Scholars' Consensus
Commentators agree that this verse redirects attention from the human instrument to the divine source. The rhetorical question “Who caused his glorious arm to be at Moses’ right hand?” forces a single answer: God alone. Barnes notes that the deliverance from Egypt was so miraculous that “none but the true God could have performed it.” Gill is careful to point out that Moses’ rod is mentioned only “lest this should be attributed to Moses and his rod.” The “glorious arm” (literally “arm of his splendor,” from תִּפְאַרְתּוֹ) is a designation of God’s omnipotence displayed at the sea. All the supplied commentators identify the reference as the Red Sea crossing (Exodus 14, 15), not water from the rock. And they unite on God’s stated motive: “to make himself an everlasting name”, renown that spans every generation.
How settled is the interpretation?
Interpretive difficulty: Low
What is clear: God alone performed the miracle through Moses, and his motive was to secure an everlasting name.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Whether the “waters” refer only to the Red Sea or also to the Jordan | All consulted commentators identify the primary reference as the Red Sea crossing (Exodus 14). | Some readers (e.g., Poole in background material) extend the division to the Jordan (Joshua 3), but the supplied commentaries treat only the Red Sea. |
| The relationship between Moses’ hand and God’s arm | All commentators agree that God’s glorious arm was the true agent; Moses’ right hand was merely the instrument. | There is no significant debate; the rhetorical question is understood to emphasize divine sovereignty. |
| The meaning of “everlasting name” | All agree it refers to God’s reputation and renown established through the miracle, lasting through all generations. | Some emphasize God’s intent to demonstrate his power to surrounding nations (Barnes); others focus on the perpetual memory of the act (Gill). Both are compatible. |
| The subject of “remembered” in verse 11 | The verse begins a series of rhetorical questions looking back to the Exodus. | Keil and Delitzsch argue the people are the subject who remembers; Matthew Henry and older Jewish commentators see God as the one remembering. This affects whether verse 12 is a question from God or from the people. |
Historical & Cultural Context
Isaiah 63 is set in a community that has experienced exile and feels abandoned by God. The chapter begins with a sweeping review of God’s past kindnesses (vv. 7, 9), then confesses the people’s rebellion (v. 10). In verse 11 the people ask, “Where is he who brought them up out of the sea with the shepherd of his flock?” Verse 12 intensifies: “Who caused his glorious arm to be at Moses’ right hand?”
The Hebrew participle מוֹלִיךְ (“causing to go,” Hiphil of הָלַךְ) carries causative force: God actively guided his own power. The phrase “glorious arm” (זְרוֹעַ תִּפְאַרְתּוֹ) echoes Exodus 15:6, where Moses’ song celebrates “Your right hand, Yahweh, is glorious in power.” By setting “arm” and “right hand” close together, the text shows Moses’ hand as the visible point of contact, but God’s arm as the true agent. The underlying cultural assumption is that a deity establishes a “name”, reputation and honour, through acts of power no rival can match. Barnes observes that Egypt was the center of civilization, so a miracle there would reverberate across nations. God’s aim was a public demonstration that would never be forgotten. The deliverance through the Red Sea was Israel’s defining salvation event; in exile the people look back to it as the pattern for a new exodus.
Textual Notes

Reception History
This verse has been cherished in both Jewish and Christian traditions as a testament to God’s saving power. In Jewish liturgy, the Exodus recital (including the splitting of the sea) forms the core of the Passover Haggadah, constantly renewing the memory of God’s mighty act. Early Christian interpreters saw the “arm of the Lord” as a prefiguration of Christ, God’s power made manifest in redemption. The Reformation emphasis on the glory of God alone (soli Deo gloria) often appealed to this verse. Matthew Henry’s commentary treats it as part of the church’s grateful recognition of God’s past goodness, urging believers in every age to recount God’s works.
Preaching This Verse
Three-point outline
- God works through instruments without diluting his glory. The verse’s rhetorical question, “Who caused his glorious arm to be at Moses’ right hand?”, answers itself. Moses raised the rod, but the arm that drove the power belonged to God. This guards against two mistakes: thinking our efforts earn salvation, or thinking God cannot use us because of our weakness. He works in partnership, but the credit belongs to him.
