Publicad, y haced llegar, y entren todos en consulta: ¿ quién hizo oir esto desde el principio, y lo tiene dicho desde entonces, sino yo Jehová? Y no hay más Dios que yo; Dios justo y Salvador: ningún otro fuera de mí.
Anunciai, e achegai-vos; e consultai juntamente em conselho; quem fez ouvir isto desde a antiguidade? Quem desde então tem anunciado? Por acaso não sou eu, o SENHOR? E não há ouro Deus além de mim, Deus justo e Salvador; ninguém, a não ser eu mesmo .
Déclarez-le, et faites-les venir!
Verkündiget und machet euch herzu, ratschlaget miteinander. Wer hat dies lassen sagen von alters her und vorlängst verkündigt? Habe ich's nicht getan, der HERR? und ist sonst kein Gott außer mir, ein gerechter Gott und Heiland; und keiner ist außer mir.
Verkondigt en treedt hier toe, ja, beraadslaagt samen: wie heeft dat laten horen van ouds her? Wie heeft dat van toen af verkondigd? Ben Ik het niet, de HEERE? en er is geen God meer behalve Mij, een rechtvaardig God, en een Heiland, niemand is er dan Ik.
Annunziatelo, fateli appressare, prendano pure consiglio assieme! Chi ha annunziato queste cose fin dai tempi antichi e l’ha predette da lungo tempo? Non sono forse io, l’Eterno? E non v’è altro Dio fuori di me, un Dio giusto, e non v’è Salvatore fuori di me.

Give the word, put forward your cause, let us have a discussion together: who has given news of this in the past? who made it clear in early times? did not I, the Lord? and there is no God but me; a true God and a saviour; there is no other.

Scholars' Consensus
Commentators agree that in this verse God summons the nations to a courtroom contest. The central claim: only Yahweh has foretold events like Cyrus's rise and Babylon's fall long before they happened (Barnes, Calvin). That predictive power proves he alone is God. On the phrase “a just God and a Saviour,” there is no disagreement that both attributes belong to Yahweh and describe his character in action. Barnes explains that God’s justice is shown in keeping his promises, and his saving work is the fulfillment of those promises, not a contradiction but a single, faithful activity. Jamieson-Fausset-Brown echoes this: God is righteous in keeping his word, therefore a Savior to his people. Gill sees in this a direct witness to Christ, who satisfies divine justice while saving sinners. The consensus is firm: the text presents God’s justice and salvation as two sides of his covenantal faithfulness, not as competing qualities.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- No tension view: Barnes and JFB argue that God’s justice is his faithfulness to his promises; saving his people is an act of justice, not mercy overriding justice.
- Atonement resolution: Gill and many Christian interpreters see the cross as the place where God’s justice against sin was fully satisfied, enabling him to be both just and Savior (Rom 3:25–26).
- Salvation through judgment view: Keil and Delitzsch see justice and salvation as integrated in God’s sovereign acts: he judges the nations and saves a remnant, displaying both attributes in the same historical events.
