Psalm 98 — When the Rivers Join the Song

Why are rivers, mountains and people invited to celebrate the coming of a just King?

Overview

From Israel's remembered deliverance to the whole creation's hope of a just world

Key text — Psalm 98:3, 9 (study rendering): The farthest reaches of the earth have witnessed the saving work of our God. Let creation rejoice before the LORD, for he comes to govern the earth with righteousness and its peoples with equity.

Imagine a song beginning in a small community that has survived a great disaster. At first, those who sing are remembering what God has done for them. Then the doors open. The music spills into the streets, crosses borders, and reaches people who were not there when the rescue occurred. Finally even the river, the sea, and the mountains are invited to join.

That is the extraordinary movement of Psalm 98. It begins with the LORD's saving work for Israel and ends with the hope of his just rule for the whole earth. Between those two horizons, worship becomes more than private gratitude. It becomes the announcement that the God who has kept faith with his people has purposes as wide as creation itself.

And the psalm leaves us with a question: If God's coming justice makes the rivers sing, what kind of world—and what kind of people—are we being invited to become?

1.0 Introduction

Psalm 98 is one of the most exuberant songs in the Psalter. There is no direct complaint, no petition for rescue, and no anxious debate with an adversary. Instead, a command rings out: Sing a new song! The reason is not that the worshipers have discovered a fresh musical style. God has acted in a way that calls for renewed testimony.

The psalm moves through three widening circles:

- Verses 1–3 — Remembered salvation: Israel is summoned to sing because the LORD has acted with power, righteousness, covenant love, and faithfulness. - Verses 4–6 — The nations' celebration: The whole earth is invited to greet the LORD as King with voice and instruments. - Verses 7–9 — Creation's chorus: Seas, rivers, mountains, and the inhabited world rejoice because the LORD comes to judge the earth rightly.

These are not three disconnected pictures. What God has done for Israel discloses what kind of King he is for the nations; what his kingship promises the nations gives the rest of creation reason to celebrate. The final judgment is therefore not introduced as an embarrassment hidden behind the music. It is the reason the music can reach the ends of the earth.

Central message: The God who remembers his covenant and makes salvation visible before the nations is also the righteous King of the whole creation. His coming judgment is good news because it promises a world governed by justice, faithfulness, and equity.

2.0 Historical and Literary Context

Psalm 98 belongs to Book Four of the Psalter (Psalms 90–106), where repeated declarations of divine kingship answer the questions left by the apparent collapse of David's dynasty in Psalm 89. Human thrones may fail. The LORD's kingship remains the source of Israel's hope (Pss. 90; 93; 96–99).

The Hebrew heading simply identifies this composition as “A psalm.” It names no author, ruler, battle, or date. The ancient Greek Psalter adds a Davidic attribution, but this does not establish that David composed the Hebrew psalm. Its language resembles Isaiah 40–55, especially the declaration that the LORD exposes his holy arm before the nations and that the ends of the earth see his salvation (Isa. 52:10). It may have spoken powerfully to a community remembering release from Babylonian domination, yet neither that setting nor a particular festival can be demonstrated beyond doubt. The psalm is capable of gathering many acts of divine deliverance into one public confession (Goldingay 2008, Psalm 98, “Interpretation”).

Literarily, Psalm 98 is closely related to Psalm 96. Both begin by commanding a new song, both summon the nations and the created order, and both conclude with the LORD's coming to judge the world rightly. Nevertheless, the emphasis is different. Psalm 96 extensively calls the nations to recognize God's supremacy. Psalm 98 begins by recounting an accomplished act of salvation for Israel and asks what that act means for everyone else. Goldingay draws attention to the change of audience: the first section speaks of our God, while the second addresses all the earth (Goldingay 2008, Psalm 98).

Psalm 97 also prepares us to understand the song. There, the King's appearing comes amid fire and lightning, exposing false gods and summoning his people to reject evil. Now Psalm 98 insists that the same holy and righteous King makes the world glad. Holiness is not the opposite of joy; rightly understood, it is what makes the future of joy trustworthy.

Derek Kidner calls Psalm 98 “King and Saviour” and notes its traditional Latin opening, Cantate Domino. He describes its distinctive atmosphere as unbroken praise. Yet that gladness is grounded, not vague: it concerns God's victory, public righteousness, and the restoration of a rightly ordered world (Kidner 2014, 384–86).

