26:1 In that day shall {a} this song be sung in the land of Judah; We have a strong city; {b} salvation will [God] appoint [for] walls and bulwarks.
(a) This song was made to comfort the faithful when their captivity would come, assuring them also of their deliverance, for which they should sing this song.
(b) God's protection and defence will be sufficient for us.
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.
26:1-4 That day, seems to mean when the New Testament Babylon shall be levelled with the ground. The unchangeable promise and covenant of the Lord are the walls of the church of God. The gates of this city shall be open. Let sinners then be encouraged to join to the Lord. Thou wilt keep him in peace; in perfect peace, inward peace, outward peace, peace with God, peace of conscience, peace at all times, in all events. Trust in the Lord for that peace, that portion, which will be for ever. Whatever we trust to the world for, it will last only for a moment; but those who trust in God shall not only find in him, but shall receive from him, strength that will carry them to that blessedness which is for ever. Let us then acknowledge him in all our ways, and rely on him in all trials.
