Cuando, haciendo terriblezas cuales nunca esperábamos, descendiste, fluyeron los montes delante de ti.
Como quando fazias coisas temíveis, as quais nunca esperávamos; quando tu descias, e os montes se tremiam diante de tua presença.
Jamais on n’ a appris ni entendu dire,
durch die Wunder, die du tust, deren man sich nicht versieht, daß du herabführest und die Berge vor dir zerflössen!
Toen Gij vreselijke dingen deedt, die wij niet verwachtten; Gij kwaamt neder, van Uw aangezicht vervloten de bergen.
Quando facesti delle cose tremende che noi non aspettavamo, tu discendesti, e i monti furono scossi dinanzi a te.
Jako gdyś czynił dziwy, którycheśmy się nie spodziewali; zstąpiłeś, a od oblicza twego góry się rozpływały.
Когда Ты совершал страшные дела, нами неожиданные, и нисходил, - горы таяли от лица Твоего.
你曾行 我們不能 逆料 可畏的事。那時你降臨，山嶺 在你面前 震動。
While you do acts of power for which we are not looking, and which have not come to the ears of men in the past.
Verse in Context
Scholars' Consensus
Commentators across traditions agree that this verse recalls the Exodus and Sinai theophanies. Barnes notes the “terrible things” refer to God’s acts in Egypt and the wilderness, especially the descent on Sinai. Cambridge Bible calls “terrible things” a standing phrase for the marvels of the Exodus. Gill adds that the people “looked not for” these works because they were unprecedented and far beyond expectation. The point is not that Israel failed to look for God, but that his saving power surpassed anything they could have imagined. This memory fuels the prayer that God would again rend the heavens and come down.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Sinai theophany (primary): Most commentators (Barnes, Gill, JFB) identify the 'coming down' with Sinai and the 'awesome things' with the Exodus deliverance, supported by Judges 5:4–5 and Psalm 68:8.
- General saving acts: Wesley and others apply the phrase more broadly to all of God’s unexpected works in Israel’s history, including the wilderness and conquest.
What is clear: God performed extraordinary, unprecedented acts to save and reveal himself to Israel, and those acts are the foundation for the community’s prayer for renewed intervention.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Historical reference of 'awesome things' | Commentators agree the language echoes God’s mighty acts in the Exodus and at Sinai (Barnes, Gill, Cambridge). | Some (e.g., Wesley) apply it more broadly to all of God’s deliverances, while others (Cambridge) insist the Sinai theophany is primary. |
| Meaning of 'we didn’t look for' | All sources agree the phrase means the acts were beyond human expectation, not that the people neglected to seek God. | Minor difference: Barnes emphasises the unprecedented nature; Gill adds that the people had no right to expect such displays. |
| Textual integrity of verse 3b | Standard English translations treat the whole verse as original. | Cambridge Bible suggests the second half may be a copyist’s error repeating v.1; others (e.g., Keil & Delitzsch, JFB) treat it as an intentional repetition for emphasis. |
Historical & Cultural Context
The prayer in Isaiah 64 comes from a community in distress, likely Judah during the Babylonian exile or shortly after, with the temple in ruins (Isaiah 64:10, 11). The people cry for God to tear open the heavens and intervene as he did in the founding events of their nation. The language of mountains quaking or melting before God’s presence echoes the Sinai theophany (Exodus 19:18; Judges 5:4, 5; Psalms 68:8; 97:5). In the ancient Near East, mountains symbolised stability and power. When they tremble or flow, it signals that nothing can withstand the Lord’s arrival. The phrase “when you did awesome things which we didn’t look for” points back to those early deliverances (Deuteronomy 10:21; 2 Samuel 7:23). The Exodus was a pattern of divine rescue that exceeded every human plan. By recalling it, the community expresses both its desperate need and its trust that the same God who acted then can act again.
Textual Notes
The verse as it appears in the Hebrew text is stable across major manuscripts. However, the Cambridge Bible for Schools and Colleges suggests that the second half (“you came down, and the mountains quaked at your presence”) may be a copyist’s error, since it repeats verbatim from verse 1. The editors argue the passage gains compactness by its excision. Other commentators (JFB, Keil & Delitzsch) do not adopt this view, seeing the repetition as a deliberate echoing for rhetorical effect. The consulted sources note no other significant textual variants.
