salvation and judgment. The אִיִּים ("islands" or "coastlands") represent the farthest reaches of the known world -- the distant maritime peoples of the Mediterranean and beyond. Even they will look to God's arm with hope, a remarkable claim of universal scope.

Verse 6 establishes a breathtaking contrast between the transience of the created order and the permanence of God's salvation. The heavens will נִמְלָחוּ ("dissipate" or "be dispersed") like smoke -- a rare verb whose exact meaning is debated; it may carry overtones of "tearing apart" or "dissolving." The earth will תִּבְלֶה ("wear out") like a garment, and its inhabitants will die כְּמוֹ כֵן -- the meaning of this phrase is disputed. Some render it "like gnats" (reading כֵּן as a gnat or louse, as in Exodus 8:16-17); others read "in like manner" (i.e., they will likewise perish). The contrast is clear regardless: heaven and earth are perishable, but God's יְשׁוּעָה ("salvation") and צִדְקָה ("righteousness") are eternal. Jesus echoes this very idea in Matthew 24:35: "Heaven and earth will pass away, but my words will never pass away." The apostle Peter draws on similar imagery in 2 Peter 3:10-13.

Interpretations

The relationship between the passing away of heaven and earth (v. 6) and the eternal endurance of God's salvation has been understood differently:

Do Not Fear Human Reproach (vv. 7--8)

7 Listen to Me, you who know what is right, you people with My law in your hearts: Do not fear the scorn of men; do not be broken by their insults. 8 For the moth will devour them like a garment, and the worm will eat them like wool. But My righteousness will last forever, My salvation through all generations."

7 Listen to me, you who know righteousness, the people in whose heart is my instruction: Do not fear the reproach of mortals, and do not be dismayed by their reviling. 8 For the moth will eat them like a garment, and the grub will eat them like wool. But my righteousness will endure forever, and my salvation to all generations."

Notes

The third "listen to me" (v. 7) narrows the address to those who already possess inward knowledge of God: יֹדְעֵי צֶדֶק ("those who know righteousness") and עַם תּוֹרָתִי בְּלִבָּם ("a people in whose heart is my instruction"). This language anticipates the new covenant promise of Jeremiah 31:33, where God writes his law on human hearts. The exiles who have internalized God's teaching are told not to fear חֶרְפַּת אֱנוֹשׁ ("the reproach of mortals") -- the taunts and insults of their Babylonian captors.

The reason for fearlessness is given in verse 8: the persecutors themselves are perishable. עָשׁ ("moth") and סָס ("grub" or "clothes-moth larva") will consume them as they consume fabric. The imagery deliberately echoes verse 6 -- garments wear out, and so will mortal oppressors. The refrain וְצִדְקָתִי לְעוֹלָם תִּהְיֶה ("my righteousness will endure forever") is repeated verbatim from verse 6, creating a structural bracket around this unit (vv. 4--8) and driving home the contrast between what is temporary and what is eternal.

Awake, O Arm of the LORD (vv. 9--11)

9 Awake, awake, put on strength, O arm of the LORD. Wake up as in days past, as in generations of old. Was it not You who cut Rahab to pieces, who pierced through the dragon? 10 Was it not You who dried up the sea, the waters of the great deep, who made a road in the depths of the sea for the redeemed to cross over? 11 So the redeemed of the LORD will return and enter Zion with singing, crowned with everlasting joy. Gladness and joy will overtake them, and sorrow and sighing will flee.

9 Awake, awake, clothe yourself with strength, O arm of the LORD! Awake as in the days of old, the generations of ages past! Was it not you who hacked Rahab to pieces, who pierced the dragon? 10 Was it not you who dried up the sea, the waters of the great deep, who made the depths of the sea a road for the redeemed to cross over? 11 And the ransomed of the LORD will return and come to Zion with singing, with everlasting joy upon their heads. Gladness and joy will overtake them; sorrow and sighing will flee away.

Notes

The voice shifts abruptly: now it is the people (or the prophet on their behalf) crying out for God to act. The doubled imperative עוּרִי עוּרִי ("Awake! Awake!") is bold, even daring -- as if God has been sleeping while his people suffer. The same verb will be turned back on Jerusalem in verse 17 ("Rouse yourself! Rouse yourself!"), creating a powerful symmetry: the people call on God's arm to awake, and God calls on his people to awake.

