And all kings shall prostrate themselves before him. This verse contains a more distinct statement of the truth, That the whole world will be brought in subjection to the authority of Christ. The kingdom of Judah was unquestionably never more flourishing than under the reign of Solomon; but even then there were only a small number of kings who paid tribute to him, and what they paid was inconsiderable in amount; and, moreover, it was paid upon condition that they should be allowed to live in the enjoyment of liberty under their own laws. While David then began with his own son, and the posterity of his son, he rose by the Spirit of prophecy to the spiritual kingdom of Christ; a point worthy of our special notice, since it teaches us that we have not been called to the hope of everlasting salvation by chance, but because our heavenly Father had already destined to give us to his Son. From this we also learn, that in the Church and flock of Christ there is a place for kings; whom David does not here disarm of their sword nor despoil of their crown, in order to admit them into the Church, but rather declares that they will come with all the dignity of their station to prostrate themselves at the feet of Christ.
Yea, all kings shall fall down - That is, his reign will be universal. The kings and people mentioned in the previous verses are only specimens of what will occur. "All" kings - "all" nations - will do what these are represented as doing. They will submit to the Messiah; they will own him as their Lord. See the notes at Psalm 2:8. Compare Isaiah 49:23.
All kings shall fall down before - They shall reverence him on account of his great wisdom, riches, etc.
All nations shalt serve him - All the surrounding nations. This and the preceding verses are fully explained by 1-Kings 10:23-25 : "King Solomon exceeded all the kings of the earth for riches and for wisdom. And all the earth sought unto Solomon to hear his wisdom. And they brought every man his present, vessels of silver, and vessels of gold, and garments and armor, and spices, horses and mules a rate year by year." If we take these expressions to mean literally all the habitable globe, then they cannot be applied to Solomon; but if we take them as they are most evidently used by the sacred writer, then they are literally true. When all the earth shall be brought to receive the Gospel of Christ, then they may be applied to him.
Yea, all kings shall fall down before him,.... Or worship him; not with a civil, but religious worship; for such worship is due to Christ, he being God equal with the Father, and so to be equally honoured; the Creator of all things, the Redeemer of his people, Head and Lord of the church, and whom the angels adore; every part of worship is to be given him; internal, which lies in the exercise of faith, hope, love, fear, &c. and external, which consists of prayer to him, praise of him, preaching in his name, and the administration of ordinances; and this worship is to be performed in the same manner as to the Father, in spirit and in truth, in righteousness and holiness, with reverence and godly fear. This is to be understood, either literally of the kings of the earth, and which will have its full accomplishment in the latter day; see Isaiah 49:23; or mystically of such who are made kings unto God the Father by Christ; who reign spiritually now, through the power of divine grace in their hearts; have the honour, riches, and attendance of kings, and a crown and kingdom prepared for them; and shall reign with Christ on earth, though under him, at whose feet they cast their crowns: all this shows the dignity of Christ's person and office; that he is the Prince of the kings of the earth, the firstborn of God, whom he has made higher than they, and King of kings, and Lord of lords; whose princes, and all whose subjects, are altogether kings. This passage is allowed to belong to the Messiah, both by ancient and modern Jews (g); and indeed it never was true of Solomon, nor of any other;
all nations shall serve him; which will be in the latter day; see Isaiah 2:2; the Jews say (h), that in the world to come, or the times of the Messiah, all the Gentiles shall be voluntary proselytes.
