Y ajustaré el juicio á cordel, y á nivel la justicia; y granizo barrerá la acogida de la mentira, y aguas arrollarán el escondrijo.
E porei o juízo como linha de medida, e a justiça como prumo; o granizo varrerá o refúgio da mentira, e as águas inundarão o esconderijo;
Je ferai de la droiture une règle,
Und ich will das Recht zur Richtschnur und die Gerechtigkeit zum Gericht machen; so wird der Hagel die falsche Zuflucht wegtreiben, und Wasser sollen den Schirm wegschwemmen,
En Ik zal het gericht stellen naar het richtsnoer, en de gerechtigheid naar het paslood; en de hagel zal de toevlucht der leugen wegvagen, en de wateren zullen de schuilplaats overlopen.
Io prenderò il diritto per livello, e la giustizia per piombino; la grandine spazzerà via il rifugio di menzogna, e le acque inonderanno il vostro ricetto.
A wykonam sąd według sznuru, a sprawiedliwość według wagi; i potłucze grad nadzieję omylną, a ucieczkę wody zatopią.
И поставлю суд мерилом и правду весами; и градом истребится убежище лжи, и воды потопят место укрывательства.
我必以 公平 為準繩，以公義 為線鉈。冰雹 必沖去 謊言的 避所；大水 必漫過 藏身之處。
And I will make right decision the measuring-line, and righteousness the weight: and the ice-storm will take away the safe place of false words, and the secret place will be covered by the flowing waters.

Scholars' Consensus
Commentators across traditions agree that this verse uses builder’s tools to picture God’s exact standard. The line (measuring cord) and plummet (leveling tool) were used by builders to ensure everything was straight and true. Here, God says he will make justice and righteousness function in the same way. Barnes emphasizes that this means judgment without any mercy mixed in, an exact rule, like a carpenter working by the line. Calvin focuses on the building side: God is reforming the church, making everything orderly after confusion. Gill and the Cambridge Bible see both aspects: the same standard that builds up the faithful also condemns the false. The hail and waters (cf. Exodus 9; Joshua 10) are images of divine judgment sweeping away the refuge of lies, the false security the scoffers boasted of in verse 15. All agree that God’s justice and righteousness are a single, indivisible standard: they establish the true building and demolish every counterfeit.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Exact judgment without mercy: Barnes emphasizes that God will measure by the line with no mercy intermingled, citing the hail and flood as pure judgment.
- Divine building and reformation: Calvin stresses that God is using justice and righteousness to build the church anew after confusion, like a master builder.
- Both building and judgment: Gill, Poole and the Cambridge Bible see the line and plummet as serving both purposes: building up the faithful and demolishing false refuges.
What is clear: God will use justice and righteousness as an exact, unyielding standard that exposes and sweeps away every false refuge, while establishing the building that rests on the cornerstone.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| The function of the line and plummet | They represent an exact standard, God will measure everything by justice and righteousness. | Barnes sees them as judgment without mercy; Calvin sees them as the reformation of the church; Gill and Poole hold that they serve both building and demolition. |
| The identity of the refuge of lies | It is the false security of the scornful rulers, their claim to have a covenant with death. | Some interpreters (e.g., Keil & Delitzsch) see it as the specific political alliance with Egypt; others (Gill) take it more broadly as any false trust, including temple confidence. |
| The relationship to the cornerstone (v. 16) | Verse 17 flows directly from verse 16: the same foundation brings both salvation and judgment. | Whether the line and plummet are part of the building process that establishes the church (Calvin) or are a separate act of judgment on those who reject the cornerstone (Barnes, Wesley). |
| The hail and waters as judgment | They symbolize divine judgment that sweeps away false refuges completely. | Some (Barnes, JFB) see them as the Assyrian invasion; others (Gill) connect them to the Roman destruction of Jerusalem or to final eschatological judgment. |
Historical & Cultural Context
Isaiah 28:17 stands in the middle of a prophecy against the rulers of Jerusalem in the late eighth century BC. These leaders, called scoffers in verse 14, trusted in political alliances, likely with Egypt, rather than in Yahweh. They boasted that they had made a covenant with death itself (v. 15), meaning they thought they had secured themselves against any disaster, even the Assyrian invasion that Isaiah had warned about. Their refuge of lies was the web of deception they told themselves: that their diplomacy, their walls, their temple would protect them.