What is clear: God alone is God, he is both righteous and a deliverer, and there is no other being like him—this is not in dispute across traditions.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| God’s justice and salvation | Both are attributes of God; he is righteous in character and actively saves his people. | Some traditions (e.g., Barnes, JFB) see no inherent tension, God’s justice is expressed in keeping covenant promises to save. Others (e.g., Gill) resolve the tension by pointing to Christ’s atonement, where justice and mercy meet. |
| Meaning of ‘just’ (tsaddiq) | It refers to God’s faithfulness to his word and his upright character. | Whether it primarily connotes punitive or retributive justice (punishing sin) or covenantal faithfulness (doing what is right by his people). |
| Identity of the Savior | It is Yahweh himself who saves. | Christian readers identify this as a reference to Christ (God the Son), while Jewish interpretation sees only the God of Israel acting directly. |
| Scope of fulfilled prophecy | Fulfilled prophecy proves Yahweh’s sole deity, he alone can foretell distant events. | Whether the primary referent is Cyrus’s conquest (historical) or the final eschatological salvation (Keil, JFB see both layers). |
Historical & Cultural Context
Isaiah 45 stands within a series of trial speeches (chs. 41, 46) where God calls the nations and their idols to present evidence of divinity. The immediate historical backdrop is the Babylonian exile and the rise of Cyrus the Persian, who would conquer Babylon and decree the return of the Jews. God’s argument rests on fulfilled prophecy: he alone announced Cyrus by name and described his victories long before they occurred (Isaiah 44:28, 45:1). The verse opens with a challenge to “declare and present it”, likely “your strong arguments” (Cambridge Bible, Barnes). The idols and their worshippers are told to take counsel together, but they can produce no such predictions. The cultural context is a world steeped in idolatry, where carved wooden images were carried in processions and prayed to for help (Isaiah 45:20). God singles out “a just God and a Saviour,” using terms that evoke his covenant relationship with Israel: tsaddiq (righteous) describes his fidelity to his promises, and moshi‘a (deliverer) recalls his pattern of rescuing his people from Egypt onward. This courtroom scene looks ahead to the ends of the earth being invited to look to God and be saved (v.22), making the verse a hinge between judgment on idols and universal salvation.
Textual Notes
The consulted sources note no significant textual variants affecting meaning. Clarke mentions that the Septuagint reads yedau (“let them know”) for the Masoretic yivva‘atsu (“let them take counsel”), but this does not change the verse’s force. The Cambridge Bible observes that the object of “bring near” may have dropped out of the text, suggesting “your strong arguments” from Isaiah 41:21. The overall sense remains stable across manuscripts.
Reception History
The Early Church read this verse as a prophecy of Christ, the righteous Savior who fulfills God’s justice on the cross. Augustine cited it to argue that God alone saves, and that his justice and mercy are not opposed. The Reformers (Calvin, Luther) stressed the argument from prophecy as a foundation for faith against idolatry. In the Wesleyan tradition, Adam Clarke used it to emphasize God’s free offer of salvation to all. Modern evangelical preaching often pairs it with Romans 3:26 to show how God can be just and the justifier of believers. Across traditions, verse 21 has been a key text for the uniqueness of God and the gospel invitation.
Preaching This Verse
Three-point outline
- God’s Unique Claim, He alone foretells the future; idols cannot. This establishes his exclusive deity and trustworthiness.
- God’s Just Character, He is righteous in all his ways, faithful to his promises, and never contradicts his own nature when he saves.
- God’s Saving Work, His justice and salvation are not at odds; together they display his covenant love and power to deliver.
Five-point outline
- The Courtroom Invitation, God summons the nations to present evidence (v.21a).
- The Witness of Prophecy, The fulfilled word proves God’s sole divinity (v.21b).
- The Exclusive Claim, “There is no other God besides me” (v.21c).
- The Double Attribute, “A just God and a Saviour”, justice and mercy meet in one person (v.21d).
- The Final Appeal, This is not a bare declaration; it invites trust (see v.22).
Illustration hooks
- A courtroom with two witnesses: One witness’s story matches every known fact; the other contradicts basic evidence. Which do you trust? God presents prophecy as his unbroken testimony.
- An honest judge who also pays the fine: A judge finds you guilty but steps down from the bench to cover your penalty himself. That is the picture of a God who is just and also a Savior.
- A lost child in a foreign city: The only person who can identify the child correctly is the parent. God says: only I know where history is heading, because I am the one directing it.
Questions your congregation is asking
- How can God punish sin and still forgive sinners without being unfair?
- When I suffer, how do I know God is still in control and keeping his promises?
- What makes Christianity different from other religions? Isn’t every god the same at the core?