One important structural detail deserves notice. The Hebrew verbs of verses 1–3 predominantly describe what the LORD has done. The last verse then points to the LORD's coming or manifesting his rule. Worship stands between memory and expectation: it recalls grace already witnessed and anticipates justice still awaiting its full realization.

3.0 Walking Through the Text

3.1 Psalm 98:1 — A new song for an act of salvation

The opening command is unmistakable: Sing to the LORD a new song, because he has done wonderful things. In the Bible, a new song often celebrates a fresh disclosure of God's saving power (Pss. 96:1; 144:9; Isa. 42:10). Its newness does not require novelty for its own sake. An ancient confession receives a new voice because the LORD's faithfulness has been encountered anew.

The reason for the song is that God's right hand and holy arm have brought salvation. These are poetic expressions for divine power exercised in action. The psalm is not teaching that God has a literal human body. It speaks in embodied imagery familiar from the exodus and from Isaiah's announcements of restoration (Exod. 15:6, 12; Isa. 51:9–11; 52:10). God's arm is described as holy: the power being celebrated belongs to the One whose character is unlike that of oppressive rulers.

The Hebrew word often rendered salvation can carry the sense of victory, rescue, or deliverance. Kidner observes that the breadth of the word matters: divine victory is not merely the defeat of an enemy; it has a saving purpose for those in danger. A rescue that simply exchanges one tyranny for another would not express the fullness of this biblical hope (Kidner 2014, 385).

Some translations express the verse as God's own arm achieving victory for him. The point is that no competing deity has secured this deliverance and no human power is to be treated as the ultimate savior. The song gives the decisive credit to the LORD.

3.2 Psalm 98:2–3 — What Israel has received, the nations are invited to see

Verse 2 moves from God's action to its public disclosure. The LORD has made his salvation known and revealed his righteousness before the eyes of the nations. Righteousness here is not merely a private moral quality and need not be reduced to vindication of one party. It is the King's faithful, right-making action—his willingness to uphold what is right and to act for those bound to him.

Verse 3 gives that claim a particular history: God has remembered his steadfast love and faithfulness toward the house of Israel. The Hebrew vocabulary recalls covenant commitment: ḥesed, often rendered loyal love or steadfast kindness, and ʾĕmûnâ, faithfulness or reliability. To say that God “remembered” does not imply that he had previously forgotten. In biblical idiom remembrance means that a promise is brought into active effect (compare Exod. 2:24; 6:5).

This specificity is essential. The poet does not speak vaguely about a deity who saves people everywhere by bypassing history. He speaks of the God of Israel, whose concrete relationship with a particular people becomes visible to the nations. Goldingay insists that Israel's place in the story must not disappear when Christians read the poem universally (Goldingay 2008, “Theological Implications”).

Then the song widens: all the ends of the earth have seen the salvation of our God (v. 3, thematic rendering). The text does not require that every individual has literally stood at the scene of a specific historical rescue. This is celebratory, prophetic language for the world-embracing significance of God's action. Isaiah 52:10 provides a particularly close parallel.

We should resist turning this into Israel's self-congratulation. The psalm does not say the nations must admire Israel because Israel is better than they are. It says the nations are invited to recognize the LORD's faithfulness. The people who have been rescued become witnesses, not proprietors, of salvation.

3.3 Psalm 98:4–6 — A royal welcome heard across the earth

The subject changes. Verses 1–3 have spoken from the perspective of a worshiping community recalling what our God has done. Now verse 4 addresses all the earth and calls it to shout joyfully. The language piles up verbs: break forth, rejoice, and sing. This is not simply a command to feel happy. It is an invitation to recognize the King openly.

The psalm then names the lyre, the sound of singing, trumpets, and the horn. Music is both personal and communal, crafted and spontaneous. The straight metal trumpets and the animal-horn instrument had distinct uses in Israel's life, including announcements and ceremonial occasions (Num. 10:1–10; 1 Kgs. 1:39). Their presence here turns the song into a royal welcome (Goldingay 2008, Psalm 98:4–6).

The verse ends: make a joyful sound before the King, the LORD (v. 6, study rendering). Unlike rulers who need constant flattery, this King is praised because his power secures justice. Worship tells the truth about the throne.

