“Further, to persuade you that you have not understood anything of the Scriptures, I will remind you of another psalm, dictated to David by the Holy Spirit, which you say refers to Solomon, who was also your king. But it refers also to our Christ. But you deceive yourselves by the ambiguous forms of speech. For where it is said, 'The law of the Lord is perfect,' you do not understand it of the law which was to be after Moses, but of the law which was given by Moses, although God declared that He would establish a new law and a new covenant. And where it has been said, 'O God, give Thy judgment to the king,' since Solomon was king, you say that the Psalm refers to him, although the words of the Psalm expressly proclaim that reference is made to the everlasting King, i.e., to Christ. For Christ is King, and Priest, and God, and Lord, and angel, and man, and captain, and stone, and a Son born, and first made subject to suffering, then returning to heaven, and again coming with glory, and He is preached as having the everlasting kingdom: so I prove from all the Scriptures.”

“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.”

“Concerning Solomon He prayed this prayer on behalf of his son Solomon, for he foresaw with the holy spirit that he [Solomon] was destined to request of the Holy One, blessed be He, “a heart to understand, to hear judgment.” Your judgments the wisdom of Your laws, which You commanded in the Torah. and Your righteousness to judge justly. to a king, etc., to a king’s son Both refer to Solomon. Another explanation: Give Your judgments to a king The chastisements should end with me, and the charity You should bestow upon my son; viz. that there be peace in his days.”

“Give the King thy judgments, O God,.... A prayer of David, or of the church he represents, to God the Father concerning Christ; for he is "the King" meant; which is the sense of the old Jewish synagogue: the Targum is, "give the constitutions of thy judgments to the King Messiah;'' and so their Midrash (m) interprets it. He is "the King", by way of eminence, as in Psa 45:1; not only the King of the world in right of creation and preservation, in conjunction; with his Father, having an equal right with him; but of saints, of the church and people of God, by the designation and constitution of his Father; hence he was promised and prophesied of as a King, Jer 23:5, Zac 9:9; and he came into the world as such, though his kingdom did not appear very manifest in his state of humiliation; yet at his ascension it did, when he was made and declared Lord and Christ; and it is for the manifestation of his kingdom, and the glory of it, the psalmist here prays. For by "judgments" are meant not the statutes and laws of God, given him to be shown, explained unto, and enforced on others, which rather belongs to his prophetic office, or as the rule of his government; nor the judgments of God to be inflicted upon wicked men, which is only one part of his kingly office; but of all power in heaven and in earth, which was given him by his Father upon his resurrection, and about the time of his ascension, Mat 28:18; and is the same with "all judgment" committed by him to his Son, Joh 5:22; and which explains the clause here, and is the reason why it is expressed in the plural number here; which takes in the whole of the power and authority, the kingdom, and the greatness of the kingdom, delivered to Christ; and which chiefly lies in the government of the church, which is on his shoulders, and is committed into his hand; exercised in enacting laws, and delivering out ordinances, to be observed by the saints, and in the protection and defence of them; and also includes his judgment of the world at the last day, to which he is ordained and appointed by his Father, and will be managed and conducted by him; and thy righteousness unto the King's Son; who is the same with the King, as Jarchi well observes; for only one single person is afterwards spoken of, and designs the Messiah; who, as a divine Person, is the Son of the King of kings, the only begotten of the Father, the true and proper Son of God; and, as man, the Son of David the king. And so the Targum, "and thy righteousness to the Son of David the king;'' a known name of the Messiah, Mat 1:1. And by "righteousness" is meant, not the essential righteousness of God; this Christ has by nature equally with his divine Father, and is not given or communicated to him; but the fulness of the graces of the Spirit, and perfection of virtues, which he received without measure; whereby, as Mediator, he is abundantly qualified to judge with righteousness, and reprove with equity; and not as other judges do, after the sight of the eyes, or hearing of the ears; see Isa 11:2. Unless it can be understood of the everlasting righteousness, which Christ has wrought out, called his Father's, because appointed in council and covenant, approved of and accepted by him, and imputed to his people. To work out this righteousness was not only given to Christ in covenant, but he was sent in the fulness of time to do it; and had a power given him, as Mediator, to justify many with it, Isa 53:11; and which may be here prayed for. Jerom, by the "King's Son", understands such as are regenerated, and taken into the adoption of children; and to such the righteousness of God is given. This is a truth, but not the sense of the text. (m) In Yalkut Simeoni, par. 2. fol. 112. 2.”

“Psalm. Some copies add, “of David.” But the Hebrew has only Lishlomo, “to Solomon;” (St. Jerome; Haydock) or, composed by Solomon. The former sense is more generally adopted, (Berthier) though the Chaldean and Eusebius look upon the latter as most plausible. David, however, seems to have written this last most beautiful piece, when he placed his son upon the throne; (3 Kings i. 47.) and being transported with a divine enthusiasm, he described the reign of the Messias, (Calmet) to whom alone many of the passages can be applied, (St. Augustine; Worthington) as the Jews, Chaldean, Kimchi, &c., confess, though they will not allow Jesus to be the Christ, ver. 5, 11, 17.

“The name of God, occurring only once, is Elohim; and this is sufficient to stamp the Psalm as an Elohimic Psalm. מלך (cf. Psa 21:2) and בּן־מלך are only used without the article according to a poetical usage of the language. The petition itself, and even the position of the words, show that the king's son is present, and that he is king; God is implored to bestow upon him His משׁפּטים, i.e., the rights or legal powers belonging to Him, the God of Israel, and צדקה, i.e., the official gift in order that he may exercise those rights in accordance with divine righteousness. After the supplicatory teen the futures which now follow, without the Waw apodoseos, are manifestly optatives. Mountains and hills describe synecdochically the whole land of which they are the high points visible afar off. נשׂא is used in the sense of נשׂא פּרי Eze 17:8 : may שׁלום be the fruit which ripens upon every mountain and hill; universal prosperity satisfied and contented within itself. The predicate for Psa 72:3 is to be taken from Psa 72:3, just as, on the other hand, בּצדקה, "in or by righteousness," the fruit of which is indeed peace (Isa 32:17), belongs also to Psa 72:3; so that consequently both members supplement one another. The wish of the poet is this: By righteousness, may there in due season be such peaceful fruit adorning all the heights of the land. Psa 72:3, however, always makes one feel as though a verb were wanting, like תּפרחנה suggested by Bttcher. In Psa 72:4 the wishes are continued in plain unfigurative language. הושׁיע in the signification to save, to obtain salvation for, has, as is frequently the case, a dative of the object. בּני־אביון are those who are born to poverty, just like בּן־מלך, one who is born a king. Those who are born to poverty are more or less regarded, by an unrighteous government, as having no rights.”
