1 Sing to Yahweh, a song that is new, For, wonderful things, hath he done, His own right hand and his holy arm, have brought him salvation.
Eusebius of Caesarea · AD 339 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.
Jerome · AD 420 Sing to the Lord a new song. The new song is the Son of God crucified, which had never before been heard. Let a new thing have a new song. Sing to the Lord a new song. He indeed is a man who suffered — but you, sing to the Lord. He suffered indeed as a man, but he saved as God. Sing to the Lord a new song. A new song deserves a new name.
Augustine of Hippo · AD 430 "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.
2 Yahweh, hath made known, his salvation, Before the eyes of the nations, hath he revealed his righteousness;
Jerome · AD 420 The Lord has made known his salvation. He did not say 'he showed,' but 'he made known.' What he says is this: what before they had known of God, and by their own fault had forgotten. Therefore God, coming by his grace, made manifest to them this thing which they had lost.
Augustine of Hippo · AD 430 "The Lord has made known His salvation" [Psalm 98:2]. This very right hand, this very arm, this very salvation, is our Lord Jesus Christ of whom it is said, "And all flesh shall see the salvation of God;" [Luke 3:6] of whom also that Simeon who embraced the Infant in his arms, spoke, "Lord, now let Your servant depart in peace; for my eyes have seen Your salvation." [Luke 2:28-…
3 He hath remembered his lovingkindness and his faithfulness towards the house of Israel,—All the ends of the earth, have seen, the salvation of our God.
Jerome · AD 420 He has remembered his mercy. 'He has shut up all things under sin, that he might have mercy on all.' And his truth to the house of Israel. He remembers mercy: he fulfills truth. He has remembered his mercy: that is, toward the people of the nations. And his truth to the house of Israel: fulfilling by this work what he had promised to the patriarchs.
Augustine of Hippo · AD 430 "He hath remembered His mercy to Jacob, and His truth unto the house of Israel" [Psalm 98:3]. What meaneth this, "He hath remembered His mercy and truth"? He hath pitied, so that He promised; because He promised and showed His mercy, truth hath followed: mercy hath gone before promise, promise hath been fulfilled in truth....
4 Shout aloud to Yahweh, all the earth, Break forth and make a joyful noise and sweep the strings;
Jerome · AD 420 Rejoice in God, all the earth. Not Judea alone, but all the earth — rejoice in the Lord. Send forth the standards of the victorious army. Sing and exult and make melody. Sing — in thought; but make melody — that is, with all your members. Let the hand make melody in almsgiving, let the foot make melody by going about in good work.
Peter Chrysologus · AD 450 "Sing joyfully to God, all the earth." What is it that an understanding of this great joy is likely to make clear? Why is it that, after God gave commandments so great, so terrifying and so awesome, he now invites the earth to a shout of joy? "Sing joyfully to God, all the earth," the text reads.What other reason is there than the following?
Cassiodorus · AD 585 The phrase "Sing and exult and play the lyre" follows. Although these words seem to be similar, nonetheless they are separated by some distinction. Singing is shouting the praises to the Lord, as is befitting for the mouth of a serious Christian to do. Exulting is declaring the vows of the mind with great affection.
5 Sweep the strings to Yahweh, With the lyre, With the lyre, and the voice of melody;
Jerome · AD 420 Make melody to the Lord on the harp. Let all your strings have voice. There cannot be a harp if one string is missing. What does it profit you if you are chaste, and yet greedy? What does it profit you if you are both chaste and generous in almsgiving, and yet envious? What does it profit you if you have six strings whole and one broken?
Augustine of Hippo · AD 430 "Make melody unto the Lord upon the harp: on the harp and with the voice of a Psalm" [Psalm 98:5]. Praise Him not with the voice only; take up works, that ye may not only sing, but work also. He who singeth and worketh, maketh melody with psaltery and upon the harp.
6 With trumpets and the sound of a horn, Shout aloud, before the king—Yahweh.
Jerome · AD 420 On beaten trumpets and with the sound of the horned trumpet. We read in the book of Numbers that there are two kinds of trumpets: one kind of trumpet beaten out of silver, and another kind of trumpets made of horn. So here both are named: On beaten trumpets and with the sound of the horned trumpet. What is said is this. The trumpet beaten out of silver is the word of God.
7 Let the sea, roar, and the fulness thereof, The world, and they who dwell therein;
Jerome · AD 420 Let the sea be moved, and the fullness thereof. Let the sea be moved, and let the bitter waters be changed into sweet. In fact, Marah too was changed and made into a sweet taste. Nothing else made that bitter water sweet except the wood of the cross, which had been cast into it. It seems to me that the bitter sea is the law of Moses.
Augustine of Hippo · AD 430 While ye are rejoicing, and delighted with the ductile trumpets, and the voice of the horn, what followeth? "Let the sea be stirred up, and the fulness thereof" (ver. 7). Brethren, when the Apostles, like ductile trumpets and horns, were preaching the truth, the sea was stirred up, its waves arose, tempests increased, persecutions of the Church took place.
8 Let, the floods, clap their hands, Together, let, the mountains, make a joyful noise,
Jerome · AD 420 The rivers shall clap their hands together. Let us ask the Jews, who understand according to the letter. Do rivers have hands? Do rivers have voices? Do rivers have feet? Do rivers have a belly? Someone may say: It is not written about a belly, about feet.
9 Before Yahweh, for he is coming—to judge the earth,—He will judge the world, in righteousness, And the peoples, with equity.
Eusebius of Caesarea · AD 339 It is prophesied here that the coming of the Lord will be the cause of great benefits to the nations, which have been proved to have actually accrued to them, through the manifestation of our Savior.
Jerome · AD 420 He shall judge the world in righteousness, and the peoples in equity. Righteousness is set down, and equity. If righteousness is set down, and afterward equity, it is properly called εὐθύτης (euthytēs), 'straightness,' which makes the crooked straight. So he comes to judge in his righteousness, that what is crooked may in him be made straight.
Augustine of Hippo · AD 430 "Before the Lord, for He has come; for He has come to judge the earth" [Psalm 98:9]. "The hills" signify the great. The Lord comes to judge the earth, and they rejoice. But there are hills, who, when the Lord is coming to judge the earth, shall tremble. There are therefore good and evil hills; the good hills, are spiritual greatness; the bad hills, are the swelling of pride.
