4 "Pay attention, my people. Listen to me, nations. Revelation flows from me. My decisions light up the world. 5 My deliverance arrives on the run, my salvation right on time. I'll bring justice to the peoples. Even faraway islands will look to me and take hope in my saving power. 6 Look up at the skies, ponder the earth under your feet. The skies will fade out like smoke, the earth will wear out like work pants, and the people will die off like flies. But my salvation will last forever, my setting-things-right will never be obsolete. 7 "Listen now, you who know right from wrong, you who hold my teaching inside you: Pay no attention to insults, and when mocked don't let it get you down. 8 Those insults and mockeries are moth-eaten, from brains that are termite-ridden, But my setting-things-right lasts, my salvation goes on and on and on."

9 Wake up, wake up, flex your muscles, God! Wake up as in the old days, in the long ago. Didn't you once make mincemeat of Rahab, dispatch the old chaos-dragon? 10 And didn't you once dry up the sea, the powerful waters of the deep, And then made the bottom of the ocean a road for the redeemed to walk across? 11 In the same way God's ransomed will come back, come back to Zion cheering, shouting, Joy eternal wreathing their heads, exuberant ecstasies transporting them - and not a sign of moans or groans. What Are You Afraid of - or Who? 12 "I, I'm the One comforting you. What are you afraid of - or who? Some man or woman who'll soon be dead? Some poor wretch destined for dust? 13 You've forgotten me, God, who made you, who unfurled the skies, who founded the earth. And here you are, quaking like an aspen before the tantrums of a tyrant who thinks he can kick down the world. But what will come of the tantrums? 14 The victims will be released before you know it. They're not going to die. They're not even going to go hungry.

Matthew Henry's Commentary on Isaiah 51:4-14

Commentary on Isaiah 51:4-8

(Read Isaiah 51:4-8)

The gospel of Christ shall be preached and published. How shall we escape if we neglect it? There is no salvation without righteousness. The soul shall, as to this world, vanish like smoke, and the body be thrown by like a worn-out garment. But those whose happiness is in Christ's righteousness and salvation, will have the comfort of it when time and days shall be no more. Clouds darken the sun, but do not stop its course. The believer will enjoy his portion, while revilers of Christ are in darkness

Commentary on Isaiah 51:9-16

(Read Isaiah 51:9-16)

The people whom Christ has redeemed with his blood, as well as by his power, will obtain joyful deliverance from every enemy. He that designs such joy for us at last, will he not work such deliverance in the mean time, as our cases require? In this world of changes, it is a short step from joy to sorrow, but in that world, sorrow shall never come in view. They prayed for the display of God's power; he answers them with consolations of his grace. Did we dread to sin against God, we should not fear the frowns of men. Happy is the man that fears God always. And Christ's church shall enjoy security by the power and providence of the Almighty.