The "arm of the LORD" (זְרוֹעַ יְהוָה) is one of the great theological images of the Old Testament, representing God's active power in history, especially in the Exodus (Exodus 6:6, Deuteronomy 4:34, Psalm 77:15). The people invoke it here by recalling its past deeds. לִבְשִׁי עֹז ("clothe yourself with strength") personifies the arm as a warrior donning armor for battle -- a metaphor that will recur in Isaiah 52:10 ("The LORD has bared his holy arm") and Isaiah 59:16-17 (where God dons righteousness as a breastplate).

Verse 9b introduces the figure of רַהַב and תַּנִּין ("the dragon" or "the sea monster"). These names operate on two levels simultaneously. In the mythic imagination of the ancient Near East, Rahab and the dragon/sea-serpent represent the primeval chaos waters that God subdued at creation -- a motif shared (in transformed form) with Babylonian and Ugaritic literature. But in Israelite usage, "Rahab" is also a name for Egypt (Psalm 87:4, Isaiah 30:7), and the drying up of the sea (v. 10) is unmistakably the Exodus. The verb הַמַּחְצֶבֶת ("who hacked/cut to pieces") and מְחוֹלֶלֶת ("who pierced") are violent, visceral words. Isaiah deliberately fuses creation and Exodus into a single act of divine combat: the God who tamed chaos at the beginning is the same God who defeated Egypt at the sea, and he is being summoned to do it again.

Verse 10 makes the Exodus connection explicit: God dried up יָם ("the sea") and מֵי תְהוֹם רַבָּה ("the waters of the great deep"). The word תְהוֹם ("deep") echoes Genesis 1:2 ("the deep"), reinforcing the creation-Exodus fusion. God made a דֶּרֶךְ ("road") in the sea for גְּאוּלִים ("the redeemed") to cross -- a clear reference to the crossing of the Red Sea (Exodus 14:21-22).

Verse 11 is virtually identical to Isaiah 35:10, and its reappearance here is deliberate. The פְדוּיֵי יְהוָה ("the ransomed of the LORD") will return to Zion with רִנָּה ("singing") and שִׂמְחַת עוֹלָם ("everlasting joy"). The language is processional -- a great pilgrimage of liberated exiles streaming back to Jerusalem. The closing line -- נָסוּ יָגוֹן וַאֲנָחָה ("sorrow and sighing will flee away") -- personifies grief as an enemy that is routed. The new Exodus will be even more glorious than the first.

Interpretations

The Rahab/dragon imagery and its relationship to creation and the Exodus have been understood in several ways:

The LORD's Comfort: Do Not Fear Mortals (vv. 12--16)

12 "I, even I, am He who comforts you. Why should you be afraid of mortal man, of a son of man who withers like grass? 13 But you have forgotten the LORD, your Maker, who stretched out the heavens and laid the foundations of the earth. You live in terror all day long because of the fury of the oppressor who is bent on destruction. But where is the fury of the oppressor? 14 The captive will soon be freed; he will not die in the dungeon, and his bread will not be lacking. 15 For I am the LORD your God who stirs up the sea so that its waves roar -- the LORD of Hosts is His name. 16 I have put My words in your mouth, and covered you with the shadow of My hand, to establish the heavens, to found the earth, and to say to Zion, 'You are My people.'"

12 "I, I am the one who comforts you. Who are you that you fear a mortal who will die, a son of man who is given up like grass? 13 You have forgotten the LORD your Maker, who stretched out the heavens and founded the earth. You tremble continually, all day long, before the fury of the oppressor, as he aims to destroy. But where is the fury of the oppressor? 14 The one bowed down will quickly be set free; he will not die in the pit, and his bread will not fail. 15 For I am the LORD your God, who stirs up the sea so that its waves roar -- the LORD of Hosts is his name. 16 I have placed my words in your mouth and sheltered you in the shadow of my hand -- to plant the heavens and lay the foundation of the earth, and to say to Zion, 'You are my people.'"

Notes

God now responds to the people's cry of verses 9--11 with emphatic self-identification: אָנֹכִי אָנֹכִי הוּא מְנַחֶמְכֶם ("I, I am the one who comforts you"). The doubled אָנֹכִי is intensely emphatic -- it is God himself, and no other, who will bring comfort. The rhetorical question that follows shames their fear: why should they dread אֱנוֹשׁ יָמוּת ("a mortal who will die") or בֶּן אָדָם חָצִיר יִנָּתֵן ("a son of man who is given up like grass")? The word אֱנוֹשׁ (a term for humanity emphasizing frailty and mortality) contrasts sharply with the eternal God of verse 6. Compare Psalm 103:15-16: "As for man, his days are like grass."