This noisy invitation does not mean that quieter forms of worship are invalid. Psalm 95 includes kneeling before the LORD; Psalm 131 celebrates a soul made quiet. The Psalter accommodates more than one faithful bodily response. Psalm 98's particular purpose is to show that news this good should not be confined to the private circle that first received it.

Here an ethical question emerges: Can our congregations sing about the God of all nations while treating people of other languages, ethnicities, classes, or backgrounds as outsiders? The widening audience of the psalm asks worshipers to bring their social habits into line with their song.

3.4 Psalm 98:7–8 — The sea roars, the rivers clap, the mountains sing

The invitation now passes beyond the human world. Let the sea roar, together with everything filling it. Let the rivers clap their hands and the mountains sing for joy together.

The images are gloriously excessive. We are not expected to imagine rivers with literal fingers or mountains possessing human vocal cords. Poetry gives human gestures to nonhuman creation so that we might hear the world differently. A river rushing over stones, a wave breaking on the shore, wind moving through mountain forests—these become signs that God's world is not silent before its Maker (compare Pss. 19:1–4; 96:11–13; Isa. 55:12).

There is also a striking transformation from Psalm 93. There, the surging waters evoke terrifying forces, yet the LORD is mightier than their roar (Ps. 93:3–4). Here the sound of the sea belongs to an orchestra of celebration. What appears overwhelming to human beings is not beyond God's authority; creation can be envisioned joining the welcome offered to its Creator.

The personification carries a theological truth without turning poetry into a simplistic scientific claim. The natural world has a place in God's purposes that is larger than its usefulness to people. The psalm does not say rivers and mountains are divine or should be worshiped. Creation is not the object of praise but a fellow witness to the Creator.

And its invitation comes with a troubling question for us. If the rivers are pictured applauding the arrival of the righteous Judge, what does it say about us when we pollute them, displace vulnerable communities for profit, or treat the living world as endlessly expendable? Psalm 98 is not a modern environmental policy document, but it gives worshipers a reason to regard the nonhuman world with gratitude, care, and restraint (Gen. 2:15; Rom. 8:19–23).

3.5 Psalm 98:9 — Why judgment is the reason for rejoicing

Only at the conclusion does the psalm say directly why this vast chorus is celebrating: the LORD comes to judge the earth. He will judge the world with righteousness and the peoples with equity.

For many modern readers the word judgment sounds solely like condemnation. Scripture certainly takes evil and accountability seriously. Yet the Old Testament also associates judgment with the restoration of justice for those who have been denied it. The judge does not merely pronounce penalties; a good judge discerns the truth, prevents the strong from consuming the weak, and puts disordered relationships right (Pss. 9:7–9; 72:1–4; 96:13; 99:4).

The last word of Psalm 98 is often translated equity or uprightness. The nations are not being invited to rejoice over an unpredictable ruler favoring one ethnic group. They are being offered the promise of a King who does what is right. No bribe, military advantage, propaganda campaign, or inherited privilege can corrupt his judgment.

There is a nuance in the timing. Some interpreters hear the Hebrew expression as “he has come” to judge; many English versions render it “he is coming.” Goldingay notes the connection between the salvation God has already performed and the authority he now exercises or will display among the peoples. We need not choose between a God absent until the future and a world already fully healed. Psalm 98 declares that his reign has been disclosed in history and that its righteous implications extend beyond what has yet been seen (Goldingay 2008, Psalm 98:9).

Judgment is good news for the oppressed, but the psalm does not authorize religious people to celebrate the humiliation of anyone they dislike. Its moral standard challenges the singer as well as the stranger. To welcome God's righteous government is also to consent to having our own conduct brought into its light.

4.0 Theological Reflection

4.1 Salvation is remembered, not invented by the worshiper

The new song begins with what God has done, not with what the community wishes it could claim for itself. Christian worship can easily become dominated by atmosphere, performance, or the reputation of its leaders. Psalm 98 places the decisive act outside our control. We sing because God has shown mercy and remained faithful (vv. 1–3; compare Ps. 77:11–15).

The past is not a prison in which believers remain nostalgically trapped. Remembering God's acts becomes fuel for hope: the faithfulness that sustained his people yesterday allows them to face tomorrow without pretending all their questions are answered.

