Jesaja 26:13

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).

This chapter is a song of holy joy and praise, in which the great things God had engaged, in the foregoing chapter, to do for his people against his enemies and their enemies are celebrated: it is prepared to be sung when that prophecy should be accomplished; for we must be forward to meet God with our thanksgivings when he is coming towards us with his mercies. Now the people of God are here taught, I. To triumph in the safety and holy security both of the church in general and of every particular member of it, under the divine protection (Isa 26:1-4). II. To triumph over all opposing powers (Isa 26:5, Isa 26:6). III. To walk with God, and wait for him, in the worst and darkest times, Isa 26:7-9). IV. To lament the stupidity of those who regarded not the providence of God, either merciful or afflictive (Isa 26:10, Isa 26:11). V. To encourage themselves, and one another, with hopes that God would still continue to do them good (Isa 26:12, Isa 26:14), and engage themselves to continue in his service (Isa 26:13). VI. To recollect the kind providences of God towards them in their low and distressed condition, and their conduct under those providences (Isa 26:15-18). VII. To rejoice in hope of a glorious deliverance, which should be as a resurrection to them (Isa 26:19), and to retire in the expectation of it (Isa 26:20, Isa 26:21). And this is written for the support and assistance of the faith and hope of God's people in all ages, even those upon whom the ends of the world have come.
