إشعياء ٢٦:١

Thus the second hymnic echo has its confirmation in a prophecy against Moab, on the basis of which a third hymnic echo now arises. Whilst on the other side, in the land of Moab, the people are trodden down, and its lofty castles demolished, the people in the land of Judah can boast of an impregnable city. "In that day will this song be sung in the land of Judah: A city of defence is ours; salvation He sets for walls and bulwark." According to the punctuation, this ought to be rendered, "A city is a shelter for us;" but עז עיר seem rather to be connected, according to Pro 17:19, "a city of strong, i.e., of impregnable offence and defence." The subject of ישׁית is Jehovah. The figure indicates what He is constantly doing, and ever doing afresh; for the walls and bulwarks of Jerusalem (chēl, as in Lam 2:8, the small outside wall which encloses all the fortifications) are not dead stone, but yeshuâh, ever living and never exhausted salvation (Isa 60:18). In just the same sense Jehovah is called elsewhere the wall of Jerusalem, and even a wall of fire in Zac 2:9 - parallels which show that yeshuâh is intended to be taken as the accusative of the object, and not as the accusative of the predicate, according to Isa 5:6; Psa 21:7; Psa 84:7; Jer 22:6 (Luzzatto).

To the prophecies of gospel grace very fitly is a song annexed, in which we may give God the glory and take to ourselves the comfort of that grace: In that day, the gospel day, which the day of the victories and enlargements of the Old Testament church was typical of (to some of which perhaps this has a primary reference), in that day this song shall be sung; there shall be persons to sing it, and cause and hearts to sing it; it shall be sung in the land of Judah, which was a figure of the gospel church; for the gospel covenant is said to be made with the house of Judah, Heb 8:8. Glorious things are here said of the church of God. I. That it is strongly fortified against those that are bad (Isa 26:1): We have a strong city. It is a city incorporated by the charter of the everlasting covenant, fitted for the reception of all that are made free by that charter, for their employment and entertainment; it is a strong city, as Jerusalem was, while it was a city compact together, and had God himself a wall of fire round about it, so strong that none would have believed that an enemy could ever enter into the gates of Jerusalem, Lam 4:12. The church is a strong city, for it has walls and bulwarks, or counterscarps, and those of God's own appointing; for he has, in his promise, appointed salvation itself to be its defence. Those that are designed for salvation will find that to be their protection, Pe1 1:4. II. That it is richly replenished with those that are good, and they are instead of fortifications to it; for the inhabitants of Jerusalem, if they are such as they should be, are its strength, Zac 12:5. The gates are here ordered to be opened, that the righteous nation, which keeps the truth, may enter in, Isa 26:2. They had been banished and driven out by the iniquity of t…

26:1-21 This section of the Little Apocalypse (see study note on 24:1–27:13) is a song of praise and a prayer for redemption. 26:1-6 The new community of God’s people is likened to the citizens of a city, securely held together by the Lord. They are righteous, faithful, peaceful, and trusting. 26:1 Our city refers to Zion, the eternal city of God, where the Lord is present to protect and bless his people (see 1:8, 27; see also Ps 46). Zion stands in direct contrast to the “mighty cities” of the nations (Isa 25:2; 26:5), which are helpless and are brought down to “ruins.” • The walls of God’s salvation protectively enclose his people; no one can hurt them again.