4.2 Covenant faithfulness opens outward rather than closing in

God remembers his love for Israel, and therefore the ends of the earth can see his saving work. Particularity and universality are not rivals here. God's relationship with a people is the beginning of a worldwide witness. Genesis 12:1–3 already joins God's blessing of Abraham with the blessing of the families of the earth; Isaiah 49:6 pictures Israel's calling in relation to the nations.

The church must not use this universal vision to erase Jewish identity or to claim that God's relationship with Israel was merely a disposable first chapter. Christians come to know Israel's God through Israel's Scriptures, history, and Messiah (John 4:22; Rom. 9:4–5; 11:17–24). A worldwide song should make us more grateful for the story from which it came, not less.

4.3 Worship is rehearsal for a world made right

The trumpets announce the arrival of the King before the final transformation of all things is visible. Kidner observes that worship now anticipates God's fuller appearing (Kidner 2014, 385–86). We sing ahead of the dawn, not because injustice is imaginary, but because it is not worthy of the final word.

A church singing about God's righteous rule should practice that rule in small, tangible ways: truthfulness in financial decisions, protection of children and vulnerable adults, fair treatment of workers, careful listening to those who have been silenced, and refusal to sanctify political violence. Our praise becomes credible when our communal life begins to resemble the kingdom it celebrates.

4.4 Judgment is hope for those denied justice—and a summons to repentance

A world without judgment would leave victims with no promise that wrongdoing will ever be named or addressed. Psalm 98 offers the opposite: God will rule with equity. That promise should encourage those suffering exploitation, corruption, war, or discrimination. It should also unsettle those who benefit from injustice (Isa. 11:1–5; Amos 5:21–24).

Yet believers must not confuse the certainty of divine justice with certainty about all of God's decisions in individual cases. We can speak clearly against documented harm while refusing to pretend we know the eternal destiny of our opponents. The Judge of all the earth acts rightly; his people are responsible for mercy, integrity, truthful witness, and appropriate accountability (Gen. 18:25; Rom. 12:17–21).

4.5 The future of the human family includes the renewal of creation

Psalm 98's ending is larger than the rescue of individual souls. Seas, rivers, mountains, human societies, and the exercise of justice belong together. Human wrongdoing wounds human neighbors and often the environments on which they depend. The biblical hope is therefore not simply escape from material creation, but the liberation and renewal of God's world (Isa. 55:12–13; Rom. 8:19–23; Rev. 21:1–5).

The psalm does not offer a detailed blueprint for ecological restoration, but its vision gives us a posture. We care for land and water not because nature replaces God, but because the Creator loves what he has made and promises it a future.

5.0 Canonical and Christological Horizon

The Bible's larger narrative begins with creation pronounced good (Gen. 1), then tells of human rebellion and its spread into violence and fractured relationships (Gen. 3–11). God's calling of Abraham introduces a promise meant to reach all families of the earth (Gen. 12:1–3). Psalm 98 inhabits that trajectory: Israel's salvation is visible to the nations and creation joins their praise.

The exodus supplies an early model of a new song after deliverance (Exod. 15:1–18). Isaiah's vision of renewed Zion again connects God's saving arm with the ends of the earth seeing his salvation (Isa. 52:7–10). When Christians read Psalm 98 through the New Testament, these are not discarded preliminaries. They are the story in which Jesus appears.

The birth narratives announce joy for Israel and for the wider world (Luke 2:10–14, 29–32). Jesus proclaims God's kingdom, brings restoration to people excluded from ordinary social life, and teaches that justice and mercy belong at the heart of the law (Mark 1:14–15; Luke 4:16–21; Matt. 23:23). His death and resurrection become, for the apostles, God's decisive victory over sin and death—a salvation with implications far beyond one community (1 Cor. 15:20–28; Eph. 2:11–22).

A Christian reading can therefore hear a deeper fulfillment of Psalm 98's announcement. Jesus is the Messiah of Israel and the risen Lord to whom the nations are invited. But this Christological horizon must not erase what Psalm 98 first confesses: God's faithful deeds within Israel's own history. Nor should the psalm be treated as though it literally named Jesus before the fact. The relationship is canonical and theological, not a claim that every line was originally an explicit messianic prediction.

