Tornaré en soledad montes y collados, haré secar toda su hierba; los ríos tornaré en islas, y secaré los estanques.
Aos montes e morros tornarei em deserto, e toda sua erva farei secar; e tornarei aos rios em ilhas, e as lagoas secarei.

Scholars' Consensus
Commentators agree that this verse depicts God's absolute power to remove any hindrance to His deliverance. Barnes describes the imagery as 'the utter desolation which God would bring upon his foes,' suggesting the mountains and hills represent the cultivated, fortified strongholds of enemies. Calvin reads it similarly: 'all the defenses and military forces on which the wicked plume themselves shall not prevent God from setting his people at liberty.' Gill applies the language to 'kingdoms, greater and lesser', the Roman Empire and its rulers that opposed Christ. The Hebrew verbs are Hiphil (causative) forms of acharav ('to lay waste') and yavesh ('to dry up'), stressing that God actively and decisively causes this transformation. Most commentators avoid a literal reading of cosmology; instead they see the verse as God's promise that no power, whether political, spiritual, or geographical, can withstand His purpose.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Metaphorical (obstacles as enemies/idolatry): Context: v. 17 condemns idolatry; v. 13 presents God as warrior; most supplied commentators (Barnes, Calvin, Gill, Matthew Henry) interpret this way.
- Literal cosmic upheaval: Parallels with Psalms 18:7, 107:33, and Isaiah 11:15 suggest actual transformation of nature; some readers take the language at face value.
What is clear: God sovereignly and decisively removes every barrier to accomplish His deliverance, whether those barriers are political, spiritual, or physical.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Literal vs. Metaphorical Destruction | Christians agree that God demonstrates absolute power to remove barriers to His saving purpose. | Some (e.g., a literalist reading of creation/eschatology) see actual cosmic upheaval; others (most supplied commentators) interpret mountains, rivers, and pools as symbols of proud nations, idolatries, and false securities. |
| The Identity of the Enemies | God's judgment targets what opposes His people and His glory. | Gill and Jamieson-Fausset-Brown specify pagan Rome and idolatrous systems; Calvin and Barnes speak more broadly of any 'military forces' or 'cultivated portions' of enemy lands. |
| Timing of the Fulfillment | The verse points to a decisive intervention by God. | Matthew Henry sees initial fulfillment in the spread of the gospel and the fall of paganism; others (Keil & Delitzsch) link it to Israel's return from exile as a type of final redemption. |
Historical & Cultural Context
Isaiah 42 sits within the first 'Servant Song' (42:1, 9) and a broader oracle of judgment and hope. Immediately preceding verses (42:13, 14) picture Yahweh as a warrior whose long silence ends with a battle cry. The mountains and hills were not empty wilderness. In ancient Palestine, hillsides were commonly terraced for vineyards and olive groves (Barnes notes this). To 'lay waste mountains and hills' was to destroy a region's entire agricultural infrastructure, a familiar image of total war.
The rivers and pools held special significance. Rivers were life-giving arteries; drying them up meant cutting off a nation's sustenance. But water sources also had religious meaning: Canaanite and other pagan cults often worshipped at springs, streams, and pools (Gill links them to 'remains of idolatry'). To dry up the pools was to strike at the heart of idolatrous worship. The word אִי ('i) in 'islands' primarily means 'dry land' (Barnes, Cambridge Bible), so the image is of riverbeds becoming exposed, water replaced by barren ground.
Rare palindromic structure is noted by Keil and Delitzsch: the verse ends with the same verb ('I will dry up') that begins the second half, giving a sense of completeness and finality. The whole passage (vv. 14, 16) contrasts God's fierce judgment on enemies with His gentle leading of the blind. The destruction serves the deliverance: God flattens the obstacles to make a straight, lit path for His people.
Textual Notes
The supplied sources note one significant variant. Adam Clarke cites Houbigant's conjecture that אִיִּים ('islands') should instead read צִיִּים ('dry deserts' or 'waste places'), which would change the phrase to 'I will make the rivers deserts', reinforcing the desolation theme. However, the Masoretic Text reading is supported by the majority of manuscripts and versions. No other variants are mentioned in the consulted commentaries.
Reception History
Early Christian interpreters, such as those reflected in the Geneva Bible notes, read Isaiah 42:15 as a prophecy of Christ's victory over the spiritual strongholds of the Gentile world. The mountains and hills were understood as the pride of human kingdoms and demonic powers. During the Reformation, Calvin emphasized that the verse assures believers that no earthly power can withstand God's will to save. Matthew Henry applied the imagery to the apostolic age, when the gospel 'pulled down Satan's strongholds.' In modern scholarship, the verse is often read in its original Near Eastern context: a vivid portrayal of Yahweh as a divine warrior who levels all obstacles to lead His people home. Across all eras, the verse has been sung in hymns of deliverance, particularly those celebrating God as a refuge in times of persecution.
Preaching This Verse
Three-point outline
- God’s power to destroy everything that opposes Him, mountains and hills represent the proud and powerful; God brings them low.
