9 Awake, awake, put on strength, arm of Yahweh; awake, as in the days of old, the generations of ancient times. Isn’t it you who cut Rahab in pieces, who pierced the monster? 10 Isn’t it 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 pass over? 11 The ransomed of Yahweh shall return, and come with singing to Zion; and everlasting joy shall be on their heads: they shall obtain gladness and joy; and sorrow and sighing shall flee away. 12 “I, even I, am he who comforts you: who are you, that you are afraid of man who shall die, and of the son of man who shall be made as grass; 13 and have forgotten Yahweh your Maker, who stretched forth the heavens, and laid the foundations of the earth; and fear continually all the day because of the fury of the oppressor, when he makes ready to destroy? and where is the fury of the oppressor? 14 The captive exile shall speedily be freed; and he shall not die and go down into the pit, neither shall his bread fail. 15 For I am Yahweh your God, who stirs up the sea, so that its waves roar: Yahweh of Armies is his name. 16 I have put my words in your mouth, and have covered you in the shadow of my hand, that I may plant the heavens, and lay the foundations of the earth, and tell 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.
