And they sung as it were a new canticle, before the throne, and before the four living creatures, and the ancients; and no man could say the canticle, but those hundred forty-four thousand, who were purchased from the earth.

“If I remember not that it is I who have served Him, how shall I ascribe glory to God? How sing to Him "the new song," if I am ignorant that it is I who owe Him thanks? But why is exception taken only against the change of the flesh, and not of the soul also, which in all things is superior to the flesh? How happens it, that the self-same soul which in our present flesh has gone through all life's course, which has learnt the knowledge of God, and put on Christ, and sown the hope of salvation in this flesh, must reap its harvest in another flesh of which we know nothing? Verily that must be a most highly favoured flesh, which shall have the enjoyment of life at so gratuitous a rate! But if the soul is not to be changed also, then there is no resurrection of the soul; nor will it be believed to have itself risen, unless it has risen some different thing.”

“And they sung as it were a new song,.... The song of redeeming grace; the same with that in Rev 5:9; see the note there: this is to be understood of the 144,000, who sung it before the throne, and before the four beasts and the elders; that is, publicly in the church, the ministers and members being present; of these; See Gill on Rev 4:4; See Gill on Rev 4:6; and no man could learn that song but the hundred and forty and four thousand, which were redeemed from the earth; out of every kindred, tongue, people, and nation; from among the men of the earth, and out of the apostate church, called the earth, in opposition to the pure church, which so often goes by the name of heaven in this book; and these, in consequence of being redeemed by the blood of Christ, were called by grace out of the world; and such only can sing the song of redemption with application to themselves; and say he has redeemed us, and loved us, and washed us from our sins in his blood; to none but these is it given to know spiritually and experimentally the mysteries of electing and redeeming grace; the natural and carnal man neither knows nor receives the things of the Spirit of God; nor can he learn them by hearing, reading, study, and conversation, unless it be only in a notional and speculative way. The Jews speak of a new song, which the angels have never used (m); "it is said, Psa 98:1; "sing unto the Lord a new song"; a new song, for there is an old song; but this song is what the angels never praised him with, and therefore it is new;'' and indeed the song of redeeming love is peculiar to men. (m) Zohar in Numb. fol. 70. 4.”

“They sung - a new song - See on Rev 5:9 (note). No man could learn that song - As none but genuine Christians can worship God acceptably, because they approach him through the only Mediator, so none can understand the deep things of God but such; nor can others know the cause why true believers exult so much in God through Christ, because they know not the communion which such hold with the Father and the Son through the Holy Ghost.”

“They sung as it were a new canticle. In these visions, after persecutions, are sometimes introduced rejoicings to encourage the servants of God in their sufferings from the wicked world. — No man could say (or sing) the canticle, but those hundred and forty-four thousand : by which are signified the elect, who were not defiled with women. Some expound this literally of those who always lived virgins; others understand all those who lived or died with a pure and clean heart, exempt from the corruption of vices, and of whom it is said, (ver. 5) that in their mouth was found no lie, and that they were without spot for the throne of God. (Witham)”

“sung--Greek, "sing." as it were--So A, C, and Vulgate read. It is "as it were" a new song; for it is, in truth, as old as God's eternal purpose. But B, Syriac, Coptic, ORIGEN, and ANDREAS omit these words. new song-- (Rev 5:9-10). The song is that of victory after conflict with the dragon, beast, and false prophet: never sung before, for such a conflict had never been fought before; therefore new: till now the kingdom of Christ on earth had been usurped; they sing the new song in anticipation of His blood-bought kingdom with His saints. four beasts--rather, as Greek, "four living creatures." The harpers and singers evidently include the 144,000: so the parallel proves (Rev 15:2-3), where the same act is attributed to the general company of the saints, the harvest (Rev 14:15) from all nations. Not as ALFORD, "the harpers and song are in heaven, but the 144,000 are on earth." redeemed--literally, "purchased." Not even the angels can learn that song, for they know not experimentally what it is to have "come out of the great tribulation, and washed their robes white in the blood of the Lamb" (Rev 7:14).”
