Shared ground
These closing lines finish a creation hymn with a final “wrap-up” of its main themes: Yahweh’s lasting honor, Yahweh’s active rule over the world, and a human voice that answers with praise. Explicitly, the poet asks that Yahweh’s glory endure (v.31), that Yahweh rejoice in what he has made (v.31), and then describes God’s power in nature with vivid images (v.32). The speaker then states a settled intention to sing for life (v.33) and to rejoice in Yahweh (v.34). The last verse adds a request that what damages God’s good world—“sinners…the wicked”—would be removed, and it ends with self-addressed praise and the acclamation “Praise Yah!” (v.35).
Where interpretation differs
1) “Let Yahweh rejoice in his works” (v.31): wish or confidence?
Some read this as a request the poet is making (“may God take pleasure in what he made”). Others hear it as near-certainty spoken as a prayer (“God does rejoice in his works”), so the line functions more like affirmation.
2) Earth trembling and mountains smoking (v.32): pure poetry or hint of specific events?
Many take these as poetic ways to say God’s power is effortless and overwhelming, not a report of an earthquake or volcano. Others think the imagery may echo real experiences of tremors or mountain fire/smoke, but used here to make a theological point.
3) “Let sinners be consumed…Let the wicked be no more” (v.35): what kind of removal?
Some read “consumed” mainly as the end of wicked influence—evil being cleared out so creation’s order can flourish. Others hear a stronger request for the end of the wicked themselves (including death or judgment). The text does not spell out a method (death, exile, disappearance), only the desired outcome: the corrupting presence is gone.
Why the disagreement exists
The key lines are written as prayers and poetic images rather than detailed descriptions. Hebrew-style prayer language can sound like a wish, a confidence statement, or both at once (especially in v.31). Likewise, v.32 uses picture-language that is intentionally not technical. In v.35, the verb “consumed” is forceful, but the verse gives no narrative details about how the removal happens.
What this passage clearly contributes
The ending of Psalm 104 ties creation theology to moral order. God is not only maker and sustainer; he is portrayed as the one before whom the world is unstable and responsive (v.32). Human praise is presented as an enduring vocation (“as long as I live,” v.33), and inner life (“meditation”) matters because it is offered as something meant to please God (v.34). Finally, the psalm links the goodness of creation with the removal of what ruins it (v.35), before closing with direct praise to and “Praise Yah!”
