Eusebius of Caesarea

As this psalm is addressed to Solomon, the first verse of the psalm must be referred to him, and all the rest to the son of Solomon, not Rehoboam, who was king of Israel after him, but him that was of his seed according to the flesh, the Christ of God; for all who are acquainted with the holy Scriptures will agree that it is impossible to connect what is said in this psalm with Solomon or his successors, because of what they reveal about Christ. No, how is it possible to apply to Solomon, or his son Rehoboam, the burden of the whole psalm?—for instance, "He shall rule from sea to sea, and from the river to the ends of the earth." And "He shall remain as long as the sun, and before the moon for ever," and other similar statements. Yet the words at the beginning of the psalm are at once seen to apply to Solomon, which say, "O God, you will give judgment to the king," And the addition, "And your justice to the king's son," to the Son of Solomon, not his first-born who succeeded him in the kingdom (for he only ruled the Jewish nation seventeen years, being a wicked king), nor any of the successors of Rehoboam, but only to one of the seed of David, who could thus be called the son both of David and Solomon. And this is our Lord and Savior Jesus Christ. For his kingdom and its throne will stand as long as the sun. And he alone of people, as the Word of God, existed before the moon and the creation of the world, and he alone came down like dew from heaven on all the earth; and it was said in our quotation a little above, that he had risen on all people and that his justice would remain even until the consummation of life, which is called the removal of the moon. And our Savior's power is supreme from the eastern sea to the west, beginning its activity at the river, which is either the sacrament of baptism, or from Jordan, where he first appeared to benefit humankind. From that time his kingdom has spread and extended through the whole world.
