Isaiah 26:1

In that day shall this song be sung in the land of Judah; We have a strong city; salvation will God appoint for walls and bulwarks.

As the overthrow of the apostate faction is described in the close of Isaiah 25:1, so the peace of the faithful is here described under the image of a well-fortified city. The whole context, connected as it is with Christ's coming to destroy death (), cannot admit of the restoration from Babylon under Cyrus being its ultimate and exhaustive fulfillment.

In that day - the day of the Lord's appearing (Isaiah 25:6).

Shall this song be sung in the land of Judah. Therefore the Jews shall have been by that time restored to their own "land."

Strong city - Jerusalem, strong in Yahweh's protection: type of the new Jerusalem (Psalms 48:1), contrasted with the overthrow of "the lofty city" of the ungodly foe, (Isaiah 26:4; Isaiah 12:1; Isaiah 13:1; Isaiah 14:1; Revelation 21:10; ; Revelation 22:10, etc.)

Salvation will (God) appoint (for) walls and bulwarks - (; Isaiah 33:20; ; .)

Bulwarks - the trench with the antemural earth-works exterior to the wall.
