Scholars' Consensus
Commentators agree that this verse belongs to a section of hope within Isaiah's oracle against Egypt (vv. 1-17). After judgment, conversion is promised. The Hebrew verbs yihyu (they will be) and yenamer (it will be called) are imperfect, pointing to a future reality.
There is broad agreement that 'speaking the language of Canaan' symbolizes adopting the worship of Yahweh. Barnes notes that the phrase is akin to Zephaniah 3:9, where a 'pure language' is given to those who call on the Lord. Swearing to Yahweh (Deuteronomy 10:20) indicates covenant commitment.
The main debate concerns the number 'five' and the name of one city. Matthew Henry, Calvin and Gill take 'five' as an indefinite number representing several cities. The Cambridge Bible, however, reads it as a definite number, possibly referring to specific Jewish colonies. On the city's name, the Masoretic Text reads 'Ir ha-Heres (city of destruction), but many ancient witnesses (Symmachus, Vulgate, Targum) read 'Ir ha-Cheres (city of the sun). The Septuagint alters it to 'city of righteousness'. Keil and Delitzsch argue the reading 'destruction' may be a scribal change born of later Jewish hostility toward the temple at Leontopolis. Despite these textual questions, all traditions see the verse as a promise that Egypt will come to know Yahweh.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Literal Jewish colonies: 'Five cities' refers to actual Egyptian towns with Jewish populations; the prophecy was fulfilled in the Hellenistic period (Cambridge Bible, some Jewish sources).
- Indefinite conversion: 'Five' is a round number; the prophecy speaks generally of Egypt's turning to Yahweh, not a precise geography (Calvin, Matthew Henry, Gill).
- 'City of destruction' as original & symbolic: The MT reading haheres (destruction) is original; the name is a pun or nickname for Heliopolis indicating that its idolatry will be destroyed (Keil & Delitzsch, Lowth via Clarke).
- 'City of the sun' as original & literal: The variant hacheres (sun) is the better reading; the city is Heliopolis, and the prophecy points to its conversion (Symmachus, Vulgate, many modern scholars).
What is clear: Regardless of the textual or numerical specifics, the verse declares that Egyptians will come to know Yahweh, speak His language, and bind themselves to Him in covenant — a vision of hope for the nations.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Number of cities ('five') | The number indicates a limited number of Egyptian cities that will turn to Yahweh, in contrast to the many cities of Egypt. | Some (Barnes, Calvin, Matthew Henry) take 'five' as an indefinite round number meaning 'several'; others (Cambridge Bible) see it as a specific number, possibly referencing five actual Jewish colonies (e.g., Migdol, Tahpanhes, Noph, Pathros, Heliopolis). |
| Name of the city: 'Destruction' vs. 'Sun' | The verse names one city that will be specially called something; the context requires the name to align with the hopeful fulfillment. | The Masoretic Text reads 'city of destruction' (ההרס). Many ancient witnesses (Symmachus, Vulgate, Targum) read 'city of the sun' (החרס). Some scholars argue the Masoretic reflects a later Jewish alteration to discredit Onias' temple; others hold it original, with 'destruction' referring to the overthrow of idolatry (Gill) or as a pun on Heliopolis. |
| Historical fulfillment | The prophecy looks forward to a time when Egyptians worship Yahweh; this began to happen with the Jewish diaspora in Egypt. | Jewish tradition (Talmud Menachot 110a) applied it to Onias' temple at Leontopolis/Heliopolis. Christian interpreters (Matthew Henry, Jamieson-Fausset-Brown) see partial fulfillment in the spread of the gospel to Egypt via Mark and others, with full realization still future. |
| 'Language of Canaan' meaning | This phrase indicates adoption of Jewish religious identity. | Some (Barnes) see it literally as speaking Hebrew; others (Cambridge Bible) see a symbolic meaning: using the speech of God's people as an expression of shared faith. |
Historical & Cultural Context
Isaiah 19 sits within a series of oracles against the nations. The first seventeen verses describe Egypt's devastation: civil war, a harsh ruler, dried-up Nile, and confusion sent by Yahweh (vv. 14-15). Then the tone shifts sharply. Verse 18 begins 'In that day', a phrase Isaiah uses for an indefinite future time of divine intervention (cf. 2:11; 11:11).
