In that dayThis phrase often refers to a future time of fulfillment or divine intervention. It is a prophetic term used throughout the Bible to indicate a significant event in God's plan. In Isaiah, it frequently points to the coming of the Messiah and the establishment of His kingdom.
this song will be sung
Songs in the Bible are often used to celebrate God's deliverance and faithfulness. This particular song is a prophetic declaration of victory and salvation. It echoes the tradition of songs like the Song of Moses (Exodus 15) and the Psalms, which celebrate God's mighty acts.
in the land of Judah
Judah was the southern kingdom of Israel, known for its capital, Jerusalem. This region holds significant biblical history, being the tribe from which King David and ultimately Jesus Christ descended. The land of Judah is central to many prophecies concerning the Messiah and God's covenant with His people.
We have a strong city
The "strong city" symbolizes security and divine protection. In biblical times, cities with strong walls were seen as safe havens. This imagery points to the spiritual security found in God's kingdom, which is unassailable by earthly powers.
salvation is established
Salvation here is depicted as a permanent and unshakeable foundation. This reflects the biblical theme of God as the ultimate source of salvation, a recurring message in both the Old and New Testaments. It foreshadows the salvation brought through Jesus Christ, who is often referred to as the cornerstone.
as its walls and ramparts
Walls and ramparts were essential for the defense of ancient cities. In a spiritual sense, this imagery conveys the idea that God's salvation provides protection and strength. It aligns with other scriptures that describe God as a fortress and refuge, such asPsalm 18:2.

In that day• Isaiah loves to use this phrase to point to a specific, God-appointed moment when His plans break into history (Isaiah 12:4; 25:9).
• Here it looks forward to the culmination of the Lord’s deliverance—what later prophets call “the day of the LORD” (Zephaniah 3:16-17).
• Because Scripture’s prophecies always come to pass, we can read this as a rock-solid promise, not poetic wishful thinking (Numbers 23:19).
this song will be sung• God’s works naturally call forth worship. After the Red Sea, Moses and Israel “sang this song to the LORD” (Exodus 15:1). When Christ’s victory is complete, heaven breaks into new song (Revelation 5:9).
• Songs fix truth in our hearts; Isaiah is giving Judah—and us—the lyrics ahead of time so faith can rehearse the victory before it arrives (Psalm 40:3).
in the land of Judah• The Lord anchors His promises in real geography. Just as Bethlehem received Messiah’s birth (Micah 5:2;Luke 2:4-7), Judah will receive this anthem of triumph.
• Yet the blessings overflow Gentile boundaries. Isaiah later invites, “Let the peoples renew their strength” (Isaiah 41:1), showing that Judah becomes the launch point for worldwide praise.
We have a strong city• The singers rejoice in a secure, God-given metropolis—far stronger than any walled town of ancient Canaan.
•Hebrews 11:10 recalls Abraham “looking forward to the city with foundations, whose architect and builder is God.” Isaiah is previewing that same enduring refuge (cf.Revelation 21:2).
• This contrasts with earthly cities judged for pride—Babylon inIsaiah 21 or the proud “lofty city” flattened inIsaiah 26:5. Security is found only where the LORD rules (Psalm 46:4-7).
salvation is established as its walls and ramparts• Human fortifications crumble; Jericho’s walls fell flat (Joshua 6:20). Here, salvation itself is the defense.
• The phrase pictures deliverance not merely entering the city but enfolding it: “You shall call your walls Salvation and your gates Praise” (Isaiah 60:18).
• Christ fulfills this image. He is both Savior and shelter: “I am the door; if anyone enters through Me, he will be saved” (John 10:9).
• For the believer, security rests on God’s accomplished redemption, “kept by the power of God through faith for salvation ready to be revealed in the last time” (1 Peter 1:5).
summaryIsaiah 26:1 is a prophetic hymn sheet handed to God’s people in advance. It promises a coming day when Judah—and ultimately all who trust the Lord—will celebrate inside a city whose very walls are made of God’s saving power. Every word underscores our unshakeable hope: God appoints the day, supplies the song, secures the place, and Himself becomes the fortress of our salvation.
XXVI.
(1)In that day shall this song be sung . . .--The prophet appears once more, as inIsaiah 5:1;Isaiah 12:4, in the character of a psalmist, and what he writes is destined for nothing less than the worship of the new city of the heavenly kingdom.
Salvation will God appoint for walls.--Better,salvation He appoints.The walls of the heavenly city are not of stone or brick, but are themselves as a living force, saving and protecting. The same characteristic thought appears inIsaiah 60:18.
Verses 1-18. - A SONG OF THE REDEEMED IN MOUNT ZION. The prophet, having (in
Isaiah 25.) poured forth his own thankfulness to God for the promise of the Church's final redemption and triumph, proceeds now to represent the Church itself in the glorified state as singing praise to God for the same.
Verse 1. -
In that day. In the "day of God" (
2 Peter 3:12), the period of the "restitution of all things" (
Acts 3:21).
In the land of Judah;
i.e. in the "new earth" - whose city will be the "heavenly Jerusalem," and wherein will dwell "the Israel of God" - the antitype whereof the literal "land of Judah" was the type.
A strong city; literally,
a city of strength. In the Revelation of St. John the new Jerusalem is represented as having "a wall great and high" (
Revelation 21:12), and "twelve gates," three on each side. The intention is to convey the idea of complete security. In the present passage the city has "gates" (ver. 2), but no "walls" -
walls and bulwarks being unnecessary, since the saving might of God himself would be its sure defense against every enemy.
