[2] This is the reason that many kinds of musical instruments were used in sacred worship among the Jewish and Israelitish nation, of which some had reference to the affections of celestial good, and some to the affections of spiritual good, and to the joys thence, which were spread abroad. The stringed instruments had reference to the affections of spiritual good, and the wind instruments to the affections of celestial good, to which also singing with songs was associated, by which things agreeing with the sounds of the affections were formed. All the psalms of David were of this nature, therefore they are called psalms (psalmi), from playing, (psallere), and also songs. From these considerations it may also be evident why it is said that the four animals and twenty-four elders had harps, and also sang this song.

[3] That singing and to sing a song, signify acknowledgment and confession from joy of heart, appears from the following passages. In Isaiah:

"In that day thou shalt say, I will confess Jehovah, O God of my salvation, I will trust, I will not be afraid; for Jah is my strength and song; Jehovah was my salvation. Then ye shall draw waters out of the wells of salvation. And in that day ye shall say, Confess Jehovah, call upon his name, sing unto Jehovah. Cry out and shout, thou inhabitant of Zion, for great is the Holy One of Israel in the midst of thee" (xii. 1-6).

Thus is described confession from joy of heart on account of the Lord's advent, and His Divine power in saving the human race. That it denotes confession is evident, for it is first said, I will confess Jehovah, and also, afterwards, confess Jehovah. The confession, that the Lord from His Divine power would save mankind, is described by these words, "God of my salvation, I will trust, I will not be afraid, for he is my strength, he also was my salvation. Then ye shall draw waters out of the wells of salvation in that day; great is the Holy One of Israel in the midst of thee." In that day, denotes when the Lord shall come; the Holy One of Israel is the Lord; the joy thence, which is the joy of confession, is described by, Sing unto Jehovah, cry out and shout, thou inhabitant of Zion; the inhabitant and daughter of Zion denote the church, where the Lord is worshipped. The song Jah, signifies the celebration and glorification of the Lord.

[4] In the same:

"Sing unto Jehovah a new song, his praise, O end of the earth. Let the wilderness and the cities thereof lift up their voice, let the inhabitants of the rock sing, let them shout from the top of the mountains" (xlii. 10, 11).

Here also the Lord's advent is treated of, and the establishment of the church among those who were outside the church or with those where the Word was not, and the Lord was not before known. To sing a new song, signifies confession from joy of heart; to sing praise, O end of the earth, signifies the confession of those who are remote from the church; the end of the earth is where that which pertains to the church terminates, the earth denoting the church; the wilderness and the cities thereof which lift up the voice, signify those with whom there is no good because there is no truth, which they nevertheless desire: the inhabitants of the rock, signify the good of faith pertaining to them; the top of the mountains, signifies the good of love pertaining to them: to sing and to shout, signify confession thence from joy of mind and heart.

[5] In the same:

"Jehovah shall comfort Zion; he will comfort all her waste places; and he will make her wilderness like Eden, and her solitude like the garden of Jehovah; joy and gladness shall be found therein, confession and the voice of singing" (li. 3: lii. 8, 9).

These words also refer to the Lord's advent and the establishment of the church, which at that time was vastated or destroyed. By Zion is signified the church where the Lord is to be worshipped; by her waste places is signified a lack of truth and good from a want of knowledge; by making her wilderness like Eden, and her solitude like the garden of Jehovah, is signified that they shall have truth and good in abundance; wilderness is predicated of the want of good, and solitude of the want of truth; Eden signifies good in abundance, and the garden of Jehovah signifies truth in abundance. Because singing and a song signify confession from joy of heart, therefore it is said joy and gladness shall be therein, confession and the voice of singing; the voice of singing denoting [the same as] a song.

[6] In Lamentations:

"The elders have ceased from the gate, the young men from singing. The joy of our heart has ceased" (v. 14, 15).

The elders have ceased from the gate, signifies that those who are in truths from good, or, in the abstract, truths from good, by which introduction into the church takes place, are no more; the young men have ceased from singing, signifies that truths themselves are deprived of their spiritual affection, and thence of their joy; and because this is signified it is said, "The joy of our heart has ceased."

[7] In Ezekiel:

"I will cause the noise of thy songs to cease: and the sound of the harps shall be no more heard" (xxvi. 13).

The noise of the songs signifies the joys of confessions: the sound of the harps signifies gladness from spiritual truths and goods.

