A psalm for David himself. Sing ye to the Lord anew canticle: because he hath done wonderful things. His right hand hath wrought for him salvation, and his arm is holy.

“Along with my prayers I now add book 10 to the Church History and dedicate it to you, my most consecrated Paulinus, and blazon you as the seal of the whole work. It is appropriate that in a perfect number I shall here provide a completed account in celebration of the restoration of the churches, in obedience to the divine Spirit who urges us: Sing to the Lord a new song, for he has done marvelous things; His right and his holy arm have wrought salvation for him. The Lord has made known his salvation: His righteousness he has revealed in the sight of the heathen. Accordingly, let me now sing the new song, since after those grim and horrifying scenes and narratives, I was now privileged to see and to celebrate what many righteous people and martyrs of God before me desired to see but did not see and to hear but did not hear. But they hurried on to far better things in the heavens, caught up into a paradise of divine bliss, while I, admitting that even the present circumstances are more than I deserve, have been totally astonished at the magnitude of grace he has conferred and offer him my total awe and worship, confirming the truth of the prophecies that declare: Come and behold the works of the Lord, What wonders he has wrought on the earth, Making wars to cease to the ends of the world. He will break the bow and shatter the spear, And the shields he will burn with fire. Rejoicing that all this has been clearly fulfilled, let me proceed with my narrative.”

“"O sing unto the Lord a new song" [Psalm 98:1]. The new man knows this, the old man knows it not. The old man is the old life, and the new man the new life: the old life is derived from Adam, the new life is formed in Christ. But in this Psalm, the whole world is enjoined to sing a new song. More openly elsewhere the words are these: "O sing unto the Lord a new song; sing unto the Lord, all the whole earth;" that they who cut themselves off from the communion of the whole earth, may understand that they cannot sing the new song, because it is sung in the whole, and not in a part of it. Attend here also, and see that this is said. And when the whole earth is enjoined to sing a new song, it is meant, that peace sings a new song. "For He has done marvelous things." What marvelous things? Behold, the Gospel was just now being read, and we heard the marvellous things of the Lord. The only son of his mother, who was a widow, was being carried out dead: the Lord, in compassion, made them stand still; they laid him down, and the Lord said, "Young man, I say unto you, Arise." [Luke 7:12-14] ..."The Lord has done marvellous things." What marvellous things? Hear: "His own right hand, and His holy arm, has healed for Him." What is the Lord's holy Arm? Our Lord Jesus Christ. Hear Isaiah: "Who has believed our report, and to whom is the arm of the Lord revealed?" [Isaiah 53:1] His holy arm then, and His own right hand, is Himself. Our Lord Jesus Christ is therefore the arm of God, and the right hand of God; for this reason is it said, "has He healed for Him." It is not said only, "His right hand has healed the world," but "has healed for Him." For many are healed for themselves, not for Him. Behold how many long for that bodily health, and receive it from Him: they are healed by Him, but not for Him. How are they healed by Him, and not for Him? When they have received health, they become wanton: they who when sick were chaste, when cured become adulterers: they who when in illness injured no man, on the recovery of their strength attack and crush the innocent: they are healed, but not unto Him. Who is he who is healed unto Him? He who is healed inwardly. Who is he that is healed inwardly? He who trusts in Him, that when he shall have been healed inwardly, reformed into a new man, afterwards this mortal flesh too, which does languish for a time, may in the end itself even recover its most perfect health. Let us therefore be healed for Him. But that we may be healed for Him, let us believe in His right hand.”

“O sing unto the Lord a new song,.... An excellent one unto the Lord Christ, on account of the great work of redemption and salvation wrought out by him; and because of the new and living way opened by him, and because of the new dispensation of the Gospel, which takes place through him, and for the reasons next mentioned; See Gill on Psa 96:1, for he hath done marvellous things; by assuming human nature, in that he, being God, became man, took flesh of a virgin, even pure and uncorrupted, a clean thing out of an unclean; which he took into personal union with himself, and that for the sake of sinful creatures: a most marvellous affair this! which calls for a new song from men, as it had from the angels. In this nature he taught wonderful doctrines, at which his hearers were astonished, wondering from whence he had his wisdom; and in it he did many miraculous works, which filled them with amazement above measure; and especially in it he performed the amazing and surprising work of man's redemption, an instance of the marvellous lovingkindness and astonishing wisdom of God; performed in a manner quite stupendous, through Christ's being made under the law both the precept and penalty of it; through his being made sin and a curse for men, even for the ungodly, sinners and enemies; a redemption which is of the souls of men from sin, Satan, and the law; a complete and plenteous one, which includes and secures all the blessings of grace and glory, justification, pardon, adoption, and eternal life. To which may be added the resurrection of himself from the dead, his ascension to heaven, the effusion of the extraordinary gifts of the Spirit on the apostles, the wonderful success of the Gospel in the Gentile world, the support of his interest against all the powers on earth, the destruction of the man of sin, the calling of the Jews, and the bringing in of the fulness of the Gentiles in the latter day; all which marvellous events require a new song of praise: another reason of which follows: his right hand and his holy arm hath gotten him the victory: over sin, Satan, the world, death, and hell, in which he has made his people sharers, yea, more than conquerors; and therefore may well sing the new triumphant song to him: the words may be rendered, "hath brought salvation to him" (b); as in Isa 59:16; to him personally, he raising himself from the dead, as a triumphant Conqueror; to him mystically, his body the church, to whom he is the author of salvation; or to him, that is, to his Father, in obedience to whose will he wrought out salvation for his people, and for the honour of his name, and for the glorifying of his perfections. This was done by him alone, by his right hand of power, by the mighty arm of his strength, and which no mere creature could ever have performed: and this he did in a way of holiness; his holy arm did it in a way that maintains and secures the glory of divine holiness and justice. (b) "salutem attulit ei", Junius & Tremellius, Piscator; so Tigurine version, Munster, Cocceius, Gejerus, Michaelis.”

“David. His name occurs not in Hebrew, though the psalm is worthy of him. (Berthier) — It may refer to the return from captivity, as a figure of the world’s redemption. — Things. In rescuing his people from slavery, and in the incarnation. (Calmet) — For him. Or alone. (Menochius) — Christ raised himself by his own power. (Calmet) (Isaias lxii. 5.) — He redeemed mankind for his own glory, sibi. (Berthier)”

“Psa 98:1 we have already read in Psa 96:1. What follows in Psa 98:1 is taken from Isa 52:10; Isa 63:5, cf. Psa 98:7, Psa 59:16, cf. Psa 40:10. The primary passage, Isa 52:10, shows that the Athnach of Psa 98:2 is correctly placed. לעיני is the opposite of hearsay (cf. Arab. l-l-‛yn, from one's own observation, opp. Arab. l-l-chbr, from the narrative of another person). The dative לבית ישראל depends upon ויּזכּר, according to Psa 106:45, cf. Luk 1:54.”
