Y será que en aquel tiempo la gloria de Jacob se atenuará, y enflaqueceráse la grosura de su carne.
E será naquele dia, que a glória de Jacó se definhará, e a gordura de sua carne emagrecerá;
En ce jour, la gloire de Jacob sera affaiblie,
Zu der Zeit wird die Herrlichkeit Jakobs dünn sein, und sein fetter Leib wird mager sein.
En het zal geschieden te dien dage, dat de heerlijkheid van Jakob verdund zal worden, en dat de vettigheid van zijn vlees mager worden zal.
In quel giorno, la gloria di Giacobbe sarà menomata, e la pinguedine del suo corpo dimagrerà.
I stanie się dnia onego, że umniejszona będzie sława Jakóbowa, a tłustość ciała jego schudnie.
И будет в тот день: умалится слава Иакова, и тучное тело его сделается тощим.
到 那 日，雅各 的榮耀 必至枵薄；他肥胖 的身體 必漸瘦弱。
And it will be in that day that the glory of Jacob will be made small, and the strength of his body will become feeble.

Scholars' Consensus
Commentators agree that 'Jacob' here denotes the northern kingdom of Israel, not the patriarch personally. Barnes calls it 'the kingdom of Israel, or Samaria,' and Gill specifies 'the ten tribes.' Calvin notes that the title probably refers to the ten tribes alone, though he considers whether it might include all the elect people. The 'glory' is 'dignity, power; that on which they relied, and of which they boasted' (Barnes). The verb yiddal (from דָּלַל, to languish) is a Niphal, a passive construction meaning 'be made low.' A body wastes away. Gill pictures a man in a consumption, reduced to 'skin and bones.' The Cambridge Bible calls the image 'enfeebled.' All commentators agree the judgment is simultaneous with the fall of Damascus (v.3) because of Israel's alliance with Syria. The prophecy points beyond the ruin: Keil and Delitzsch see here 'the law of Israel's history', a remnant will return (v.6). Calvin connects the 'fatness' to the rebuke of indolence and pride (Jer 5:28; Amos 4:1). What is clear across traditions: God is reducing a boastful people to the point of repentance.
How settled is the interpretation?
Interpretive difficulty: Low
What is clear: The metaphor describes God's judgment on Israel through a wasting away of their glory and prosperity, leading to a remnant that repents and returns to the Lord.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Identity of 'Jacob' | Refers to the nation descended from the patriarch Jacob. | Most commentators (Barnes, Gill, Calvin) say it refers to the ten tribes of the northern kingdom. Keil and Delitzsch see it as encompassing all Israel. |
| Meaning of 'in that day' | A definite time of judgment that happens alongside the fall of Damascus. | The supplied sources consistently read it as the historical Assyrian invasion (c. 722 BC). There is no supplied evidence for an apocalyptic reading, though some traditions may extend it symbolically. |
| Metaphor of 'fatness of his flesh' | Symbolizes prosperity, self-indulgence, and pride. | Gill and the Targum understand it literally as wealth and riches being carried away. Calvin emphasizes spiritual indolence and arrogance (connecting to 'fat cows' in Amos 4:1). |
| Purpose of judgment | It is punishment for sin and is not the final word; a remnant remains. | Some (Matthew Henry, Calvin) stress the redemptive outcome, repentance and return to God. Others (Clarke, Barnes) focus on the severity of the national disaster, though they still note the remnant. |
Historical & Cultural Context
Isaiah 17 opens the 'burden of Damascus.' By the late eighth century BC, Syria (centered on Damascus) and the northern kingdom of Israel (called Ephraim or Jacob) had formed a military alliance against the rising power of Assyria. This coalition is the backdrop of the Syro-Ephraimite crisis (cf. Isa 7, 8). Isaiah pronounces judgment on both partners: the fortress of Ephraim and the kingdom of Damascus will cease (v.3). Verse 4 then pivots exclusively to Israel.
In ancient Near Eastern culture, 'fatness' was a symbol of divine blessing, prosperity, and strength. Israel had grown wealthy under Jeroboam II; Deuteronomy 32:15 warns that when Jeshurun 'grew fat, he kicked.' The metaphor of a body wasting away reverses that blessing. The Hebrew verb יֵרָזֶה (yerazeh, from רָזָה, to starve) appears only here and in Isaiah 10:16 (where the Lord sends 'leanness among his fat ones'). The lexicon gives the Niphal meaning 'be made lean,' emphasizing divine agency.
The agricultural imagery that follows (vv.5, 6) was vivid for Isaiah's hearers. The valley of Rephaim, southwest of Jerusalem, was known for its rich wheat fields. A harvest that leaves only a few scattered grains, or an olive tree beaten until only two or three berries remain in the highest branches, that is the severity of the coming judgment. Yet even this image carries hope: at least a gleaning remains. The purpose is not annihilation. As Keil and Delitzsch note, the remnant is the hinge: the same people who are judged will later 'look to their Maker' (v.7) and abandon false altars (v.8).
Textual Notes
The consulted sources note no significant textual variants for Isaiah 17:4. The Hebrew text is stable across the manuscript traditions represented by the supplied commentaries.
Reception History
Jewish exegete David Kimchi (cited by Adam Clarke) understood 'the glory of Jacob' as the ten tribes carried into captivity. John Calvin, in his 1564 commentary, read the verse as a rebuke to Israel's 'indolence' and pride, a theme he traced through the prophets. Later Reformed and Protestant interpreters, such as Matthew Henry and Adam Clarke, preached it as a warning against trusting in human alliances and as a call to humble repentance. The verse has appeared in sermons and devotional writings as a reminder that God's judgments leave a remnant, pointing forward to the hope of restoration (vv.7, 8). It is less frequently cited in liturgical contexts but has shaped the church's understanding of divine discipline and the frailty of human glory.
