9 Awake, awake, put on strength, O arm of the Lord! Awake, as in 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 way for the redeemed to cross over? 11 So the ransomed of the Lord shall return, and come to Zion with singing; everlasting joy shall be upon their heads; they shall obtain joy and gladness, and sorrow and sighing shall flee away. 12 I, I am he who comforts you; why then are you afraid of a mere mortal who must die, a human being who fades like grass? 13 You have forgotten the Lord, your Maker, who stretched out the heavens and laid the foundations of the earth. You fear continually all day long because of the fury of the oppressor, who is bent on destruction. But where is the fury of the oppressor? 14 The oppressed shall speedily be released; they shall not die and go down to the Pit, nor shall they lack bread. 15 For I am the Lord your God, who stirs up the sea so that its waves roar- the Lord of hosts is his name. 16 I have put my words in your mouth, and hidden you in the shadow of my hand, stretching out the heavens and laying the foundations of the earth, and saying 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.
