Verse-by-Verse Commentary
The Book of Revelation
Chapter 15: The Song of Moses and the Lamb
Revelation 15 is the shortest chapter of the book, a solemn prelude to the final judgments. John sees 'seven angels having the seven last plagues; for in them is filled up the wrath of God.' Before the plagues fall, he sees the victors, 'them that had gotten the victory over the beast,' standing on a sea of glass mingled with fire, holding the harps of God. They sing 'the song of Moses the servant of God, and the song of the Lamb,' praising the one true God: 'Great and marvellous are thy works, Lord God Almighty; just and true are thy ways... for thou only art holy: for all nations shall come and worship before thee.' Then the heavenly temple opens, seven angels come out with seven golden vials 'full of the wrath of God,' and the temple is filled with smoke from His glory. God's judgments are just, His holiness alone is complete, and His wrath is now filled up to the full.

Setting the Stage
Seven Last Plagues
In them "is filled up the wrath of God."
Over the Beast
They stand on the sea of glass with the harps of God.
Of Moses and the Lamb
"Just and true are thy ways... thou only art holy."
Filled With Glory
Seven golden vials of wrath, and the smoke of God's glory.
Thou Only Art Holy (Revelation 15:1-4)
Those who conquered the beast stand victorious before God and sing the song of Moses and the Lamb, praising the one holy God whose works are great, whose ways are just and true, and whom all nations shall worship.
Just and True Are Thy Ways
"And I saw another sign in heaven, great and marvellous, seven angels having the seven last plagues; for in them is filled up the wrath of God. And I saw as it were a sea of glass mingled with fire: and them that had gotten the victory over the beast, and over his image, and over his mark, and over the number of his name, stand on the sea of glass, having the harps of God. And they sing the song of Moses the servant of God, and the song of the Lamb, saying, Great and marvellous are thy works, Lord God Almighty; just and true are thy ways, thou King of saints. Who shall not fear thee, O Lord, and glorify thy name? for thou only art holy: for all nations shall come and worship before thee; for thy judgments are made manifest."
Word Study
"holy," Greek hosios (ὅσιος). The word speaks of what is holy, pure, and set apart in perfect goodness; here it declares that God alone possesses holiness in its fullness: "for thou only art holy." The song of the redeemed reaches its climax not in their own victory but in God's unique and absolute holiness. He alone is holy in the complete and underived sense, holy in His very being, holy in all His works, holy in every judgment. This is the same truth cried by the living creatures, "Holy, holy, holy, Lord God Almighty" (4:8), and by the seraphim before Isaiah (Isaiah 6:3): the one God is utterly, exclusively holy. And it is precisely because He alone is holy that "his ways" are "just and true" and His "judgments are made manifest." God's coming wrath is not cruelty or caprice; it flows from His perfect holiness, and so it is perfectly right. The redeemed, who have suffered under the beast, do not question God's justice; they praise it, "just and true are thy ways." And they foresee the result: "all nations shall come and worship before thee." The holiness of the one God, vindicated in His judgments, will draw the worship of the nations. So hosios anchors the whole scene: God alone is holy, therefore His ways are just and true, therefore He is worthy of the fear, the glory, and the worship of every nation. The song of the saints is a song about the holiness of the one Lord God.
Explanation
Before the last seven plagues, John sees the victors over the beast standing by "a sea of glass mingled with fire," singing "the song of Moses... and the song of the Lamb." The pairing binds the two great redemptions: as Israel sang after crossing the Red Sea and Pharaoh's defeat, so the redeemed sing after their greater Exodus through the blood of the Lamb. Their song exalts God's justice and holiness -- "Just and true are thy ways... for all nations shall come and worship before thee." Even on the brink of final wrath, heaven's focus is worship of the God whose judgments are righteous and whose salvation is complete.
Gospel Focus
Before the last plagues fall, God shows John the end from the beginning: the victors are already safe and singing. "Them that had gotten the victory over the beast, and over his image, and over his mark," those who refused to worship the beast whatever it cost, "stand on the sea of glass," the crystal floor before God's throne (4:6), now "mingled with fire," for they have come through the fire of tribulation. They hold "the harps of God" and sing "the song of Moses the servant of God, and the song of the Lamb." This is a beautiful and telling union. Moses' song was sung at the Red Sea, when God drowned Pharaoh and delivered Israel (Exodus 15); the Lamb's song is the song of redemption by the blood of Christ. The two are named together as one song, for they celebrate one great salvation by the one God: the God who delivered Israel from Pharaoh is the same God who delivered us through the Lamb, the one Lord God, Redeemer of both. Their praise centers wholly on God: "Great and marvellous are thy works, Lord God Almighty; just and true are thy ways, thou King of saints." They call Him "Lord God Almighty," the eternal all-ruler, and marvel that "thou only art holy." And they look beyond judgment to the great harvest: "all nations shall come and worship before thee; for thy judgments are made manifest." Even the manifestation of God's judgments will lead the nations to worship Him. For the Apostolic reader this is deeply reassuring: those who stand firm against the world's idolatry, refusing the beast's mark at any cost, are the ones who stand victorious before God, singing of His holiness and His salvation. Faithfulness leads not to loss but to the sea of glass and the harps of God.
Filled Up the Wrath of God (Revelation 15:5-8)
The heavenly temple opens, and seven angels come out with seven golden vials full of the wrath of God, while the temple is filled with the smoke of His glory, for His final judgments are about to be poured out.
