9 Awake , awake , put on strength , O arm of the Lord ; Awake as in the days of old , the generations of long ago . Was it not You who cut Rahab in pieces , Who pierced the dragon ? 10 Was it not You who dried up the sea , The waters of the great deep ; Who made the depths of the sea a pathway For the redeemed to cross over ? 11 So the ransomed of the Lord will return And come with joyful shouting to Zion , And everlasting joy will be on their heads . They will obtain gladness and joy , And sorrow and sighing will flee away. 12 "I, even I, am He who comforts you. Who are you that you are afraid of man who dies And of the son of man who is made like grass , 13 That you have forgotten the Lord your Maker , Who stretched out the heavens And laid the foundations of the earth , That you fear continually all day long because e of the fury of the oppressor , As he makes ready to destroy ? But where is the fury of the oppressor ? 14 "The exile will soon be set free , and will not die in the dungeon , nor will his bread be lacking . 15 "For I am the Lord your God , who stirs up the sea and its waves roar (the Lord of hosts is His name ). 16 "I have put My words in your mouth and have covered you with the shadow of My hand , to establish the heavens , to found the earth , and to say to Zion , 'You are My people .' "

Matthew Henry's Commentary on Isaiah 51:9-16

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.
