“And as they kept silence, I went on: "[The Scripture], speaking by David about this Christ, my friends, said no longer that `in His seed' the nations should be blessed, but `in Him.' So it is here: `His name shall rise up for ever above the sun; and in Him shall all nations be blessed.' But if all nations are blessed in Christ, and we of all nations believe in Him, then He is indeed the Christ, and we are those blessed by Him. God formerly gave the sun as an object of worship, as it is written, but no one ever was seen to endure death on account of his faith in the sun; but for the name of Jesus you may see men of every nation who have endured and do endure all sufferings, rather than deny Him. For the word of His truth and wisdom is more ardent and more light-giving than the rays of the sun, and sinks down into the depths of heart and mind. Hence also the Scripture said, `His name shall rise up above the sun.' And again, Zechariah says, `His name is the East.' And speaking of the same, he says that `each tribe shall mourn.'"”

“But he who is before the heavens, which, according to you, are also before time, is at the same time before the ages. He is not only before the ages but before all generations that have ever existed. Why do you limit divine and infinite things by those that are perishable, earthly and narrow? Paul knows nothing in Christ except the eternity of the ages. Wisdom states that It is not after something but before all things. In your opinion, the periods of time have been determined from the sun and the moon. But David points out that Christ remains before the sun when he says, "Before the sun [is] his name." And in order that you may not conclude that the things of God had their beginning with the origin of the world, the same one said, "And before the moon [are] the generations of generations." Periods of time are here regarded as of no importance by such outstanding men who were worthy of the Spirit of prophecy, and the human mind has not been afforded any opportunity for reaching into the ages before the birth that transcends the eternal years. Let the faith remain within the limits of the God-fearing teaching, so that the Lord Jesus Christ is the only-begotten God and that he has been born in order that we may confess the perfect birth, and let it not forget that he is eternal when venerating his divinity.”

“And if, as David says in the seventy-first [LXX] psalm, "His name remains before the sun and before the moon, from one generation to another," how did he receive what he always had, even before he now received it? Or how is he exalted, being before his exaltation the Most High? Or how did he receive the right of being worshiped, who before he now received it, was always worshiped? It is not an obscure saying but a divine mystery. "In the beginning was the Word, and the Word was with God, and the Word was God"; but for our sakes afterwards the "Word was made flesh." And the term in question, "highly exalted," does not signify that the essence of the Word was exalted, for he always existed and is "equal to God," but the exaltation is of the human nature.”

“"Be," therefore, "the name of Him blessed for ever: before the sun endures the name of Him" [Psalm 72:17]. By the sun times are signified. Therefore for everlasting endures the name of Him. For eternity does precede times, and is not bounded by time. "And there shall be blessed in Him all the tribes of the earth." For in Him is fulfilled that which has been promised to Abraham. "For He says not, In seeds, as though in many; but as though in one, And to your Seed, which is Christ." [Galatians 3:16] But to Abraham is said, "In your Seed shall be blessed all the tribes of the earth." [Genesis 22:18] And not the sons of the flesh but the sons of promise are counted in the Seed. [Romans 9:8] "All nations shall magnify Him." As if in explanation there is repeated that which above has been said. For because they shall be blessed in Him, they shall magnify Him; not of themselves making Him to be great, that of Himself is great, but by praising and confessing Him to be great. For thus we magnify God: thus also we say, "Hallowed be Your name," [Matthew 6:9] which is indeed always holy.”

