This chapter contains a song of praise for the safety and prosperity of the church, and the destruction of its enemies. The church is represented as a strong city, whose walls and bulwarks are salvation, Isa 26:1 it is said to have gates which are to be opened to a righteous nation, Isa 26:2 its inhabitants, being such who trust in the Lord, are promised perfect peace, Isa 26:3 hence the saints are exhorted to trust in him, Isa 26:4 then follows an account of another city, described as lofty, and its inhabitants as dwelling on high, who are brought down, and trampled on, by the feet of the poor and needy, Isa 26:5 when the prophet returns to the righteous, and asserts their way to be uprightness, because their path is weighed or levelled by God the most upright, Isa 26:7 and in the name of the church declares that they had waited for the Lord in the way of his judgments; and that the desire of their souls was to his name, and the remembrance of it; and that they continued, and would continue, to desire him, and seek after him, seeing righteousness was to be learned by his judgments, Isa 26:8 and though the wicked would not be brought to repentance and reformation by the goodness of God, nor take notice of his hand, yet they should see and be ashamed, and destroyed at last, Isa 26:10 but notwithstanding these judgments of God in the earth, the church professes her faith in the Lord, that he would give her peace and prosperity, from the consideration of what he had wrought for her, and in her, Isa 26:12 and rejects all other lords but him, Isa 26:13 who were dead, and should not live again, but were visited and destroyed, and their memory made to perish, Isa 26:14 but the righteous nation should be increased, though they should meet with trouble, which would cause them to go to the throne of grace, and there pour out their complaints, express their pain and distresses, and the disappointments they had met with, Isa 26:15 to which an answer is returned, promising a glorious resurrection, Isa 26:19 and calling upon the people of God to retire to their chambers for protection in the mean while, until the punishment to be inflicted on the inhabitants of the earth for their sins was over, Isa 26:20.
Ver. 1. In that day shall this song be sung in the land of Judah,.... When great things shall be done: for the church and people of God; and when antichrist and all their enemies are destroyed, as mentioned in the preceding chapter Isa 25:1; then this song shall be sung expressed in this throughout; which the Targum calls a "new" song, an excellent one, as the matter of it shows; and which will be sung in the land of Judah, the land of praise in the congregation of the saints, the professors and confessors of the name of Jesus: in Mount Zion, the church of God below, Ps 149:1:we have a strong city; not an earthly one, as Jerusalem; so the Jewish writers, Jarchi, Aben Ezra, and Kimchi, interpret it; nor the heavenly city, which God has prepared and built, and saints are looking for, and are citizens of: but rather the holy city, the New Jerusalem, described in Re 21:2 or however, the church of Christ, as in the latter day; which will be a "strong" one, being of the Lord's founding, establishing, keeping, and defending; and whose strength will greatly lie in the presence of God, and his protection of it; in the number of its citizens, which will be many, when Jews and Gentiles are converted; and in their union one with another, and the steadfastness of their faith in Christ; when a "small one", as the church is now, shall become a "strong nation", Isa 60:22:salvation will [God] appoint [for] walls and bulwarks; instead of walls, ditches, parapets, counterscarps, and such like fortifications; what they are to cities, that is salvation to the church and people of God; it is their safety and security: as God the Father is concerned in it, it flows from his love, which is unchangeable; it is by an appointment of his, which is unalterable; is secured by election grace, which stands not upon the works of men, but the will of God; and by the covenant of grace, ordered in all things, and sure; and by his power the saints are kept unto it: as Christ is concerned in it, it is as walls and bulwarks; he is the author of it, has completely finished it, and has overcome and destroyed all enemies; his righteousness is a security from all charges and condemnation; his satisfaction a bulwark against the damning power of sin, the curses of the law, and the wrath of God; his mediation and intercession are a protection of saints; and his almighty power a guard about them.
