8261. Then sang Moses and the sons of Israel this song to Jehovah. That this signifies the glorification of the Lord by those who are of the spiritual church on account of liberation, is evident from the signification of "singing a song," as being a glorification (of which below); that it denotes the glorification of the Lord is because by "Jehovah" in the Word is meant the Lord (see n. 1343, 1736, 2921, 3023, 3035, 5041, 5663, 6280, 6281, 6905, 6945, 6956); and from the representation of Moses and the sons of Israel, as being those who are of the spiritual church; for Moses together with the people represent that church, Moses its head, because he also represents the Divine truth, and the people or the sons of Israel the church itself. (That "the sons of Israel" denote those who are of the spiritual church, see n. 6426, 6637, 6862, 7035, 7062, 7198, 7201, 7215, 7223.) That this glorification of the Lord is on account of liberation, is evident from what was shown in the preceding chapter; namely, that they who were of the spiritual church were saved solely by the coming of the Lord into the world, and that until then they had been detained in the lower earth, and there had been infested by spirits who were in falsities from evil, and were liberated by the Lord after He made the Human in Himself Divine. (That they who were of the spiritual church were saved solely by the coming of the Lord into the world, see n. 2661, 2716, 2833, 2834, 6372; and that until then they had been detained in the lower earth, and were liberated by the Lord when He made the Human in Himself Divine, n. 6854, 6914, 7035, 7091, 7828, 7932, 8018, 8054.)
 That "to sing a song" denotes to glorify, and that thus a "song" denotes a glorification, is because in the Ancient Church and afterward in the Jewish Church the songs were prophetic and treated of the Lord, especially that He would come into the world, and would overthrow the diabolical crew, then raging more than ever, and would liberate the faithful from their assaults. And because the prophetic utterances of the songs contained such things in the internal sense, therefore by these is signified a glorification of the Lord, that is, a celebration of Him from gladness of heart; for gladness of heart is especially expressed by a song, because in a song gladness breaks forth as it were of itself into sound. Hence it is that Jehovah-that is, the Lord-is called in songs "Hero," a "Man of war," the "God of armies," "Conqueror," "Strength," "Bulwark," "Shield," "Salvation;" and the diabolical crew that is overthrown, "the enemy" that is "smitten," "swallowed up," "overwhelmed," "cast into hell."
 They who knew nothing of the internal sense also believed in time past that such things as were in the world were meant, as worldly enemies, battles, victories, defeats, submersions, of which the songs treated in the external sense; but they who knew that all prophetic utterances involved things heavenly and Divine, and that these were represented in them, knew that the subject there treated of is the damnation of the unfaithful, and the salvation of the faithful by the Lord, when He would come into the world. And then those who knew this, and meditated upon it, and were affected thereby, had internal gladness; but others only external. The angels also who were with the men were at the same time in the glorification of the Lord; consequently they who sang, and they who heard the songs, had heavenly gladness from the holy and blessed influx which flowed in from heaven, in which they seemed to themselves to be as it were taken up into heaven. Such an effect had the songs of the church among the ancients. Such an effect also they would have at this day; for the spiritual angels are especially affected by songs which are about the Lord, His kingdom, and the church. That the songs of the church had this effect, was not only because by them gladness of heart became active, and burst forth from within even to the utmost fibers of the body, and set these in motion with a glad and at the same time a holy tremor; but also because there is a glorification of the Lord in the heavens by means of choirs, and thus by the harmonious music of many. From this also angelic speech is harmonious, falling into rhythmic measures. (Concerning choirs see n. 2595, 2596, 3350, 5182, 8115; and concerning angelic speech, that it falls into rhythmic measures, n. 1648, 1649, 7191e.) From this it is that the glorifications of the Lord among the ancients who were of the church were performed by means of songs, psalms, and musical instruments of various kinds; for the ancients who were of the church had a joy that surpassed all other joys from calling to mind the Lord's coming, and the salvation of the human race through Him.