The New Testament also preserves the psalm's future dimension. Romans 8:19–23 portrays creation groaning for liberation, waiting for the renewal bound up with God's children. Revelation 15:3–4 joins divine victory to praise from the nations; Revelation 21–22 looks toward a renewed heaven and earth where God's presence brings healing and where injustice and death no longer rule.

The hymn “Joy to the World,” associated with Isaac Watts, is famously inspired by Psalm 98. Its language of the earth receiving her King fits the psalm's horizon. Although often sung at Christmas, its images also point toward the fuller reign of God and a healed creation. This familiar hymn can help Christians hear what the psalm itself dares to imagine: not only people singing about salvation, but the whole world welcoming the righteous King.

6.0 Life Application

Tell the story behind your praise. Rather than relying only on general religious enthusiasm, identify a particular experience of God's faithfulness or an act of grace you have witnessed. Share it humbly, without implying that everyone else must have the same experience.
Let the music widen your circle. Make room in worship and fellowship for people of different languages, generations, economic situations, and national backgrounds. If the earth is invited to praise the King, no local culture should pretend to own him.
Celebrate justice, not domination. When praying for leaders and institutions, ask that power be used with truth, fairness, and protection of the vulnerable. Resist the temptation to mistake the loudest or most successful ruler for the most righteous one.
Practice the kingdom before you can see its completion. Tell the truth in business, refuse bribery, pay people fairly, listen to the injured, and seek peaceful ways to address wrongdoing. Small acts of integrity are consistent with the Judge we praise.
Receive creation as a fellow witness. Take time to notice a river, tree, field, mountain, or shoreline. Let its beauty enlarge gratitude and lead to a practical act of care—reducing waste, protecting water, or participating in local stewardship.
Leave room for lament alongside the new song. Psalm 98 does not cancel Psalm 88. Some worshipers are still grieving or waiting for rescue. Invite them into the community without demanding that they express joy on command. Our singing should hold hope for them, not silence them.

7.0 Reflection Questions

Why does Psalm 98 begin with what God has already done rather than with what Israel hopes will happen next?
How can God's particular faithfulness to Israel become good news for the nations without erasing Israel's place in the story?
What does it mean for a congregation to praise the LORD as King while submitting its own exercise of authority to his standard of justice?
How does the image of rivers clapping their hands change the way we think about creation and our responsibilities toward it?
Why is the LORD's coming judgment a cause for celebration rather than only fear? Who most needs to hear that promise?
How do Jesus' resurrection and the New Testament hope of a renewed creation extend the psalm's meaning while respecting its original voice?
What would it look like to sing a “new song” in a community that is still carrying grief, injustice, or disappointment?

8.0 Response Prayer

LORD, our King and our Savior, we praise you for the wonders of your faithfulness. You have remembered your promises; you have not abandoned the work of your hands.

When we forget your mercy, teach us to remember. When our worship becomes a performance, return us to the joy of speaking the truth about you. When we guard your gifts as if they belong to us alone, open our doors and widen our hearts.

Let our songs be heard in our conduct. Make our judgments fair, our words honest, our leadership humble, and our hands ready to help. Stand beside those awaiting justice, and teach us not to speak lightly of their pain.

Let the rivers and mountains remind us that your care reaches beyond our small concerns. Train us to honor the world you have made and to long for its healing.

Through Jesus Christ, Israel's Messiah and the world's Lord, give us courage to hope for the day when righteousness is visible in all the earth and every creature can rejoice before you.

Amen.

9.0 Window into What Comes Next

Psalm 98 finishes in celebration. The whole earth has been called to welcome the LORD as King, and even the sea, rivers, and mountains join the chorus. The reason is striking: the Judge is coming to rule the peoples with righteousness and equity.

Psalm 99 takes up the same royal theme but changes the atmosphere. The nations tremble. The LORD reigns enthroned above the cherubim. Zion is summoned to exalt him, and the repeated refrain announces his holiness. The psalm remembers Moses, Aaron, and Samuel as people who called on God and were answered, even as it speaks of divine forgiveness and accountability.

The two songs belong together. Psalm 98 teaches us to rejoice that God's judgment is just; Psalm 99 teaches us to approach that just King with reverence, obedience, and awe. Joy without holiness can become shallow. Holiness without the memory of mercy can become crushing. Book Four invites us to hold them together.