Egypt had long been a place of refuge and danger for Israel. Abraham, Joseph, and later Jeremiah all had dealings there. By the time Isaiah wrote (8th century BC), Egypt was a major power but also a source of idolatry. The prophecy that Egyptians would speak 'the language of Canaan' (Hebrew) and swear loyalty to Yahweh envisions a complete religious reversal.
Historically, Jewish communities did settle in Egypt after the fall of Jerusalem (586 BC) and later under Persian rule. In the 2nd century BC, the high priest Onias IV built a temple at Leontopolis (in the Heliopolite nome) claiming Isaiah 19:18-19 as prophetic warrant. Some scholars (e.g., the Cambridge Bible) think the prophecy envisions exactly such Jewish colonies maintaining their language and faith. Others (Barnes, Calvin) see it as a symbol of genuine conversion among native Egyptians.
The reference to 'five cities' likely reflects the reality of scattered Jewish settlements in the Nile Delta. The number may be literal (five known colonies) or a round number indicating a fragmentary beginning, 'a day of small things'. The naming of one city as 'the city of destruction' (or 'sun') probably alludes to Heliopolis (On), a center of sun-worship, whose name the prophet may have twisted to indicate the overthrow of idolatry.
Textual Notes
The key textual issue in this verse is the name of the city: haheres (destruction) vs. hacheres (sun). The Masoretic Text (supported by many codices and the Masora) has ההרס (hahares), meaning 'the destruction'. However, Symmachus, the Vulgate (Jerome), Targum Jonathan, and some Hebrew manuscripts read החרס (hacheres), meaning 'the sun'. The Septuagint gives πολις ασεδέκ ('city of righteousness'), likely a deliberate alteration to apply the prophecy to Onias' temple. The reading 'sun' is widely accepted by scholars as more likely original, with 'destruction' possibly a later scribal change expressing contempt for the rival temple. The supplied sources note no other significant variants in this verse.
Reception History
In the centuries following the prophet, Jewish communities in Egypt read this verse as a promise that their worship was legitimate. The historian Josephus records that Onias IV, when seeking permission to build a temple at Leontopolis (c. 160 BC), quoted Isaiah 19:18-19 to argue that the site was foretold. The Talmud (Menachot 110a) identifies the city as the 'city of the sun,' confirming that Jewish tradition associated the verse with Heliopolis.
Early Christian commentators, including Jerome, understood the 'city of the sun' as Heliopolis and saw the verse as a prophecy of the eventual conversion of Egypt to Christianity. They pointed to the presence of an early Christian community in Alexandria as a partial fulfillment. Throughout church history, the verse has been a favorite text for missions, emphasizing that God's salvation reaches beyond ethnic Israel to the nations.
Preaching This Verse
Three-point outline
- Judgment leads to repentance: The preceding verses describe Egypt's humbling; now they turn to Yahweh. Suffering can prepare the heart for grace.
- Conversion changes speech and allegiance: Speaking the language of Canaan means embracing the God of Israel. Swearing to Yahweh is personal covenant (Deut 10:20). True faith reshapes both words and commitments.
- Even a small beginning is God's work: Five cities out of many, a remnant. The gospel often starts small before spreading. The 'city of destruction' (or 'city of the sun') is transformed from a center of false worship into a place that honors Yahweh.
Five-point outline
- Context matters: This verse is embedded in an oracle that begins with judgment (Isa 19:1-17). The hearer must understand the bad news to appreciate the good.
- An indefinite number: 'Five' is likely a round number representing several cities. The point is that enough Egyptians will convert to form worshipping communities.
- Language of worship: 'Language of Canaan' is more than linguistic; it signals a shared identity around Yahweh's word. Zephaniah 3:9 echoes this promise.
- Covenant commitment: Swearing to Yahweh implies exclusive loyalty. Nehemiah 10:29 shows how this oath bound Israel; here Egyptians enter the same bond.
- A transformed city: Whether 'destruction' (referring to judgment on idolatry) or 'sun' (the ancient name of Heliopolis), the city is renamed to reflect its new purpose. God renames what He redeems.
Illustration hooks
- A local school that was once a troubled site becomes the location of a thriving food bank and community center. The name 'dangerous crossroads' becomes 'Hope Square'.
- Someone who grew up speaking a different language moves to a new country, learns the language, and that new tongue becomes the marker of their new citizenship.
