Isaiah 51:4

But the great work of the future extends far beyond the restoration of Israel, which becomes the source of salvation to all the world. "Hearken unto me, my people, and give ear unto me, O my congregation! for instruction will go forth from me, and I make a place for my right, to be a light of the nations. My righteousness is near, my salvation is drawn out, and my arms will judge nations: the hoping of the islands looks to me, and for mine arm is their waiting." It is Israel which is here summoned to hearken to the promise introduced with kı̄. לאוּמּי is only used here of Israel, like גּוי in Zep 2:9; and the lxx (καὶ οἱ βασιλεῖς) have quite misunderstood it. An address to the heathen would be quite out of harmony with the character of the whole prophecy, which is carried out quite consistently throughout. עמי and לאומי, therefore, are not plurals, as the Syriac supposes, although it cannot be disputed that it is a rare thing to meet with the plural form apocopated thus, after the form of the talmudic Aramaean; and see also at Psa 45:9). What Isa 42:1. describes as the calling of the servant of Jehovah, viz., to carry out justice among the nations, and to plant it on the earth, appears here as the act of Jehovah; but, as a comparison of מאתּי with מצּיּון (Isa 2:3) clearly shows, as the act of the God who is present in Israel, and works from Israel outwards. Out of Israel sprang the Saviour; out of Israel the apostleship; and when God shall have mercy upon Israel again, it will become to the whole world of nations "life from the dead." The thorâh referred to here is that of Sion, as distinguished from that of Sinai, the gospel of redemption, and mishpât the new order of life in which Israel and the nations are united. Jehovah makes for this a place of rest, a firm…

Both these proclamations, as I may call them, end alike with an assurance of the perpetuity of God's righteousness and his salvation; and therefore we put them together, both being designed for the comfort of God's people. Observe, I. Who they are to whom this comfort belongs: "My people, and my nation, that I have set apart for myself, that own me and are owned by me." Those are God's people and his nation who are subject to him as their King and their God, pay allegiance to him, and put themselves under his protection accordingly. They are a people who know righteousness, who not only have the means of knowledge, and to whom righteousness is made known, but who improve those means, and are able to form a right judgment of truth and falsehood, good and evil. And, as they have good heads, so they have good hearts, for they have the law of God in them, written and ruling there. Those God owns for his people in whose hearts his law is. Even those who know righteousness, and have the law of God in their hearts, may yet be in great distress and sorrow, and loaded with reproach and contempt; but their God will comfort them with the righteousness they know and the law they have in their hearts. II. What the comfort is that belongs to God's people. 1. That the gospel of Christ shall be preached and published to the world: A law shall proceed from me, an evangelical law, the law of Christ, the law of faith, Isa 2:3. This law is his judgment; for it is that law of liberty by which the world shall be governed and judged. This shall not only go forth, but shall continue and rest, it shall take firm footing and deep root in the world. It shall rest, not only for the benefit of the Jews, who had the first notice of it, but for a light of the people of other nations. It is this law,…

51:4 my law . . . my justice: The work of the servant will prosper because justice will be the rule in God’s kingdom on earth (see 42:1-4). • a light to the nations: The nations will receive the Lord and his revelation (see also 42:6; 49:6; 60:1-3; 66:19-23; Matt 4:15-16; Luke 2:32; John 1:4-9; 12:35-50; Acts 13:47).