The metaphor of the line and plummet comes directly from the building trade. A measuring line ensured straight walls; a plummet (a weight on a string) checked that a wall was truly vertical. Builders used them both for new construction and for demolition, marking which parts of a ruined building were to be pulled down (see 2 Kings 21:13). So when God says he will lay justice as the line and righteousness as the plummet, he signals that he is both the master builder and the demolisher. The hail and overflowing waters recall God’s judgments in Egypt (Exodus 9) and at Beth Horon (Joshua 10). They picture a storm that cannot be resisted, washing away anything not built on the true foundation.
The earlier verse 16 had announced a precious cornerstone laid in Zion, a promise of a sure foundation for those who believe. Verse 17 then shows the corollary: that same foundation becomes a standard of judgment for those who reject it. The rulers had hidden under falsehood; God’s truth would expose them.
Textual Notes
The consulted sources note no significant textual variants for Isaiah 28:17 itself. The word יָעָה (sweep away) occurs only here in the Qal stem, but its meaning is clear from context and cognate languages. The parallel word שָׁטַף (overflow) is common. The Masoretic text is stable; all major English translations reflect the same Hebrew reading.
Reception History
Isaiah 28:17 has been read in several ways across church history. Early Christian writers, such as Cyril of Alexandria, connected the line and plummet to Christ as the exact measure of righteousness. In the Reformation, Calvin used the verse to argue that God would restore the true church by his standard, not human tradition. The reformers saw the papacy as a refuge of lies that would be swept away by the gospel. The Jewish commentator Kimchi (12th-13th century) interpreted the verse as referring to the righteous reign of Hezekiah. In Protestant hymnody, the imagery of the sure foundation and the storm of judgment has been used to express both warning and comfort, often paired with Matthew 7:24-27. The verse’s connection to the cornerstone (Christ) has made it a staple in teaching about salvation and judgment.
Preaching This Verse
Three-point outline
- God sets the standard. Justice and righteousness are not optional values; they are the builder’s line and plummet by which everything is measured. God will not bend the rule.
- Human refuges collapse. The hail and waters, God’s judgment, sweep away every hiding place built on lies. No political deal, no religious ritual, no self-deception can stand.
- Only the true foundation holds. The same justice and righteousness that level false refuges are the very qualities that establish the cornerstone of Zion (v. 16). Believers are built into that building; scoffers are swept away.
Five-point outline
- The scoffers’ false confidence. They had made a covenant with death and hidden in lies (v. 15). The text exposes the foolishness of trusting in anything but God.
- The cornerstone laid in Zion. God himself provides a sure foundation for those who believe (v. 16). Christ is that cornerstone (1 Peter 2:6).
- The measuring line of justice. God’s justice is the exact standard that tests every life and every nation. It is both a promise for the faithful and a threat to the rebellious.
- Demolition by hail and flood. The storm of divine judgment sweeps away the refuge of lies. What seemed secure is gone in an instant.
- The call to believe. The passage invites hearers to abandon false refuges and rest on the cornerstone, where justice and righteousness meet in mercy.
Illustration hooks
- A carpenter uses a spirit level to check a wall. A wall that looks fine to the eye can be dangerously crooked. God’s level reveals what we cannot see, the hidden lies we trust.
- People sometimes build houses on floodplains because the view is nice. When the waters rise, the house is swept away. The scoffers had built their security on something that would not survive the storm.
- A counterfeit shelter, like a cardboard box in a hurricane, may look like protection for a moment but offers no real safety. Our self-made refuges are equally fragile before God’s judgment.
Questions your congregation is asking
- How do I know if I am building my life on the true foundation or on a refuge of lies?
- Is it possible to have false security even while being religious? What might that look like in my own life?
