“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.”
King James Version (KJV)
26:1 In that day - When God shall do such glorious works, as are described in the foregoing chapter. Sung - In the church of God. A city - Jerusalem, or the church, which is often compared to a city. For walls - God's immediate and saving protection shall be to his church instead of walls.