Verse 13 diagnoses the root cause of their fear: they have וַתִּשְׁכַּח ("forgotten") the LORD their Maker -- the same God who נוֹטֶה שָׁמַיִם ("stretched out the heavens") and וְיֹסֵד אָרֶץ ("founded the earth"). The contrast is devastating: they tremble before a human מֵצִיק ("oppressor"), while forgetting the God who made the universe. The verse ends with a dismissive question: וְאַיֵּה חֲמַת הַמֵּצִיק ("But where is the fury of the oppressor?") -- implying that the oppressor and his rage are already vanishing.

Verse 14 promises that צֹעֶה ("the one bowed down" or "the captive who crouches") will speedily be released. He will not die לַשַּׁחַת ("in the pit" or "in the dungeon") and his bread will not fail. This is a direct promise of liberation from Babylonian captivity.

Verse 15 reidentifies the speaker with a formula of divine power: "I am the LORD your God, who stirs up the sea" (רֹגַע הַיָּם). The verb רגע can mean either "to stir up" or "to still" -- both meanings underscore God's sovereign control over the most powerful natural force the ancient world knew. The title יְהוָה צְבָאוֹת ("the LORD of Hosts") caps the identification.

God has placed his words in the mouth of his people (or his prophet) and sheltered them בְּצֵל יָדִי ("in the shadow of my hand") -- the same hand that created the world. The purpose clauses that follow are astonishing: לִנְטֹעַ שָׁמַיִם וְלִיסֹד אָרֶץ ("to plant the heavens and to lay the foundation of the earth"). The verb נטע ("to plant") is unexpected -- one plants a garden, not the sky. This language suggests that God's redemptive work is nothing less than a new creation, and that Zion's restoration is of cosmic significance. The verse climaxes with the covenantal declaration: עַמִּי אָתָּה ("You are my people") -- the fundamental covenant formula (Hosea 2:23, Jeremiah 31:33).

Awake, O Jerusalem: The Cup of Wrath Removed (vv. 17--20)

17 Awake, awake! Rise up, O Jerusalem, you who have drunk from the hand of the LORD the cup of His fury; you who have drained the goblet to the dregs -- the cup that makes men stagger. 18 Among all the sons she bore, there is no one to guide her; among all the sons she brought up, there is no one to take her hand. 19 These pairs have befallen you: devastation and destruction, famine and sword. Who will grieve for you? Who can comfort you? 20 Your sons have fainted; they lie at the head of every street, like an antelope in a net. They are full of the wrath of the LORD, the rebuke of your God.

17 Rouse yourself! Rouse yourself! Stand up, O Jerusalem, you who have drunk from the hand of the LORD the cup of his wrath; the bowl of the cup of staggering you have drunk, you have drained to the dregs. 18 There is no one to lead her among all the sons she has borne; there is no one to take her by the hand among all the sons she has raised. 19 These two things have befallen you -- who will grieve for you? -- devastation and destruction, famine and sword -- who can comfort you? 20 Your sons have collapsed; they lie at the head of every street like an antelope in a net, filled with the wrath of the LORD, the rebuke of your God.

Notes

The second great "Awake!" of the chapter now addresses not God's arm but Jerusalem herself: הִתְעוֹרְרִי הִתְעוֹרְרִי ("Rouse yourself! Rouse yourself!"). The verb is the same root (עור, "to awake") used in verse 9, creating a deliberate echo. In verse 9 the people called on God to wake up; now God calls on his people to wake up. The structure suggests that God has already answered the people's prayer, and now Jerusalem must respond.

Jerusalem is personified as a woman who has drunk כּוֹס חֲמָתוֹ ("the cup of his wrath") and קֻבַּעַת כּוֹס הַתַּרְעֵלָה ("the bowl of the cup of staggering"). The "cup of wrath" is a recurring prophetic image for divine judgment that must be consumed in full (Jeremiah 25:15-28, Psalm 75:8, Habakkuk 2:16). The word תַּרְעֵלָה ("staggering" or "reeling") conveys the image of a person so drunk they cannot stand -- a picture of Jerusalem utterly overwhelmed by judgment. The verb מָצִית ("you have drained to the dregs") means she has consumed every last drop; the punishment has been endured completely.