[8] In David:

"Jehovah is my strength and my shield; my heart rejoiceth, and with my song will I confess him" (xxviii. 7).

Because a song signifies confession from joy of heart, therefore it is said, "my heart rejoiceth, and with my song will I confess him."

[9] In the same:

"Sing, ye just in Jehovah. Confess Jehovah upon the harp; sing unto him with an instrument of ten strings. Sing unto him a new song; play excellently with a loud noise" (Ps. xxxiii. 1-3).

Because joy of heart arises from celestial and spiritual love, it is therefore said, "Sing, ye just in Jehovah: confess Jehovah upon the harp: sing unto him with an instrument of ten strings." Sing, ye just is predicated of those who are in celestial love: confess upon the harp and play upon the psaltery, of those who are in spiritual love. That they are called just who are in celestial love, may be seen above, n. 204, and that the harp and psaltery are predicated of those who are in spiritual good, n. 323. And because singing denotes confession from the joy arising from those loves, therefore it is said, "Confess Jehovah, sing unto him a new song." The exaltation of joy from its fulness is signified by play excellently with a loud noise.

[10] In the same:

"I will praise the name of God with a song, and will magnify him by confession" (Ps. lxix. 30).

Again:

"When I shall have gone with them to the house of God with the voice of singing and confession; the multitude keeping holiday" (Ps. xlii. 4).

Again:

"Confess ye Jehovah; call upon his name. Sing unto him, sing psalms unto him" (Ps. cv. 1, 2: cxlix. 1).

Again:

"I will confess Jehovah according to his justice; and I will sing unto the name of Jehovah most high" (Ps. vii. 17).

Again:

My heart is fixed, O God, my heart is prepared; I will praise. Awake, my glory; awake, psaltery and harp. I will confess thee, O Lord, among the nations; I will sing unto thee among the peoples" (Ps. lvii. 7-9).

Because to sing a song signifies confession from joy of heart, therefore in these passages two expressions are used, to confess and to sing, confession and a song, the voice of singing and of confession.

[11] Where the Lord's advent is treated of a new song is spoken of, and that the earth, the sea, the field, the forest, the trees, Lebanon, the wilderness, and many other things, should rejoice and exult, as in the following passages: In David:

"O sing unto Jehovah a new song. Make a loud noise unto Jehovah, all the earth; play, rejoice, and sing, with the harp and the voice of a song: with trumpets, and with the sound of the horn, make a loud noise before Jehovah the King. Let the sea and all the fulness thereof give forth a sound: the world, and they that dwell therein. Let the floods clap their hands: let the mountains be joyful together" (Ps. xcviii. 1, 4-8).

Again:

"O sing unto Jehovah a new song; sing unto Jehovah, all the earth. Sing unto Jehovah, bless his name: make known his salvation from day to day. The heavens shall be glad and the earth shall rejoice: the sea shall be moved and all the fulness thereof: the field shall exult and all that is therein, then shall all the trees of the forest sing" (Ps. xcvi. 1, 2, 11, 12).

Again:

Sing unto Jehovah a new song, his praise in the congregation of the saints. Let Israel rejoice in his makers, the sons of Zion in their King. Let them praise his name in the dance: let them sing praises unto him with the timbrel and harp" (Ps. cxlix. 1-3).

In Isaiah:

"Sing unto Jehovah a new song; his praise, ye ends of the earth. Let the wilderness and the cities thereof lift up the voice " (xliii. 10, 11).

Again:

"Sing, O ye heavens, for Jehovah hath done it; shout, ye lower parts of the earth; break forth into singing, ye mountains, forest, and every tree therein; for Jehovah hath redeemed Jacob, and hath shown himself glorious in Israel " (xliv. 23; xlix. 13).

The subjects treated of in these passages are the Lord, His advent, and salvation by Him; and because these things were about to take place, therefore a new song is mentioned; the joy thence arising is described not only by singing, playing, making a loud noise, being joyful, clapping the hands, but also by various musical instruments, which in sound are in agreement. So also that the rivers, the sea, the field, the forests, the trees therein, Lebanon, the wilderness, the mountains, and many other things, should rejoice, exult, be joyful, sing, clap the hands, and cry aloud together.