 That in the internal sense the prophetic songs contained a glorification of the Lord, is evident from the songs in the Word, as in Isaiah:
I Jehovah have called thee in righteousness, and I will take hold of thy hand, I will guard thee, and give thee for a covenant to the people, for a light to the nations, to open the blind eyes, to bring out the bound one from the prison, him that sitteth in darkness out of the house of confinement: sing ye to Jehovah a new song, His praise, extremity of the earth; let the wilderness and the cities thereof lift up a voice, let the inhabitants of the rock sing, let them give glory to Jehovah; Jehovah shall go forth as a hero, as a man of wars; He shall stir up the zeal, He shall prevail over His enemies (Isa. 42:6, 7, 10-13);
it is evident that this treats of the Lord, in that He would come to liberate those who were in spiritual captivity; wherefore it is said, "sing to Jehovah a new song," and "let the inhabitants of the rock sing." In like manner in the same:
I have given thee for a covenant of the people, to restore the land, to divide the wasted heritages; to say to them that are bound, Go forth; to them that are in darkness, Be ye revealed: they shall feed upon the ways, and on all hillsides shall be their pasture. Sing, O ye heavens; and exult, O earth; and resound, ye mountains, with song, because Jehovah hath comforted His people, and will have mercy on his afflicted ones (Isa. 49:8, 9, 13);
here also the coming of the Lord and the liberation of the bound are treated of.
 In David:
Sing ye to Jehovah a new song, bless His name, recount His glory among the nations: all the gods of the peoples are vanities; but Jehovah made the heavens, glory and honor are before Him; strength and comeliness are in His sanctuary; give ye to Jehovah glory and strength, give ye to Jehovah the glory of His name; say ye among the nations, Jehovah reigneth, the world also is established, and it shall not be removed; Jehovah cometh, He cometh to judge the earth (Ps. 96).
Jehovah hath made me come up out of the pit of vastation, out of the mire of clay; and hath set my feet upon a rock; and He hath put a new song into my mouth, even praise to our God; many shall see, and shall trust (Ps. 40:2, 3).
From these words also it is evident that a "song" denotes a glorification of the Lord on account of liberation; for the songs involved gladness of heart, and the exaltation of the Lord-gladness of heart, on account of the Lord's coming and salvation then; and exaltation, on account of victory over spiritual enemies. Gladness of heart with exaltation of the Lord is what is meant by glorification.
 That gladness of heart was signified by "songs," is evident in these passages:
Confess ye to Jehovah on the harp, on a psaltery of ten strings, sing psalms to Him, sing ye to Him a new song; beat surpassingly with a loud noise, because He gathereth the waters of the sea together as a heap, He putteth the deeps in treasuries (Ps. 33:2, 3, 7).
The joy of timbrels shall cease, the tumult of them that are merry shall cease, the joy of the harp shall cease. They shall not drink wine with a song (Isa. 24:8, 9).
I will turn your feasts into mourning, and all your songs into lamentation (Amos 8:10).
That the exaltation of Jehovah, that is, of the Lord, was performed by means of songs, is plain in David:
David the servant of Jehovah, who spake unto Jehovah the words of this song: Jehovah, my strength, Jehovah is my rock, and my fortress, and my rescuer; my God, my rock in whom I trust; my shield, and the horn of my salvation, my refuge; I will call upon Jehovah, who is to be praised; then shall I be saved from mine enemies (Ps. 18:1-3).
Jehovah is my strength and my shield; whence in a song I will confess Him; Jehovah is their strength, and the strength of salvations of His anointed (Ps. 28:7, 8).
Thy salvation O God will bring me on high; I will praise the name of God with a song, and will magnify Him with confession (Ps. 69:29, 30).
 That the songs treated of the Lord, is evident also in John:
The twenty-four elders sang a new song, saying, Worthy art Thou who takest the book, and openest the seals thereof; because Thou wast slain, and hast redeemed us unto God with Thy blood (Rev. 5:8, 9).
I saw seven angels who sang the song of Moses the servant of God, and the song of the Lamb, saying, Great and marvelous are Thy works, O Lord, God the Almighty; just and true are Thy ways, O King of saints; who would not fear Thee, O Lord, and glorify Thy name? (Rev. 15:1, 2, 4);
"the song of Moses and of the Lamb" is the song which is in this chapter: it is called "the song of the Lamb," because the glorification of the Lord is treated of therein.
