9 Awake, awake, put on strength, O arm of Jehovah; awake, as in the days of old, [as in] the generations of passed ages. Is it not thou that hath hewn Rahab in pieces, [and] pierced the monster? 10 Is it not thou that dried up the sea, the waters of the great deep; that made the depths of the sea a way for the redeemed to pass over? 11 So the ransomed of Jehovah shall return, and come to Zion with singing; and everlasting joy shall be upon their heads: they shall obtain gladness and joy; sorrow and sighing shall flee away. 12 I, [even] I, am he that comforteth you: who art thou, that thou fearest a man that shall die, and the son of man that shall become as grass; 13 and forgettest Jehovah thy Maker, who hath stretched out the heavens, and laid the foundations of the earth; and thou art afraid continually all the day because of the fury of the oppressor, when he prepareth to destroy? And where is the fury of the oppressor? 14 He that is bowed down shall speedily be loosed, and he shall not die in the pit, nor shall his bread fail. 15 And I am Jehovah thy God, who raiseth the sea, so that its waves roar: Jehovah of hosts is his name. 16 And I have put my words in thy mouth, and covered thee with the shadow of my hand, to plant the heavens, and to lay the foundations of the earth, and to say unto Zion, Thou art 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.