Verse 18 deepens the pathos: among all the בָּנִים ("sons") Jerusalem bore and raised, there is none to מְנַהֵל ("lead" or "guide") her and none to מַחֲזִיק בְּיָדָהּ ("take her by the hand"). The mother-city is bereft; her children are too devastated to help her.

Verse 19 lists four calamities in two pairs: הַשֹּׁד וְהַשֶּׁבֶר ("devastation and destruction") and הָרָעָב וְהַחֶרֶב ("famine and sword"). The doubled question -- "who will grieve for you?" and "who can comfort you?" -- emphasizes Jerusalem's utter desolation. A textual note: the Masoretic Text reads מִי אֲנַחֲמֵךְ ("how can I comfort you?"), with God as the speaker struggling to find comfort for the afflicted city. The Dead Sea Scrolls, LXX, Syriac, and Vulgate read "who can comfort you?" -- a third-person question. Most English translations follow the latter reading.

Verse 20 presents a devastating image: Jerusalem's sons lie collapsed בְּרֹאשׁ כָּל חוּצוֹת ("at the head of every street") like כְּתוֹא מִכְמָר ("like an antelope in a net") -- a wild, noble animal trapped and helpless. They are הַמְלֵאִים חֲמַת יְהוָה ("filled with the wrath of the LORD"). The image is both heartrending and sobering: this suffering is not random misfortune but the consequence of covenant unfaithfulness.

The Cup Transferred to the Tormentors (vv. 21--23)

21 Therefore now hear this, you afflicted one, drunken, but not with wine. 22 Thus says your Lord, the LORD, even your God, who defends His people: "See, I have removed from your hand the cup of staggering. From that goblet, the cup of My fury, you will never drink again. 23 I will place it in the hands of your tormentors, who told you: 'Lie down, so we can walk over you,' so that you made your back like the ground, like a street to be traversed."

21 Therefore hear this, you afflicted one, who are drunk but not with wine. 22 Thus says your Lord, the LORD, your God who contends for his people: "See, I have taken from your hand the cup of staggering; the bowl of the cup of my wrath -- you will not drink from it again. 23 And I will put it into the hand of your tormentors, who said to you, 'Bow down so that we may walk over you,' and you made your back like the ground, like a street for them to walk on."

Notes

Verse 21 addresses Jerusalem as עֲנִיָּה ("afflicted one") and וּשְׁכֻרַת וְלֹא מִיָּיִן ("drunk, but not with wine"). The drunkenness is not from alcohol but from the staggering effects of divine judgment -- the cup of wrath from verse 17. This phrase echoes Isaiah 29:9, where Jerusalem is described as blind and drunk, but not from wine.

Verse 22 introduces the divine speaker with a remarkable accumulation of titles: אֲדֹנַיִךְ יְהוָה וֵאלֹהַיִךְ ("your Lord, the LORD, and your God"). The additional designation יָרִיב עַמּוֹ ("who contends/pleads for his people") is legal language -- the same God who once brought a lawsuit against his people (cf. Isaiah 1:2-4) now takes up their case as their advocate. The great announcement follows: הִנֵּה לָקַחְתִּי מִיָּדֵךְ אֶת כּוֹס הַתַּרְעֵלָה ("See, I have taken from your hand the cup of staggering"). The perfect tense לָקַחְתִּי ("I have taken") is again prophetic -- the action is as good as done. The promise is absolute: לֹא תוֹסִיפִי לִשְׁתּוֹתָהּ עוֹד ("you will not continue to drink from it again").

Verse 23 reveals where the cup goes: into the hand of מוֹגַיִךְ ("your tormentors"), those who humiliated Jerusalem by commanding, שְׁחִי וְנַעֲבֹרָה ("Bow down so we may walk over you"). The final image is haunting: Jerusalem וַתָּשִׂימִי כָאָרֶץ גֵּוֵךְ ("made your back like the ground") -- literally prostrating herself as a human road for conquerors to trample. This practice of victors literally walking on the backs of the conquered is attested in ancient Near Eastern reliefs and texts (Joshua 10:24). The reversal of this humiliation is the climax of the chapter: the cup of wrath now passes to the oppressor, and Jerusalem's degradation is ended.

This passage flows directly into Isaiah 52:1-2, where the command "Awake, awake, put on your strength, O Zion!" completes the pattern: the arm of the LORD has been called to awake (51:9), Jerusalem has been called to awake from judgment (51:17), and now Zion is called to awake in triumphant beauty (52:1).

Interpretations

The image of the "cup of wrath" being transferred from Jerusalem to her enemies has significant theological implications:
