Porque ¿ qué Dios hay fuera de Jehová? ¿ y qué fuerte fuera de nuestro Dios?
Porque quem é Deus, a não ser o SENHOR? E quem é rocha, a não ser o nosso Deus?
Les voies de Dieu sont parfaites,
Denn wo ist ein Gott außer dem HERRN, oder ein Hort außer unserm Gott?
Gods weg is volmaakt; de rede des HEEREN is doorlouterd; Hij is een Schild allen, die op Hem betrouwen.
Poiché chi è Dio fuor dell’Eterno? E chi è Ròcca fuor del nostro Dio,
Droga Boża doskonała jest; słowo Pańskie jest ogniem wypławione. Tarczą jest wszystkich, którzy w nim ufają.
除了 耶和華，誰是 神呢？除了我們的 神，誰 是磐石呢？
For who is God but the Lord? or who is a Rock but our God?
Verse in Context
Scholars' Consensus
Commentators across traditions agree that this verse is a sweeping declaration of Yahweh's exclusive deity and his role as the only secure refuge. Adam Clarke notes that 'none is worthy of adoration but the self-existent, eternal, infinitely perfect, and all-merciful Being.' Barnes adds that 'no other being has evinced the power, the wisdom, and the goodness which properly belong to the true God.' The Cambridge Bible points out that the singular Eloah (God) is used here instead of the usual plural Elohim, drawing attention to God's unique, personal nature. Gill expands the confession to include the Son and Spirit, affirming that all three are one God. Wesley summarizes: 'Our Lord is the only God, and therefore there is none that can hinder him from accomplishing his own work.' The verse is not abstract doctrine; it is David's testimony after God delivered him from every enemy, as Calvin observes. The confession that Yahweh alone is God and Rock grounds the entire psalm in personal, lived trust.
How settled is the interpretation?
Interpretive difficulty: Low
What is clear: The verse unequivocally asserts that Yahweh alone is God and that he alone is the unshakable rock of refuge for his people.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Use of singular 'Eloah' vs. plural 'Elohim' | The singular form is poetic and emphasizes God's unique, personal nature. | Some see it as a stylistic choice for heightened poetry; others suggest it may deliberately distinguish the true God from false gods. |
| Identity of the 'rock' | The rock refers to Yahweh as the only source of security and salvation. | Gill and others see this as inclusive of the Son and Spirit, while most Reformed tradition reads it as a direct reference to the Father, with the rock typologically pointing to Christ. |
| Function of the rhetorical question | The question forces a response of exclusive devotion and trust. | Some emphasize its doxological purpose (praise), while others stress its polemical function against idolatry. |
| Connection to the New Testament | The verse affirms the God of Israel is the only true God. | Traditional Christian readings apply the title 'rock' to Christ in light of 1 Corinthians 10:4; Jewish readings maintain the verse speaks only of Yahweh, without Trinitarian implication. |
Historical & Cultural Context
Psalm 18 is a royal thanksgiving, placed on David's lips near the end of his life, celebrating deliverance from all enemies, including Saul. The same poem appears in 2 Samuel 22 with slight variations, embedding it in the historical narrative of David's reign. The rhetorical question 'Who is God, except Yahweh?' echoes the Song of Moses (Deuteronomy 32:31,39), which itself confronts Israel with the uniqueness of their God against the false gods of the nations. Hannah's prayer (1 Samuel 2:2) also uses 'rock' as a divine title, rooting the image in Israel's earliest confessions.
The term 'rock' (tzur in Hebrew, though the text is not supplied) was a familiar metaphor in a land of rocky hills and fortresses. A rock meant shade, water, and defense. To call God a rock was to declare him utterly reliable and protective in a world of shifting loyalties. The singular Eloah for God (rather than the common plural Elohim) appears mostly in Job and the poetry of Deuteronomy and Isaiah, giving the verse a solemn, almost creedal tone. David's audience would have heard this not as a new idea but as the climax of generations of covenant faith. In a culture surrounded by the gods of Egypt, Philistia, and Canaan, this question demanded an answer: Is there any other being who has shown such power and goodness? The implied answer, none, is meant to evoke worship and renewed trust.
Textual Notes
The supplied sources note no significant textual variants for Psalm 18:31. The parallel passage in 2 Samuel 22:32 reads almost identically, confirming the verse was a fixed element of David's song. Some minor differences exist (e.g., the Septuagint may have slight shifts in wording), but the meaning is stable across manuscripts. The NET Bible notes that the Hebrew of this verse is clear and uncomplicated.
Reception History
Psalm 18:31 has been a cornerstone of Jewish and Christian confession. Early Christian writers cited it against polytheism, affirming that only the God of Israel is worthy of worship. The image of God as Rock entered the church's hymnody and liturgy (e.g., ancient hymns and creedal statements). During the Reformation, Calvin and Luther used this verse to stress that salvation rests solely on God, not human effort. In the Wesleyan tradition, the verse underscored God's power to deliver completely. The rhetorical question format was often employed in catechesis to teach the first commandment. Today, it remains a favorite for private meditation and public praise, reminding believers that no person or power can replace the true God.
