3 You will keep in perfect peace all who trust in you, all whose thoughts are fixed on you! 4 Trust in the Lord always, for the Lord GOD is the eternal Rock.

5 He humbles the proud and brings down the arrogant city. He brings it down to the dust. 6 The poor and oppressed trample it underfoot, and the needy walk all over it. 7 But for those who are righteous, the way is not steep and rough. You are a God who does what is right, and you smooth out the path ahead of them. 8 Lord, we show our trust in you by obeying your laws; our heart's desire is to glorify your name. 9 In the night I search for you; in the morning I earnestly seek you. For only when you come to judge the earth will people learn what is right. 10 Your kindness to the wicked does not make them do good. Although others do right, the wicked keep doing wrong and take no notice of the Lord 's majesty. 11 O Lord, they pay no attention to your upraised fist. Show them your eagerness to defend your people. Then they will be ashamed. Let your fire consume your enemies.

12 Lord, you will grant us peace; all we have accomplished is really from you.

Matthew Henry's Commentary on Isaiah 26:3-12

Commentary on Isaiah 26:1-4

(Read Isaiah 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.

Commentary on Isaiah 26:5-11

(Read Isaiah 26:5-11)

The way of the just is evenness, a steady course of obedience and holy conversation. And it is their happiness that God makes their way plain and easy. It is our duty, and will be our comfort, to wait for God, to keep up holy desires toward him in the darkest and most discouraging times. Our troubles must never turn us from God; and in the darkest, longest night of affliction, with our souls must we desire him; and this we must wait and pray to him for. We make nothing of our religion, whatever our profession may be, if we do not make heart-work of it. Though we come ever so early, we shall find God ready to receive us. The intention of afflictions is to teach righteousness: blessed is the man whom the Lord thus teaches. But sinners walk contrary to him. They will go on in their evil ways, because they will not consider what a God he is whose laws they persist in despising. Scorners and the secure will shortly feel, what now they will not believe, that it is a fearful thing to fall into the hands of the living God. They will not see the evil of sin; but they shall see. Oh that they would abandon their sins, and turn to the Lord, that he may have mercy upon them.

Commentary on Isaiah 26:12-19

(Read Isaiah 26:12-19)

Every creature, every business, any way serviceable to our comfort, God makes to be so; he makes that work for us which seemed to make against us. They had been slaves of sin and Satan; but by the Divine grace they were taught to look to be set free from all former masters. The cause opposed to God and his kingdom will sink at last. See our need of afflictions. Before, prayer came drop by drop; now they pour it out, it comes now like water from a fountain. Afflictions bring us to secret prayer. Consider Christ as the Speaker addressing his church. His resurrection from the dead was an earnest of all the deliverance foretold. The power of his grace, like the dew or rain, which causes the herbs that seem dead to revive, would raise his church from the lowest state. But we may refer to the resurrection of the dead, especially of those united to Christ.