The reason why similar things are predicated of those objects is, because they signify such things as pertain to the church, and, consequently, such things as the man of the church possesses: the rivers, the things of intelligence: the sea, the things of science, which are in agreement with truths and goods; the field, the good of the church: forests, the truths of the natural man; the trees, knowledges; Lebanon, spiritual truth and good: the wilderness, the desire of truth that thence good may be attained; and the mountains, the goods of love. All these things are said to sing, to make a loud noise, to rejoice, to cry aloud and clap the hands, when they are from heaven, for then heavenly joy is in them, and thereby in man; for man is not in heavenly joy unless those things which he possesses, which are truths and goods, are from heaven, hence the joy of heart, which is truly joy, and the joy of the man with whom these things are. It is, consequently, evident why it is that the same is said of them as of man, namely, because joy is in them and thereby in man; such Joy is in every spiritual and celestial good, and thence in those with whom those goods are: for heaven flows in with its joy, that is, the Lord through heaven, into the goods and the truths thence, which are from Him with man, and thereby into the man, and not into the man destitute of or without them. Those goods and the truths thence are what from influx out of heaven exult, rejoice, make a loud noise, sing, play, that is, are glad, and thence [affect] the heart of man.

[12] Because there are various affections of good and truth, and each expresses itself by an appropriate sound, therefore in the Word, especially in David, various kinds of instruments are mentioned, by which similar affections are signified. He who has become acquainted with the internal sense of the Word, and at the same time with the sounds of the instruments there named, may know the particular affection that is there signified and described; the angels know this from the mention of them alone, and at the same time from the thing described there in its own expressions, when one reads the Word. Thus, for example, in David:

"Clap your hands, all ye peoples; sing together unto God with the voice of a song; God is gone up with a shout, Jehovah with the voice of a trumpet; Sing unto God, sing unto our King, for God is the King of all the earth; sing ye with understanding" (Ps. xlvii. 1, 5-7).

Again:

"They have seen thy goings, O God; the goings of my God. The singers went before, the players on instruments after, in the midst of the virgins playing with timbrels" (Ps. lxviii. 24, 25).

Again:

"Shout unto God our strength; call unto the God of Jacob. Raise a song, and strike the timbrel, the pleasant harp with the psaltery. Blow the trumpet in the month" (Ps. lxxxi. 1-3).

Again:

"Praise God with the sound of the trumpet; with the psaltery and harp; with the timbrel and dance; with the lute and the organ, with the soft cymbals; and with the loud cymbals" (Ps. cl. 1, 3-5).

All the instruments here mentioned signify affections, each its own, and this from the agreement of their sound: for it is the affections that produce the varieties of sounds with men, whence the affections are also known from the sounds, as said above in this article.

[13] To these observations I will add an arcanum: the angels who in heaven constitute the Lord's celestial kingdom, draw the internal sense of the Word from the affection alone of a man when he reads the Word; this results also from the sound of the expressions in the original tongue. But the angels who are in the Lord's spiritual kingdom, draw the internal sense from the truths which the expressions contain; hence from the celestial kingdom, the man who is in spiritual affection has joy of heart: and from the spiritual kingdom, confession from that joy. The sounds of the musical instruments that are there mentioned, elevate the affection, and the truths from it. That this is so, those skilled in the art of music know. For this reason the Psalms of David are called psalms (psalmi) from playing (psallere), and also songs from singing; for they were played and sung with the sounds of various instruments. That they were called Psalms by David is known, because several of them are so inscribed. Those, however, that are called songs, are the following: Ps. xviii. 1; xxxiii. 1, 2; xlv. 1; xlvi. 1: xlviii. 1: lxv. 1: lxvi. 1: lxvii. 1: lxviii. 1; lxxv. 1: lxxvi. 1; [lxxxiii. 1;] lxxxvii. 1; lxxxviii. 1; xcii. 1; xcvi. 1: xcviii. 1; cviii. 1; cxx. 1; cxxi. 1; cxxii. 1; cxxiii. 1; cxxiv. 1 cxxv. 1: cxxvi. 1: cxxvii. 1: cxxviii. 1: cxxix. 1; cxxx. 1; cxxxi. 1; cxxxii. 1: cxxxiii. 1; cxxxiv. 1. Many other passages might be adduced from the Word respecting singing and a song, and it might be shown that they signify confessions from joy of heart: they are omitted because of their number; those adduced are sufficient.