The Temple Filled With the Glory of God
"And after that I looked, and, behold, the temple of the tabernacle of the testimony in heaven was opened: And the seven angels came out of the temple, having the seven plagues, clothed in pure and white linen, and having their breasts girded with golden girdles. And one of the four beasts gave unto the seven angels seven golden vials full of the wrath of God, who liveth for ever and ever. And the temple was filled with smoke from the glory of God, and from his power; and no man was able to enter into the temple, till the seven plagues of the seven angels were fulfilled."
Word Study
"wrath," Greek thymos (θυμός). The word denotes intense, settled indignation, the burning, righteous anger of God against sin, here "filled up" and poured out in full. Twice the chapter stresses that with these plagues God's wrath reaches its completion: "in them is filled up the wrath of God" (15:1), and the vials are "full of the wrath of God" (15:7). Earlier judgments, the seals and trumpets, were partial, striking "the third part," restrained and warning. These are different: they are the last plagues, in which the cup of divine wrath, long held back in patience, is finally poured out to the full. This is a solemn and necessary truth about the one true God. He is love, and He is holy; and precisely because He is holy, His wrath against unrepented sin is real, righteous, and, at the last, complete. The thymos of God is not the petty temper of men but the pure and settled opposition of perfect holiness to all evil. That God's wrath is at last "filled up" is the vindication of His justice: sin will not go unanswered forever, the martyrs' cry "How long?" will be answered in full, and every wrong will be set right. Yet the timing preaches mercy too: for ages God restrained His full wrath, giving space to repent. Now the restraint is ending. So thymos presses the urgency of the gospel: the day comes when God's wrath is poured out without mixture, and the only refuge is the blood of the Lamb, in whom the believer is forever safe from the wrath to come (1 Thessalonians 1:10).
Explanation
The temple in heaven opens, and seven angels emerge with the golden vials of "the wrath of God," and the sanctuary is "filled with smoke from the glory of God" so that none can enter until the plagues are finished. The smoke recalls the glory that filled the tabernacle and temple, now signaling that the hour of unmixed judgment has come and cannot be halted. There is a solemn finality here: access is closed, intercession's day is past, and the holiness of God will be fully vindicated. The God who was long patient now acts decisively, and His glory itself bars the way until justice is done.
Gospel Focus
John sees "the temple of the tabernacle of the testimony in heaven" opened, the heavenly sanctuary that the earthly tabernacle only copied, the place of God's holy presence and covenant. Out of it come "seven angels... having the seven plagues, clothed in pure and white linen," their purity marking that these judgments proceed from the holiness of God, not from malice. "One of the four beasts gave unto the seven angels seven golden vials full of the wrath of God, who liveth for ever and ever." The judgments come from the very presence of the eternal God, dispensed by His holy creatures, poured from golden vials, precious and deliberate, not random destruction but the measured justice of the living God. Then a striking thing: "the temple was filled with smoke from the glory of God, and from his power; and no man was able to enter into the temple, till the seven plagues... were fulfilled." The smoke of God's glory, as at Sinai (Exodus 19:18) and at the dedication of tabernacle and temple (Exodus 40:34-35; 1 Kings 8:10-11), so fills the sanctuary that none may enter until the judgments are complete. This signifies the awful finality of this hour: while God's final wrath is being poured out, the season of intercession within the sanctuary is, as it were, suspended; the time for mediation and repentance has run its course, and judgment must now be fulfilled. It is a sobering picture of the seriousness of the day of the Lord. For the believer, however, the chapter has already given the answer: the victors stand safe on the sea of glass, singing, while the vials are readied. The wrath of God is real and, at the last, complete; but those who are washed in the blood of the Lamb are not appointed to that wrath. The urgent word to all is the same the whole book has sounded: come to the Lamb now, while the door still stands open, and be found among the victors who sing, and not among those on whom the vials are poured.
Chapter 15 in Review
Revelation 15, the book's shortest chapter, is the prelude to the final judgments. John sees "seven angels having the seven last plagues; for in them is filled up the wrath of God." But first he sees the victors, "them that had gotten the victory over the beast," standing on a "sea of glass mingled with fire" with "the harps of God," singing "the song of Moses the servant of God, and the song of the Lamb": "Great and marvellous are thy works, Lord God Almighty; just and true are thy ways... for thou only art holy: for all nations shall come and worship before thee." Then the heavenly temple opens, seven angels come out with "seven golden vials full of the wrath of God," and "the temple was filled with smoke from the glory of God," so that "no man was able to enter... till the seven plagues... were fulfilled."
For the Apostolic reader this brief chapter holds together God's justice and His salvation. The song of Moses and the Lamb, named as one song, unites the two great deliverances, the Red Sea and Calvary, and confesses that both are the work of the one Lord God, who saved Israel from Pharaoh and saves us through the blood of the Lamb. The redeemed do not recoil from God's judgments; they praise them: "just and true are thy ways," for "thou only art holy." God's coming wrath is not cruelty but the outflow of His perfect holiness, and it is at last "filled up," complete, no longer partial or restrained. This is a sober warning, the day comes when the cup of wrath is poured out without mixture, and the smoke of God's glory fills the temple until judgment is done. Yet the same chapter shows the safety of the faithful: those who overcame the beast, refusing its mark at every cost, stand victorious on the sea of glass, singing. The two destinies are unmistakable. So we take our place with the victors: we refuse the world's idolatry, we trust the blood of the Lamb that saves us from the wrath to come, and we join even now the song of Moses and the Lamb, praising the one holy God whose works are great and whose ways are just and true.