- God’s power to drain every false source of life, rivers and pools symbolize the resources and idolatries that people trust; He dries them up.
- God’s power to make a way where none exists, destruction of obstacles is not an end in itself; it clears the path for His people (v. 16).
Five-point outline
- The God who was silent is now a warrior (vv. 13, 14).
- He strips the proud of their strength (mountains and hills).
- He cuts off the sustenance of rebellion (herbage, pools).
- He reverses the natural order to save (rivers become dry land).
- He does all this to lead the blind home (v. 16).
Illustration hooks
- Road construction: A new highway doesn't stop at a hill or river, engineers blast the rock, bridge the water. God does the same for His people, only faster and without equipment.
- A parent removing obstacles: When a child reaches for something dangerous, a parent doesn't hesitate to clear the way. God's 'destruction' is protective and purposeful.
Questions your congregation is asking
- What 'mountains' am I facing that seem too big for God to move?
- If God is destroying, how do I know I'm not the one being destroyed?
- How do I trust that God's fierce actions come from love?
Leading a Discussion
Isaiah 42:15 pictures a God who acts decisively to remove every barrier. But His destruction is never random; it always clears a path for redemption. As you discuss, notice how the harsh language of verse 15 is immediately followed by the tender promise to lead the blind (v. 16). This tension is at the heart of God's character.
Discussion questions
- Read verses 13, 15 together. What emotions does this picture of God stir in you? Why?
- What do mountains and rivers represent in the Bible (e.g., Psalm 121:1, Psalm 46:4)? How does that help you understand this verse?
- Barnes and Calvin both see this as God removing obstacles to deliver His people. Can you think of times when God seemed to 'destroy' something in your life that later proved to be a hindrance?
- Verse 14 says God was silent for a long time. Have you ever felt God was silent? How does the sudden eruption of action here encourage you?
- How does the contrast between judgment (v. 15) and guidance (v. 16) shape your understanding of God's character?
- What 'pools' (sources of security) do people in your community trust instead of God? What would it look like for God to 'dry them up'?
- How can this passage give you confidence to face a situation that seems impossible?

What the Commentators Say
11 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke proposes that the Hebrew word usually translated "islands" should instead be read as "dry deserts," a textual conjecture he attributes to Houbigant. This changes the image from habitable land to barren wilderness.
Barnes' Notes on the Bible Protestant 1832
Barnes reads the violent imagery as God's symbolic judgment against idolatry itself. The devastation of cultivated hills, dried-up streams and ruined pools is not literal destruction but a picture of God overturning everything that pagan worship has built—temples, altars and shrines. For Barnes the passage announces a permanent change as God finally goes forth as a conqueror to subdue the nations.
Calvin's Commentaries Reformed 1564
Calvin reads the mountains and hills not as allegorical symbols but as real obstacles, specifically the military might and defenses of the wicked. His point is straightforward: no human power, however invincible it appears, can stand against God when He decides to rescue His people. We need this reminder because visible strength often makes us doubt God's ability to deliver.
Cambridge Bible for Schools and Colleges Anglican 1880
The Cambridge commentary highlights the striking boldness of this passage’s anthropomorphism: God rousing himself from inaction and singing a battle song. Jehovah’s breath of anger dries up even the most fertile land, and the words “herbage” and “islands” carry specific meanings—dry land set against water.
Geneva Bible Notes Reformed 1599
I will make waste mountaines, and hilles, and drie vp all their herbes, and I will make the floods ylands, and I will drie vp the pooles.
Gill's Exposition of the Bible Baptist 1748
Gill identifies the mountains and hills as the kingdoms and rulers of Rome that opposed Christ, with the herbs as their common soldiers and supporters. He interprets the drying of rivers and pools as the complete removal of idolatry, though he also suggests it pictures God clearing away obstacles for His people, as at the Red Sea.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB reads the threat against mountains and islands as God's judgment on pagan religion itself. Mountains recall Palestine's terraced vineyards, but islands means dry lands. God will dry up the fountains of heathen oracles, doctrines, and idolatrous schools, cutting off the water that symbolizes their false teachings.
Keil & Delitzsch OT Commentary Protestant 1876
Keil and Delitzsch highlight how God's fiery breath acts as both judgment and deliverance at once. The same power that scorches mountains and dries up lakes turns a hostile land into a desert while clearing every obstacle for Israel's return, displaying God's righteousness in both wrath and love.
Lange's Commentary Reformed 1857
Lange highlights the paradox at the heart of this passage: the Servant of Jehovah is both meek and gentle, refraining from noise and violence, yet He is also the mighty warrior who cries out and defeats His enemies. This unity of opposites points to the mystery of the Servant's identity with Jehovah Himself.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Matthew Henry interprets these verses as a prophecy of God's powerful intervention through the gospel. After a long period of patient silence toward the Gentile world, God now goes forth as a warrior to attack and destroy Satan's kingdom, with Christ conquering through the preaching of the apostles.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley interprets the hills as proud and flourishing enemies, and the command to dry them up as God’s promise to remove every obstacle. The point is that God actively clears the path by cutting down whatever stands in the way.