“His name shall endure for ever,.... As a King; for he is chiefly spoken of here in his kingly office: not merely the fame of him; for so the fame of an earthly king; even of a tyrant, may continue as long as the world does; but the meaning is, that he himself should continue in his office for ever: his throne is for ever and ever; of his government there will be no end; his kingdom is an everlasting one; he shall reign over the house of Jacob, and on the throne of David, for ever and ever: he shall have no successor in this his office, any more than in the priestly office; which is an unchangeable one, or does not pass from one to another: his Gospel is his name, Act 9:15; and that shall endure for ever, or to the end of the world; until all his elect are gathered in, notwithstanding the violent persecutions of men, the cunning craft of false teachers, and the death of Gospel ministers and professors: as long as this is preached, Christ's name will endure, since he is the sum and substance of it; and not only is his name perpetuated in his Gospel, but also in his ordinances, those of baptism and the Lord's supper, which are administered in his name, and will be unto his second coming; his name shall be continued as long as the sun; or "shall be sonned" or "filiated" (r); that is, shall be continued in his sons, in his spiritual offspring, as long as the sun lasts; as the names of parents are continued in their children; so the name of Christ is, and will be, continued in him: he has children which the Lord has given him; a seed that he shall see in all periods of time, to whom he stands in the relation of the everlasting Father; these bear his name, are called "Christians" from him, and these his seed and offspring shall endure for ever: for though sometimes their number may be few; yet there are always some in the worst of times; Christ has always had some to bear his name, and ever will have; and in the latter day they will be very numerous, even as the sand of the sea. The Jews take the word "Yinnon", here used, for a name of the Messiah (s), and render the words, "before the sun his name was Yinnon"; and so the Targum, "before the sun was, or was created, (as in the king's Bible,) his name was prepared;'' or appointed: for they say (t), the name of the Messiah was one of the seven things created before the world was: it is certain that Christ was the Son of God, from eternity, or the eternal Son of God: he was so before his resurrection from the dead, when he was only declared, and did not then become the Son of God: he was owned by his divine Father, and believed in as the Son of God by men before that time: he was so before his incarnation, and not by that: he, the Son of God, was sent in human nature, and made manifest in it, and was known by David and Solomon, under that relation; and, as such, he was concerned in the creation of all things; and was in the day of eternity, and from all eternity, the only begotten Son of the Father; see Psa 2:7; but the version and sense which Gussetius (u) gives seem best of all; "his name shall generate", or "beget children before the sun"; that is, his name preached, as the Gospel, which is his name, Act 9:15, shall be the means of begetting many sons and daughters openly and publicly, in the face of the sun, and wherever that is; and men shall be blessed in him; men, and not angels, sinful men; such as are by nature children of wrath, and cursed by the law of works, yet blessed in Christ; even all elect men, all that are chosen in him, whether Jews or Gentiles; for he is the "seed of Abraham", in whom "all the nations of the earth should be blessed", Gen 22:18; as they are with all spiritual blessings; with redemption, peace, pardon, righteousness, and eternal life: they are in him, and blessed in him; he is their head and representative, and so blessed in him; he is the fountain, cause, author, and giver of all blessings; they all come from him, through him, and for his sake, through his blood, righteousness, and sacrifice. Or, "they shall be blessed in him": that is, his children and spiritual offspring, in whom his name is perpetuated. Or, "they shall bless themselves in him" (w); reckon themselves blessed in him, and make their boast of him, and glory in him; all nations shall call him blessed; as he is a divine Person; not only the Son of the Blessed, but God over all, blessed for ever; and as man, being set at the right hand of God, crowned with glory and honour, and all creatures, angels and men, subject to him; and as Mediator, acknowledging him to be the fountain of all blessedness to them, and, upon that account, ascribing all blessing, honour, glory, and praise, unto him.

“Continueth. Protestants marginal note, “shall be as a son, to continue his father’s name for ever.” The Messias is the eternal son of God. Hebrew yinnin, (Keri.) might be rendered (Haydock) filiabitur, (Montanus) if this word were Latin. The ancient Jews considered this as one of the titles of the Messias. Chaldean, “before the sun was, his name was prepared.” (Berthier) — This is the third time that the glory of Christ is pronounced eternal, ver. 5., and 7. (Haydock) — He is for ever blessed: but we cannot think of Solomon, without remembering his almost incredible fall. (Calmet) — Blessed. This was spoken only of the Messias, (Berthier) who is the cause of salvation to all the elect. None are saved who do not continue in Him, (Menochius) by faith and good works.”
