Isaiah 26:12

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).

The prophet in these verses looks back upon what God had done with them, both in mercy and judgment, and sings unto God of both, and then looks forward upon what he hoped God would do for them. Observe, I. His reviews and reflections are mixed. When he looks back upon the state of the church he finds, 1. That God had in many instances been very gracious to them and had done great things for them. (1.) In general (Isa 26:12): Thou hast wrought all our works in us, or for us. Whatever good work is done by us, it is owing to a good work wrought by the grace of God in us; it is he that puts good thoughts and affections into our hearts if at any time they be there, and that works in us both to will and to do of his good pleasure. Acti, agimus - Being acted upon, we act. And if any kindness be shown us, or any of our affairs be prosperous and successful, it is God that works it for us. Every creature, every business, that is in any way serviceable to our comfort, is made by him to be so; and sometimes he makes that to work for us which seemed to make against us. (2.) In particular (Isa 26:15): "Thou hast increased the nation, O Lord! so that a little one has become a thousand (in Egypt they multiplied exceedingly, and afterwards in Canaan, so that they filled the land); and in this thou art glorified," for the multitude of the people is the honour of the prince, and therein God was glorified as faithful to his covenant with Abraham, that he would make him a father of many nations. Note, God's nation is a growing nation, and it is the glory of God that it is so. The increase of the church, that holy nation, is therefore to be rejoiced in because it is the increase of those that make it their business to glorify God in this world. 2.