Preaching This Verse
Three-point outline
- The Glory That Fades. Israel's pride in wealth, numbers, and alliances, the 'glory of Jacob', is made thin. It contracts like a body with a wasting disease. Human boasting cannot stand before the Lord.
- The Body That Wastes. The 'fatness of his flesh' becomes lean. What once signified blessing now signals judgment. Spiritual decline often manifests as a slow, unnoticed erosion of reliance on God.
- The Harvest That Leaves a Remnant. The judgment is severe but not final. Gleanings remain (v.6). The humbled people turn back to the Maker (vv.7, 8). God's discipline clears ground for repentance.
Five-point outline
- Alliance with the world brings shared judgment: Israel joined Damascus and shares its fate (v.3).
- God opposes the proud: the 'fat' who trust in their own strength are brought low (Deut 32:15).
- No human glory can withstand the Lord's 'leanness' (Isa 10:16).
- Judgment reduces to a remnant, a few olives left on the branch (v.6).
- The end goal is repentance, not ruin: people look to their Maker, not to altars of their own making (vv.7, 8).
Illustration hooks
- A once-thriving family business that collapses because of overreach and refusal to adapt, pride distorts judgment, and what seemed solid becomes thin.
- The physical experience of a wasting illness: the slow loss of strength and flesh works as a metaphor for spiritual decline over years of neglecting prayer and community.
- An orchard after harvest: a few olives overlooked in the high branches, enough to preserve the species. The remnant is small but carries the future.
Questions your congregation is asking
- Does God still judge nations today, or is that only an Old Testament pattern?
- When my life feels like it is 'wasting away,' is that God's discipline or just bad circumstances?
- How do I know if the 'glory' I am pursuing is my own or God's?
Leading a Discussion
This verse uses vivid bodily imagery to describe the judgment of God on a proud people. As you discuss, consider how the metaphor of wasting flesh helps us understand sin's consequence and God's purpose in discipline. Let the promise of a remnant (vv.5-6) and the turning of hearts (vv.7-8) shape your conversation about hardship.
Discussion questions
- What does the phrase 'glory of Jacob' mean in this context? What did Israel glory in?
- Why does God use the metaphor of a body wasting away to describe judgment? What feelings does that image evoke in you?
- Read Deuteronomy 32:15. How does that earlier warning prepare us for this prophecy?
- Isaiah 10:16 uses similar language of 'fat ones' and 'leanness.' What does this repeated imagery tell us about God's attitude toward pride?
- The judgment comes together with Syria (v.3). Why would God judge both the enemy and His own people? What does that say about God's impartiality?
- Look ahead to vv.7-8. What is the intended outcome of this judgment? How does that shape your understanding of hardship in your own life?
- In what areas of life (personal, church, national) might we be trusting in 'fatness' rather than in the Lord? How can you repent and turn back this week?

What the Commentators Say
10 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke identifies "that day" as the specific historical moment when the ten tribes of Israel—whom he calls the glory of Jacob—were taken into captivity. He follows the Jewish commentator Kimchi in reading the verse as a direct prophecy of that national disaster.
Barnes' Notes on the Bible Protestant 1832
Barnes identifies the glory of Jacob as the power and wealth in which the kingdom of Israel boasted. He reads the thinning as a wasting away like a body consumed by disease, not just a loss but a gradual decay. The two images of emaciation and a stripped harvest reinforce the same point: what they trusted in will wither.
Calvin's Commentaries Reformed 1564
Calvin sees irony in Isaiah calling the ten tribes of Israel glorious. Their alliance with Syria made them proud, but God mocks their imagined strength by threatening to strip away the very prosperity that puffed them up. Their fatness will become lean.
Cambridge Bible for Schools and Colleges Anglican 1880
This commentator reads the passage as a three-picture prophecy of Ephraim's decline: a wasting disease, the reaping of a cornfield, and the gleaning of olives after harvest. The "glory of Jacob" is not spiritual but material—might, population, and prosperity—all reduced to near nothing.
Geneva Bible Notes Reformed 1599
And in that day the glorie of Iaakob shall be impouerished, and the fatnes of his flesh shalbe made leane.
Gill's Exposition of the Bible Baptist 1748
Gill reads the thinning and wasting of Jacob as a consuming disease that strips Israel of its former glory. He pictures the ten tribes reduced like a man in consumption, their numerical strength and material riches carried away until only skin and bones remain.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB identifies the glory of Jacob as the northern kingdom of Ephraim and everything they placed their trust in. The image of fatness turning to lean points to God's judgment stripping away their prosperity and strength, as seen in the earlier prophecy against Assyria.
Keil & Delitzsch OT Commentary Protestant 1876
Keil-Delitzsch identifies the remnant principle as the fixed law of Israel's history: judgment reduces the nation to a tiny gleaning, but that purified remnant then looks only to its Creator. They specify that
Lange's Commentary Reformed 1857
Lange sees the prophecy as tracing Ephraim's decline to near extinction through three images, but the point is the remnant that survives. That tiny gleaning, not the destruction, is the focus because it will turn to God and abandon idols, a process he says still continues.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry draws attention to the shared cup of judgment: because the ten tribes are allied with Syria, they must drink the same bitter draught. He pictures Damascus reduced to rubble and its country towns abandoned to flocks, noting that such desolation is what sin brings upon proud cities.
