He hath set in order the people under us Some translate the verb he hath subjected; and this agrees with the translation which I have given. Others translate it he hath led, which is somewhat more remote from the meaning. But to understand the verb ydvr, yadebber, as meaning to destroy, as is done by others, is altogether at variance with the mind of the prophet; for it is doubtless an advantageous, joyful, and desirable subjection which is here meant. In the Hebrew, the verb is in the future tense, he will set in order; and if any are disposed to prefer retaining it in this tense, I have no great objection to it. As, however, it is certain that under the figure of the kingdom of David there is here celebrated the grace of God to come, I have readily adopted that rendering which has been preferred by other interpreters. Besides, although in this verse the prophet especially exhorts his own countrymen to gratitude to God, because, through his favor, they ruled over all people; yet it is certain that he means, that those also who were subdued are associated with the Jews in this joy. The body does not differ more from the shadow than the reigned expressions of joy with which the heathen nations honored David in old time, differ from those with which the faithful through the whole world receive Christ,; for the latter flow from the willing obedience of the heart. And assuredly, if after the ark was brought to the temple, there had not appeared hidden under this figure something far higher, which formed the substance of it:, it would have been as it were a childish joy to assign to God his dwelling there, and to shut him up within such narrow limits. But when the majesty of God which had dwelt in the tabernacle was manifested to the whole world, and when all nations were brought in subjection to his authority, this prerogative of the offspring of Abraham was then illustriously manifested. The prophet, then, when he declares that the Gentiles Will be subdued, so that they will not refuse to obey the chosen people, is describing that kingdom of which he had previously spoken. We are not to suppose that he here treats of that secret providence by which God governs the whole world, but of the special power which he exercises by means of his word; and, therefore, in order that he may be properly called a King, his own people must necessarily acknowledge him as such. It may, however, be asked, "Since Christ has brought the Church under his own authority and celestial power, in what sense can it be said that the nations are subject to the Jews, seeing we know that the order of the Church cannot be settled aright, and as it ought to be, unless Christ the only head stand forth prominently above all, and all the faithful, from the greatest to the least, keep themselves in the humble rank of members? Nay, more, when Christ erected his dominion through the whole world, the adoption, which had before been the peculiar privilege of one people, began to be the common privilege of all nations; and by this means liberty was granted to all together, that being united to one another by the ties of true brotherhood, they should aspire to the celestial inheritance." The answer to this is easy: When the yoke of the law, was imposed upon the Gentiles, the Jews then obtained the sovereignty over them; even as by the word the pastors of the Church exercise the jurisdiction of the Holy Spirit. For this very reason the Church is called a Queen, and the Mother of all the godly, (Galatians 4:26,) because divine truth, which is like a scepter to subdue us all, has been committed to her keeping. Although then the Jews, when the kingdom of Christ emerged into light, were in a state of wretched and ignominious servitude to heathen nations, and had been, as it were, their slaves; yet the sovereignty is truly and justly attributed to them, because God "sent the rod of his strength out of Zion," (Psalm 110:2;) and as they were intrusted with the keeping of the la their office was to restrain and subdue the Gentiles by its authority. The only way by which the rest of the world has been brought into subjection to God is, that men, being renewed by the Spirit of God, have willingly yielded themselves docile and tractable to the Jews, and suffered themselves to be under their dominion; as it is said in another passage, "In those days it shall come to pass, that ten men shall take hold out of all languages of the nations, even shall take hold of the skirt of him that is a Jew, saying, We will go with you;for we have heard that God is with you," (Zechariah 8:23.)

He shall subdue the people under us - Compare Psalm 18:39, note; Psalm 18:47, note. The word rendered "subdue" is that which commonly means" to speak." The idea in the use of this word here is that he has only to speak and it is done (compare Psalm 33:9), or that he could do it by a word. Compare, however, on the use of the word here, Gesenius (Lexicon), on the word - דבר dâbar, 2, Hiphil.
And the nations under our feet - That is, they shall be entirely or effectually subdued. See Psalm 7:5, note; Psalm 44:5, note. As God would enable them to do this, it was an occasion for thankfulness and triumph.

He shall subdue the people under us - He shall do again for us what he had done for our forefathers - give us dominion over our enemies, and establish us in our own land. I would rather read this in the past tense, relative to what God did for their fathers in destroying the Canaanites, and giving them the promised land for their possession, and taking the people for his own inheritance. This is also applied to the conversion of the Gentiles who, on the rejection of the Jews, have become his inheritance; and whom he has chosen to inherit all those spiritual blessings typified by the sacrifices and other significant rites and ceremonies of the Jewish Church.

He shall (b) subdue the people under us, and the nations under our feet.
(b) He has made the Jews who were the keepers of the law and prophets, schoolmasters to the Gentiles, that they would with gladness obey them.

He shall subdue the people under us, and the nations under our feet. As Joshua, his type, subdued the Canaanites; and as David, another type of subdued the Syrians, Moabites, and others: the Jews from these words expect, that, in the times of the Messiah they look for, the Gentiles in a literal sense will be subdued by him, and become subject to them; but these, and all other expressions of the like kind, are to be understood in a spiritual sense; such as Isaiah 49:23; and which will have their accomplishment in the latter day, in the subjection of the Gentiles to the word and ordinances of the Gospel administered in his churches: though the passage here refers to the times following the ascension of Christ to heaven, when he went forth in the ministry of his apostles conquering and to conquer; and which he made use of to cause the people to fall under him, and to be willing to be saved by him; to submit to his righteousness, and to his ordinances, the sceptre of his kingdom; and which was causing them to triumph, and subduing the people under them, who through the Gospel preached by them became obedient by word and deed; and which was an occasion of joy even to the conquered ones.

under us--that is, His saints; Israel's temporal victories were types of the spiritual conquests of the true Church.

Subdue - He speaks this in the name of the whole church, to which all particular believers were to submit themselves in the Lord.