- A church plant in a neighborhood known for crime or secularism; after years of faithful presence, the neighborhood's reputation begins to shift.
Questions your congregation is asking
- Does God really love people outside of Israel? Can He save them?
- What does it mean for a whole city or nation to be converted? Does this happen now or only at the end?
- Why does the prophecy mention a city called 'destruction'? Is that good or bad?
Leading a Discussion
This verse follows a long section of judgment against Egypt. Suddenly the tone changes. God promises that some Egyptians will adopt Hebrew speech and swear loyalty to Him. One city even gets a new name. Use these questions to help your group see how God's mercy reaches beyond Israel.
Discussion questions
- Read Isaiah 19:1-17 first. What picture do you get of Egypt's condition? How does verse 18 feel different?
- What does 'speak the language of Canaan' mean in this context? Why would language matter for faith?
- The Hebrew word for 'swear' (nishba'ot) is a strong verb of commitment. How is this like or unlike baptism or confirmation in your tradition?
- Why do you think the number 'five' is used? Some say it is a literal number, others a round number. What difference does the interpretation make?
- The city is called 'destruction' in our Bibles, but many ancient versions say 'city of the sun.' Which reading seems more likely to you, and why?
- How does this prophecy relate to the temple in Leontopolis (built by Onias IV around 160 BC)? Does that historical event fulfill the prophecy, or is something greater still to come?
- In what ways does God still 'rename' places or people today? Can you think of an example from your own community?

What the Commentators Say
10 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke highlights a major textual uncertainty in this verse: some manuscripts read "city of the sun," while others read "city of destruction." He notes that the Jewish priest Onias used the first reading to justify building a temple in Egypt, and later Jews may have changed it to the second out of contempt for that schismatical temple.
Barnes' Notes on the Bible Protestant 1832
Barnes notes a longstanding textual debate over whether the Hebrew word should be read "destruction" or "sun." He argues that Isaiah's main point was simply to foretell that several Egyptian cities would convert to the true God, with one particular city being saved from destruction. The later claim by Onias that this predicted Heliopolis was likely an artful misuse.
Calvin's Commentaries Reformed 1564
Calvin argues that the "five cities" does not name a literal number or a specific place like Heliopolis. Instead, the phrase expresses a proportion: five out of every six cities will survive the judgment, showing that God's restoration will be widespread and merciful, not limited to a small handful.
Cambridge Bible for Schools and Colleges Anglican 1880
This commentator argues that the five cities speaking Hebrew are best understood as Jewish colonies in Egypt that preserved their language and religion, not as a gradual conversion of Egyptian cities. He also examines whether the final city is called Destruction, Sun, or Righteousness, favoring the reading City of the Sun as most natural.
Geneva Bible Notes Reformed 1599
The Geneva note highlights a textual ambiguity: the Hebrew word for destruction can also be read as sun. This suggests the verse may refer to Heliopolis, the Egyptian city of the sun, rather than a city of literal destruction.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB reads this passage as a prophecy that suffering leads to repentance, uniting former enemies Egypt, Assyria, and Israel in a common faith. The "language of Canaan" refers to embracing the religion of revelation, a unity yet to be fully realized. He also notes a textual issue: "city of destruction" may refer to the site of Onias’ rival temple.
Keil & Delitzsch OT Commentary Protestant 1876
Keil and Delitzsch see the name Ir ha-Heres as a deliberate wordplay on the actual name of Heliopolis (sun-city). They argue it does not mean literal destruction but rather the demolition of idolatry: the great center of sun-worship will become the city where pagan altars are thrown down.
Lange's Commentary Reformed 1857
Lange emphasizes that the five cities are not a tiny beginning but represent that Egypt's conversion has already reached the halfway point. The prophecy culminates in a peaceful highway between Egypt and Assyria, with Israel as their equal third partner. God blesses all three with honored titles, but Israel alone retains the special name of His inheritance.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry sees God's mercy toward Egypt not in restoring its worldly prosperity but in bringing true religion there. The real blessing is that Egyptians will come to worship the one true God, a grace far greater than any earthly enrichment Egypt ever knew.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley reads the five cities as an indefinite yet representative number of major centers that will convert to the Jewish faith in gospel times. He draws a sharp contrast: the sixth city, singled out by the word "one," stands for those cities that remain impenitent and are destroyed rather than saved.