Preaching This Verse
Three-point outline
- The exclusivity of Yahweh as God. The rhetorical question assumes no other being can be compared. This is not a philosophical argument but a confession born from rescue. David has seen God act; he knows there is no other.
- The security of Yahweh as Rock. A rock is unchanging, a reliable shelter. The verse invites hearers to move from knowing God is God to trusting God as their rock, personal, present, provable.
- The personal confession ‘our God.’ The shift from ‘Yahweh’ to ‘our God’ makes the truth communal. David speaks for the people of God, inviting them to share in the certainty that this God alone deserves faith and praise.
Five-point outline
- The question: Who is God? The verse forces a choice. It refuses to leave the matter abstract.
- The answer: Yahweh alone. The covenant name of God is the only one that fits.
- The metaphor: Rock. This word calls to mind strength, permanence, and refuge.
- The scope: ‘Our God.’ The confession is personal and corporate, not just a truth but a treasure.
- The result: Trust and praise. The whole psalm flows from this conviction into thanksgiving and confidence.
Illustration hooks
- House foundation: You only get one foundation for a house. If it shifts, everything cracks. The verse asks: what foundation are you building your life on?
- Emergency call: In a crisis, people call one number. That one number is supposed to work every time. David says God is that emergency number, no backup needed.
- Loyalty test: In a world with many claims on your trust (money, relationships, institutions), this verse functions like a litmus test: who or what has proven unshakable?
Questions your congregation is asking
- How can I be sure God is the only true God when other religions seem sincere?
- What does it mean practically to treat God as my ‘rock’ in daily decisions?
- If God is my rock, why do I still feel insecure in hard times?
Leading a Discussion
Opening framing: This verse is a rhetorical question that forces a verdict. It was spoken by David after years of danger and deliverance, so it is not a theory but a testimony. As a group, let the question hang in the air before answering it from your own lives.
Discussion questions
- Observation: What two things does the verse ask? Why are they phrased as questions rather than statements?
- Interpretation: Why is the word ‘rock’ used instead of a more abstract word for God? What associations does a rock carry in the Bible?
- Cross-reference: Read 1 Samuel 2:2 and Deuteronomy 32:31. How does Psalm 18:31 echo these earlier texts? What does that tell us about how Israel confessed God?
- Context: Look at the verses around Psalm 18:31 (especially vv. 32-35). How does the confession in v. 31 connect to David’s description of God’s help in battle?
- Application: In what areas of life do you most need to trust God as your rock today? What would change if you truly believed there is no rock besides him?
- Theological theme: How does this verse relate to the first commandment? How does it speak to the exclusivity of salvation in the Old Testament?
- Prayer: Write a one-sentence prayer based on this verse, something you can take into the week.

What the Commentators Say
8 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke notes that the Hebrew name Eloah and the title Jehovah distinguish the one true God from all else. Only this self-existent, eternal, infinitely perfect and merciful Being deserves worship. He also draws on the image of a rock, interpreting it as a fountain that continually supplies grace and goodness.
Barnes' Notes on the Bible Protestant 1832
Barnes argues that the true nature of God—His power, wisdom, and goodness—is found in no other being. Applying the image of a rock, he adds that no one else offers the safety and defense we find in our God.
Calvin's Commentaries Reformed 1564
Calvin stresses that David wrote this psalm not to celebrate his own victories but to magnify God as the true source of them. He also sees David's reign as a deliberate image and type of Christ's kingdom, assuring believers that Christ will triumph over every enemy through the Father's power.
Geneva Bible Notes Reformed 1599
The Geneva Notes stress that this rhetorical question leaves no room for doubt: there is no other true God besides the Lord, and no other power that matches His. The point is to affirm God's exclusive deity and unmatched strength, cutting off any thought of rival gods or human ability.
Gill's Exposition of the Bible Baptist 1748
Gill stresses that Jehovah alone is God by nature, unlike the false gods of the nations or human magistrates. He clarifies that this includes the Father, Son, and Spirit as one God. The rock metaphor points to Jehovah as the only true refuge, contrasting with false rocks like the Delphian rock of Apollo.
Keil & Delitzsch OT Commentary Protestant 1876
Keil and Delitzsch stress that the "perfect way" in this passage means a path made absolutely smooth and straight by God, free from stumbling and leading directly to a divine goal. They clarify the image of the hind: it pictures swiftness in attack and pursuit, not in flight, fitting a warrior king. The brass bow likewise underscores the heroism of one who bends it with his hand.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry notes that David does not boast in his own warrior skill but traces every victory back to God's enabling. The point is that the believer's strength comes entirely from the Lord, who trains, equips, and protects those who trust Him.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley highlights that Christ's exclusive identity as the only God means no power exists that can stop Him from finishing what He has begun. This underscores the absolute certainty of His work. No creature or force can stand in the way.
