Isaiah 26:1 - Exposition

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" (verse 2), but no "walls"— walls and bulwarks being unnecessary, since the saving might of God himself would be its sure defense against every enemy.