- What does it mean that God’s justice and righteousness are both a promise and a threat? Can I experience them as mercy rather than judgment?
Leading a Discussion
This verse shows how God’s justice and righteousness function as an exact standard. They build up those who trust in the cornerstone, but they sweep away every false refuge. As you read Isaiah 28:14-22, notice how the sober warning is wrapped in a promise: God himself has laid a sure foundation. Use these questions to explore both the warning and the hope.
Discussion questions
- Observation: What does verse 15 say the rulers of Jerusalem were trusting in? How did they describe their supposed security?
- Observation: In verse 17, what two building tools does God say he will use? What are they normally used for in construction?
- Interpretation: The line and plummet could be used for both building and demolition. How does that double function help us understand God’s work in this passage?
- Interpretation: The verse says the hail will sweep away the refuge of lies. What does that phrase tell us about the nature of false security?
- Connection: How does verse 16 (the cornerstone) relate to verse 17? Is the standard of justice and righteousness good news or bad news for the person who believes?
- Application: What are some modern “refuges of lies”, things people trust in instead of God? How can we recognize them in our own hearts?
- Application: In what area of your life do you need to let God’s line and plummet check your building? What would it look like to realign with his justice and righteousness?

What the Commentators Say
10 public-domain commentaries, condensed into plain language.
Barnes' Notes on the Bible Protestant 1832
Barnes emphasizes that God will judge with the same exactness a carpenter uses his measuring line and plummet. Every action will be measured against the strict standard of law, with no mercy intermingled in the verdict. Hail and floods then picture the terrible force of that unsparing judgment.
Calvin's Commentaries Reformed 1564
Calvin argues that God will restore the church with the same precision a builder uses a line and plummet, applying exact judgment and righteousness. This image confronts those who boast of being pillars while the church lies in ruins, showing that only God's measured reformation can rebuild what human pride has destroyed.
Cambridge Bible for Schools and Colleges Anglican 1880
The commentator identifies judgment and righteousness as the builder's line and plummet, the unchanging standard for political conduct. Actions not grounded in faith in Jehovah and conforming to this divine rule are a false refuge that will be swept away like hail.
Geneva Bible Notes Reformed 1599
The Geneva Bible notes draw attention to God's judgment as a precise measuring tool, a rule and balance that exposes the worthlessness of human confidence. Where people trust in false refuges or hidden securities, God's judgment sweeps them away like hail and floods, leaving no hiding place.
Gill's Exposition of the Bible Baptist 1748
Gill reads the line and plummet as God's righteous judgment applied to the spiritual building where Christ is the foundation. He insists this prophecy points to Christ, not Hezekiah, and that the hail and waters sweeping away false refuges represent avenging justice, likely the Roman army.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB explains that God's judgment is as exact as a builder's measuring line and plummet. While Christ the cornerstone offers grace to believers, those who scoff face judgment measured by the precise standard of God's justice, reinforced by the image of hail as divine punishment.
Keil & Delitzsch OT Commentary Protestant 1876
Keil-Delitzsch stresses that the promise of a foundation stone in Zion is actually a threat to Jerusalem's rulers. What sounds like hope becomes a danger because it offers safety only to those who believe, while unbelievers will be crushed by it. The cornerstone is the Messiah, not Hezekiah, and faith alone determines the outcome.
Lange's Commentary Reformed 1857
Lange identifies the foundation stone laid in Zion as the personal Messiah, the Logos, contrasting it directly with the false refuge of political cunning and diplomatic lies that the scoffing rulers trust in. Only faith in this true foundation provides security, while their covenant with death will be annulled.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry's main point is that mocking God's judgments is as serious an offense as mocking His word. Those who trust in false agreements and earthly refuges are defying the very God who will sweep away every refuge, leaving only the sure foundation He Himself lays in Zion.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley stresses that the plumb line in judgment does double duty: it measures both what stands and what falls. Those who reject the cornerstone are marked for demolition, an exact and severe punishment carried out with the same precision used in building.