- God’s ultimate motive is his own everlasting name. The verse ends with a purpose clause: “to make himself an everlasting name.” God’s self-glorification is not pride; it flows from his goodness. When he acts to make his name known, he spreads the knowledge of his character, mercy, power, faithfulness, so the world may trust him.
- Memory shapes prayer. The whole chapter is a prayer that begins with remembering. The exiled community looks back at the Red Sea and asks, “Where is that God now?” That question is not doubt; it is a plea for God to act again according to his name. Your own prayers can start the same way, review what God has done, then ask him to do it again.
Five-point outline
- God’s power is the source of every deliverance.
- Human leaders are honored but never the ultimate cause.
- The Red Sea crossing is a foundational act of salvation.
- God’s aim is a name that endures forever.
- This memory shapes the prayers of God’s people in exile.
Illustration hooks
- A ship captain at the helm while the crew follows instructions, the navigator’s skill gets the ship home, but the owner’s authority sent the ship.
- A coach who calls the plays while the quarterback executes; the win belongs to the team, but the coach’s strategy made it possible.
- A family remembering a grandparent’s sacrifice; the story becomes part of who they are.
Questions your congregation is asking
- “Does my work for God really matter when he gets all the glory?”
- “Why does God care so much about his name? Is that pride on God’s part?”
- “If God was with Moses, will he be with me today?”
Leading a Discussion
This verse invites us to look back at what God has done so we can trust him with what lies ahead. The community in Isaiah 63 remembered the Red Sea crossing and asked where that God had gone. Their memory was not idle nostalgia; it was a foundation for hope. As you discuss this passage, consider how remembering God’s past faithfulness shapes your present confidence.
Discussion questions
- Observation: What exactly does the verse say God did at Moses’ right hand?
- Observation: What was the purpose of the miracle, according to the verse?
- Interpretation: Why does the Bible ask “who” did it, rather than simply stating that fact?
- Interpretation: What does “glorious arm” tell us about the character of God?
- Application: How does remembering God’s past deliverances strengthen your faith during hard times?
- Application: In what areas of life do you need to remember that God is the one working through your efforts, not the other way around?
- Application: How can your small group keep God’s “everlasting name” central in your serving and praying together?

What the Commentators Say
8 public-domain commentaries, condensed into plain language.
Barnes' Notes on the Bible Protestant 1832
Barnes stresses that God performed the Red Sea miracle in Egypt, then the world's center of learning and power, so that the demonstration of His power would be undeniable to every nation. No false god or human strength could accomplish such a work, and God intended this act to build a reputation that would never be forgotten across all lands.
Cambridge Bible for Schools and Colleges Anglican 1880
This commentator argues that the "glorious arm" accompanying Moses refers to God's wonder-working power symbolized by the rod of God. The latter part of the verse points to the Red Sea crossing, not the water from the rock.
Geneva Bible Notes Reformed 1599
The Geneva note emphasizes that God led Israel through Moses as his instrument, but the power came from God's own glorious arm dividing the waters. The miracle was not primarily for Israel's rescue but to establish God's own everlasting renown.
Gill's Exposition of the Bible Baptist 1748
Gill stresses that while Moses lifted his rod over the sea, the real power came from God's glorious arm guiding Moses' hand. The miracle must not be credited to Moses or the rod; it was a display of divine omnipotence, done so that God would gain everlasting honor through the defeat of Pharaoh and his army.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB draws a sharp distinction between Moses' visible act and God's sovereign power. Moses' right hand was merely the instrument; God's own arm was the real force that parted the water. The miracle belongs entirely to God, not to Moses' gesture.
Keil & Delitzsch OT Commentary Protestant 1876
Keil-Delitzsch argues that the people themselves, not God, are the ones remembering the days of Moses, despite the Hebrew accents suggesting otherwise. The questions that follow, starting with "Where is He?", express human longing, not divine recollection. They reject the reading "the Moses of His people" as grammatically forced.
Lange's Commentary Reformed 1857
Lange notes that the prophet places himself in the position of the exiled church and grounds his prayer on a historical retrospect. By recalling God's former acts of salvation, especially through Moses and the angel of His presence, the prophet builds a foundation for pleading for deliverance in the present distress.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry observes that the prophet, speaking for the church, reviews God's past mercies and lovingkindnesses before turning to prayer for Israel's present distress. This backward look at God's faithful care becomes the foundation for asking his compassion anew.