Reception History
Isaiah 64:3 has been read across Christian history as a plea for God to act in ways that surpass human planning. Early church writers, like Clement of Rome, used the surrounding passage (v.4) to speak of God’s blessings for those who wait. The verse has been sung in hymns that yearn for revival, especially those describing God’s descent in power. During times of persecution and exile, this text gave language to the hope that God’s past deliverances were a pattern for future rescue. In the modern era, it has been quoted in prayers for spiritual awakening and in sermons calling believers to trust in God’s unexpected movements.
Preaching This Verse
Three-point outline
- The God who acts beyond expectation. Israel’s history shows God doing what no one anticipated, deliverances and judgments that left even the mountains trembling (Exodus 34:10).
- The prayer that echoes the past. The people do not invent new theology; they root their cry in proven acts of salvation, asking God to do again what he has done.
- The hope that waits. The “unlooked for” nature of God’s work reminds us that he is not bound by our limited expectations or our despair.
Five-point outline
- God’s awesome works are acts of power that shake creation.
- Those works catch us off guard: no one expected Sinai to burn or the sea to part.
- Such works are the basis for prayer in times of ruin.
- Memory of the old deliverance fuels confidence in a new one.
- God’s presence, when he comes, is both terrible and saving.
Illustration hooks
- A family facing foreclosure prays for a miracle, and a relative they had not heard from in years offers exactly the amount needed, an unexpected provision that shifts their perspective on God’s timing.
- In a medical crisis, a patient receives a treatment that was not available even a few years earlier. What was “unlooked for” becomes a reason for gratitude and faith.
- A church going through a split prays for unity; a reconciling conversation happens with someone no one expected to initiate it, recalling that God’s ways outpace our strategies.
Questions your congregation is asking
- Does God still do “awesome things” today, or were those only in Bible times?
- How can we pray for God to “come down” when our situation seems hopeless?
- What do we do when we feel we have been waiting so long that we no longer expect God to act?
Leading a Discussion
This verse sits inside a passionate prayer for God to intervene as he did at the Exodus. The community remembers that God’s past actions were both powerful and surprising. As you discuss, reflect on how memory shapes faith and hope.
Discussion questions
- Read Isaiah 64:1-3 together. What picture do these verses paint of God?
- The people say God did “awesome things which we didn’t look for.” What does that phrase reveal about their understanding of God’s character?
- Which specific events do the commentaries connect to “awesome things” and “mountains quaking”? How does that background inform how you read the verse?
- Why do you think the community remembers the past in order to plead for the present?
- When have you experienced a situation where God acted in a way you did not expect?
- How does this passage challenge or encourage the way you pray in difficult seasons?
- In what ways does this verse point forward to Christ’s coming or the hope of resurrection?

What the Commentators Say
7 public-domain commentaries, condensed into plain language.
Barnes' Notes on the Bible Protestant 1832
Barnes emphasizes that the "terrible things" God did for Israel were completely unprecedented and beyond anything they had reason to expect. The deliverance from Egypt, the descent on Sinai, and the shaking of the mountains were acts of power that had never been witnessed before.
Cambridge Bible for Schools and Colleges Anglican 1880
The Cambridge commentary notes a probable copyist's error: the second half of this verse repeats the previous verse in the original Hebrew. Deleting it makes the passage more compact, and the phrase "terrible things" echoes the Exodus wonders, anticipating the final deliverance.
Geneva Bible Notes Reformed 1599
When thou diddest terrible things, which we looked not for, thou camest downe, and the mountaines melted at thy presence.
Gill's Exposition of the Bible Baptist 1748
Gill notes that the "terrible things" God did were unexpected and unlooked-for, pointing to the plagues in Egypt, the Red Sea crossing, and especially Mount Sinai. He also observes that the mountains flowing down included not only Sinai but Seir and Paran, as Jewish tradition holds.
Keil & Delitzsch OT Commentary Protestant 1876
Keil-Delitzsch argue that the phrase "God beside Thee" with a negation throughout Isaiah 40-66 always affirms that Jehovah alone is God. Here the meaning is that no other deity has ever been heard or seen who acts for those who wait for Him. Paul's quotation in 1 Corinthians 2:9 aligns with this, referencing the same waiting.
Lange's Commentary Reformed 1857
Lange interprets the prayer as a desperate plea for God to intervene in a visibly overwhelming way—rending the heavens and dissolving mountains—to prove His reality to a hardened, exiled people. He contrasts this hoped-for display of power with God’s previous disciplinary anger, which only deepened their sin and uncleanness. The plea rests on God alone being the living God who acts for those who wait on Him.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley understands the "terrible things" as unrecorded acts God performed among the Egyptians and later in the wilderness. He interprets "looked not for" as events no one could have anticipated. The "mountains" are a metaphor for kings, princes, and other rulers.
