(5) Mine arms shall judge the people.--Literally, the peoples, including Israel and the heathen. The work of judgment thus, as ever, comes first; after it the isles (i.e., far-off countries), as representing the heathen, shall be converted, and trust the very Arm that smote them.

Verse 5. - My righteousness is near; my salvation is gone forth. "One day is with the Lord as a thousand years, and. a thousand years as one day" (2 Peter 3:8). Isaiah always speaks as if the Messianic kingdom was to supervene almost immediately on the return of the exiles to Palestine. It was not revealed to him that there would be an interval of from five hundred to six hundred years between the two events. By God's "righteousness" here we must understand his righteous plans for the redemption of his people through Christ, and for the punishment of those who resist his will and remain impenitent. The salvation and the judgment are the two parts of the "righteousness." The isles shall wait upon me (comp. Isaiah 41:1, 5; Isaiah 42:4, 10, 12; Isaiah 49:1; Isaiah 60:9, etc.; and the comment on Isaiah 42:4). On mine arm shall they trust. God's "arm" is his executive power - that might by which he effects his purposes. The "isles" or "countries" that have been expecting the coming of a Deliverer will have faith in his power to redeem and save them. Christianity was received with more readiness by the Gentiles than by the "peculiar people" (Acts 11:21; Acts 13:42, 46; Acts 14:1, 2; Acts 17:4, 5; Acts 18:6, etc.).

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 darknessMy righteousness is near,.... These are either the words of God the Father, and to be understood not of his essential righteousness, nor of his vindictive justice; but of the righteousness of his Son, which he calls his own, because he approves and accepts of it, imputes and reckons it to his people, and with it justifies them. The words may be rendered, "my righteous One", as in the Vulgate Latin version; not Cyrus, as Grotius; but Christ, God's righteous servant, who was near to come in the flesh, in order to work righteousness. Or these are the words of Christ, speaking of his own righteousness, which was near being wrought out by him, as it was when he became the end of the law for it, by obeying its precept, and bearing its penalty; and near being revealed in the Gospel, where it is revealed from faith to faith; and near being applied by the blessed Spirit, as it is to all that believe; and is near to be come at, and laid hold on, by faith:

my salvation is gone forth: the "salvation" appointed by the Lord; provided in covenant; wrought out by Christ; applied by the Spirit; and fully enjoyed in heaven: this is "gone forth" in the purpose and decree of God, in prophecy and promise, and in the declaration of the Gospel: or, "my Saviour", as the Vulgate Latin version; the Saviour of God's appointing, providing, and sending. Or these are the words of the Saviour himself, who has wrought it out, in whom it is, and of whom it is to be had; it is done, and ready for sinners to look unto and embrace; it is ready to be revealed, and to be fully enjoyed:

and mine arms shall judge the people; to whom the arm of the Lord is revealed, and the Gospel is the power of God unto salvation; both the arms of Christ are ready to receive them, and these protect and defend them, and judge, condemn, and destroy those that despise it:

the isles shall wait upon me; upon Christ, for his coming; for his salvation and righteousness; for his Gospel, the truths, promises, and blessings of it; and in his house and ordinances, for his presence. This is a prophecy of the conversion of the Gentiles, even in the isles of the sea, those afar off, as ours of Great Britain and Ireland, in which there have been and are many waiting upon him:

and on mine arm shall they trust; as on Christ, the arm of the Lord, for salvation; so on the power of Christ for protection and preservation; and on his promises in the Gospel, for their support; which is the arm of the Lord revealed unto them, and yields much support and comfort, and makes known that which is a proper object of trust.
