4 Attend unto me, O my people; and give ear unto me, O my nation: for a law shall go forth from me, and I will establish my justice for a light of the peoples. 5 My righteousness is near, my salvation is gone forth, and mine arms shall judge the peoples; the isles shall wait for me, and on mine arm shall they trust. 6 Lift up your eyes to the heavens, and look upon the earth beneath; for the heavens shall vanish away like smoke, and the earth shall wax old like a garment; and they that dwell therein shall die in like manner: but my salvation shall be for ever, and my righteousness shall not be abolished. 7 Hearken unto me, ye that know righteousness, the people in whose heart is my law; fear ye not the reproach of men, neither be ye dismayed at their revilings. 8 For the moth shall eat them up like a garment, and the worm shall eat them like wool; but my righteousness shall be for ever, and my salvation unto all generations.
9 Awake, awake, put on strength, O arm of Jehovah; awake, as in the days of old, the generations of ancient times. Is it not thou that didst cut Rahab in pieces, that didst pierce the monster? 10 Is it not thou that driedst up the sea, the waters of the great deep; that madest the depths of the sea a way for the redeemed to pass over? 11 And the ransomed of Jehovah shall return, and come with singing unto Zion; and everlasting joy shall be upon their heads: they shall obtain gladness and joy; [and] sorrow and sighing shall flee away. 12 I, even I, am he that comforteth you: who art thou, that thou art afraid of man that shall die, and of the son of man that shall be made as grass; 13 and hast forgotten Jehovah thy Maker, that stretched forth the heavens, and laid the foundations of the earth; and fearest continually all the day because of the fury of the oppressor, when he maketh ready to destroy? and where is the fury of the oppressor? 14 The captive exile shall speedily be loosed; and he shall not die [and go down] into the pit, neither shall his bread fail.
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.