Leading a Discussion
This verse draws a direct line between God’s ability to predict the future and his identity as the only true God. It also raises the question: how can the same God be perfectly just and also the one who saves? As a group, read Isaiah 45:20, 25 to see the full context. Then consider how this passage helps us trust God when life seems uncertain and when we struggle to reconcile his justice with his mercy.
Discussion questions
- Why does God challenge the nations “to take counsel together” and present their case? What does this reveal about his character?
- What specific event is God referring to when he says “who has shown this from ancient time” (Barnes, Cambridge Bible)?
- What does the word “just” (tsaddiq) tell us about how God acts toward his people? Does it primarily describe punishment or covenant faithfulness?
- How can God be both “just” and “Saviour” without one cancelling the other? Share how different Christian traditions have answered this question.
- How does fulfilled prophecy strengthen your personal trust in God’s promises for the future?
- Verse 22 follows with “Look to me, and be saved, all the ends of the earth.” How does this broaden the scope of salvation beyond Israel?
- In what areas of your life do you need to remember that God is both just and a Savior, not one at the expense of the other?

What the Commentators Say
11 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke notes a textual variant in the original Hebrew. While the standard reading speaks of taking counsel, an ancient manuscript reads "let them come together by appointment," and Clarke suggests this may be the authentic wording. The Septuagint also offers a different rendering, "let them know."
Barnes' Notes on the Bible Protestant 1832
Barnes argues that God being "a just God and a Saviour" is not a contradiction but a single attribute: God is just and true in saving His people. He notes the passage does not specifically refer to the atonement, yet the language perfectly describes how the cross shows God maintaining law's honor while extending mercy, something no human government can achieve.
Calvin's Commentaries Reformed 1564
Calvin stresses that the prophet dares unbelievers to bring their best arguments and take counsel together, only to show that their conspiracy amounts to nothing. God’s word alone provides sufficient support for his people’s faith. Calvin ties this to both the promised redemption and Babylon’s overthrow, demonstrating God’s foreknowledge and
Cambridge Bible for Schools and Colleges Anglican 1880
The Cambridge Bible Schools commentary draws attention to the scene's timing after the great crisis, addressing the survivors of a worldwide judgment. The challenge to the nations is the same as earlier: who foretold these events? The prediction of Cyrus's victories demonstrates both God's righteousness and His exclusive role as Deliverer.
Geneva Bible Notes Reformed 1599
Tell ye and bring them, and let them take counsell together, who hath declared this from the beginning? or hath tolde it of olde? Haue not I the Lord? and there is none other God beside me, a iust God, and a Sauiour: there is none beside me.
Gill's Exposition of the Bible Baptist 1748
Gill contrasts the utter inability of false gods or their priests to predict anything in advance with the Lord's proven record of prophecy, especially through Christ. He points out that Christ foretold his own betrayal, death, and resurrection exactly as they happened, proving he alone is the just God and the only Saviour.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB contrasts God's ability
Keil & Delitzsch OT Commentary Protestant 1876
Keil-Delitzsch sees the "escaped of the heathen" as a remnant spared through judgment, not yet converted but open to salvation. The prophet's telescopic vision merges Cyrus's victories into a final eschatological scene where surviving nations, convinced by Jehovah's fulfilled predictions, gather to acknowledge Him as the only God.
Lange's Commentary Reformed 1857
Lange notes that Scripture gives Cyrus the title “anointed,” normally reserved for Israel’s coming Redeemer, while Israel is only called “servant of the Lord.” This distinction shows that Cyrus is a type of Christ, who alone fulfills both roles as lowly servant and anointed king.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Matthew Henry highlights the absurdity of idolatry: people set up a piece of wood, overlay it with gold, and pray to a god that cannot save. He notes the wood remains the real substance beneath the decoration. The call to the escaped nations is to abandon this folly and turn to the true God.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley reads the call to "take counsel" as a challenge to idolaters to confer together and try to defend their own false gods. The word "this" points to a single great work: Babylon's destruction and the redemption of God's people, which only the Lord could declare and accomplish.
