He shall judge the poor of the people - The afflicted; the down-trodden; the needy. He would vindicate their cause against their oppressors; his reign would be one of impartial justice, under which the rights of the poor as well as of the rich would be respected. See the notes at Isaiah 11:4.

He shall save the children of the needy - Those in humble life; those most likely to be oppressed by others; those who have no natural protectors.

And shall break in pieces the oppressor - Shall subdue, or destroy, those who live to oppress others. See the notes at Psalm 12:5.

He shall judge the poor of the people,.... Of the people of God, whether among Jews or Gentiles; See Gill on Psalm 72:2;

he shall save the children of the needy; whose parents being needy, they are so too, in a spiritual sense, and in distressed circumstances. Such Christ saves from their sins; from the curses and condemnation of the law: from, wrath to come, and out of the hands of all their enemies;

and shall break in pieces the oppressor; the tyrant Satan, the god of this world; that has usurped a power over it; who works in the children of disobedience, and leads captive the people of God in their unregenerate state: the "calumniator", as some render the word; the accuser of the brethren: "the defrauder" (q), as others: who beguiled our first parents, and deceives mankind. Now it was foretold of Christ that he should break his head; and he was manifested in the flesh to destroy his works; and him himself; and he has broke him and all his schemes in pieces, and spoiled all his principalities and powers: The Syriac Version reads, "tyrants" or "oppressors", in the plural number; and it may include the Jews, who were the persecutors and oppressors of the first Christians; and Rome, Pagan and Papal; antichrist, and all the antichristian states, which have been, or will be, broken to pieces by Christ; who will rule them with a rod of iron, and break them in pieces as a potter's vessel, Revelation 2:27.

(q) "calumniatorem", Pagninus, Tigurine version, Vatablus, Musculus; "fraudatorem", Muis, Cocceius.

He shall {e} judge the poor of the people, he shall save the children of the needy, and shall break in pieces the oppressor.

(e) He shows why the sword is committed to Kings that is, to defend the innocent, and suppress the wicked.

72:4 Judge - Vindicate them from their oppressors.

4. That peace, including prosperity, as an eminent characteristic of Christ's reign (Isa 2:4; Isa 9:6; 11:9), will be illustrated in the security provided for the helpless and needy, and the punishment inflicted on oppressors, whose power to injure or mar the peace of others will be destroyed (compare Isa 65:25; Zec 9:10).

children of the needy-for the needy (compare sons of strangers, Ps 18:45 [Margin]).

72:2-17 This is a prophecy of the kingdom of Christ; many passages in it cannot be applied to the reign of Solomon. There were righteousness and peace at first in the administration of his government; but, before the end of his reign, there were troubles and unrighteousness. The kingdom here spoken of is to last as long as the sun, but Solomon's was soon at an end. Even the Jewish expositors understood it of the kingdom of the Messiah. Observe many great and precious promises here made, which were to have full accomplishment only in the kingdom of Christ. As far as his kingdom is set up, discord and contentions cease, in families, churches, and nations. The law of Christ, written in the heart, disposes men to be honest and just, and to render to all their due; it likewise disposes men to live in love, and so produces abundance of peace. Holiness and love shall be lasting in Christ's kingdom. Through all the changes of the world, and all the changes of life, Christ's kingdom will support itself. And he shall, by the graces and comforts of his Spirit, come down like rain upon the mown grass; not on that cut down, but that which is left growing, that it may spring again. His gospel has been, or shall be, preached to all nations. Though he needs not the services of any, yet he must be served with the best. Those that have the wealth of this world, must serve Christ with it, do good with it. Prayer shall be made through him, or for his sake; whatever we ask of the Father, should be in his name. Praises shall be offered to him: we are under the highest obligations to him. Christ only shall be feared throughout all generations. To the end of time, and to eternity, his name shall be praised. All nations shall call HIM blessed.
