What is the song of Moses and of the Lamb in Revelation 15?
It is the Song of the Sea from Exodus 15 sung again at history's end — the same redeemed people standing beside the same sea, singing the same victory over the same kind of enemy, now completed by the Lamb whose own blood purchased the singers.
Revelation 15 is not alluding to Exodus 15. It is naming it — and showing it sung to its completion.
John sees "those who had conquered the beast ... standing beside the sea of glass, and they sing the song of Moses the servant of God and the song of the Lamb" (Rev 15:2–3). The author of Revelation does not leave room for ambiguity. He names the song, names Moses, names the Lamb, and constructs the scene to be recognized: the redeemed standing beside the sea, the enemy overcome, the victory hymn rising. This is the Song of the Sea, placed deliberately at the end of the canon as its own consummation.
The scene's architecture is exact. At the Red Sea: Israel stands at the water's edge, Egypt's army lies dead, Moses leads the song. At the sea of glass: the redeemed of every nation stand before God's throne, the beast is overcome, the song of Moses is sung again — this time with an addition. The Song of the Sea was always incomplete: it declared YHWH's eternal reign (Exo 15:18) but could not yet name the one whose blood would purchase the people who sing it. Revelation 15 adds "and the song of the Lamb." The Exodus song reaches its destination.
"And they sing the song of Moses the servant of God and the song of the Lamb, saying: 'Great and wonderful are your works, O Lord God the Almighty! Just and true are your ways, O King of the nations!'"
— Rev 15:3
Three Lexical Bridges
The connection is not just thematic. Three specific words run from Exodus 15 to Revelation 15, and they travel through the ancient Greek translation (the Septuagint).
The wonder-word: "great and wonderful (θαυμαστά) are your works" (Rev 15:3) reaches back to the Song's declaration "doing wonders" (עֹשֵׂה פֶלֶא, H6382, Exo 15:11). The Greek word family θαυμαστός / θαύμα is the Septuagint's regular translation for פֶּלֶא ("wonders") across the Old Testament. The same wonder-word the Song first coined in the Torah as a descriptor of YHWH is the wonder-word Revelation places on the lips of the redeemed beside the throne.
The kingship-word: "O King (βασιλεύς) of the nations" (Rev 15:3) reaches back to "YHWH will reign forever and ever" (יִמְלֹךְ לְעֹלָם וָעֶד, Exo 15:18), through the Septuagint's rendering of that verb as βασιλεύων ("reigning"). What the Song declared as a future imperfect — will reign — arrives in Revelation as a cosmic title: King of the nations. The nations that trembled at the news of the crossing (Exo 15:14) now stand before the King they trembled at.
The sea itself: the physical Sea of Reeds has become the sea of glass mixed with fire (Rev 15:2) — the sea of judgment transformed into the throne's platform, now a place to stand rather than to drown.
Why It Is the Song of Moses AND the Lamb
The Song of the Sea was the first song. It was also the right song — it got the theology right from the beginning: the warrior who fights for his people, the incomparable God, the sanctuary at the end of the journey, the King who reigns forever. What it could not yet name was the Lamb.
At the Red Sea, the enemy was a human army. The rescue was a wind and a wall of water. The victory was decisive but temporary — Israel would sin, be exiled, return. The defeat was not final. At the sea of glass, the enemy is the beast — the last great power set against the people of God — and the victory is the Lamb's own death and resurrection. His blood is what purchased every nation standing at that shore. The Song of the Sea provided the form; the Lamb provided the ground. Revelation sings them together because together they are finally complete.
The reign that Exodus 15:18 declared beside the Red Sea — "YHWH will reign forever and ever" — is the reign announced accomplished in Revelation 11:15: "The kingdom of the world has become the kingdom of our Lord and of his Christ, and he will reign forever and ever." The words are the same. The voice behind them is the same. The sea is different, and everything it took to bring those singers to that shore is now visible.
The full study maps every thread — the warrior, the incomparable God, the sanctuary, the throne — from the shore of the Red Sea to the sea of glass.
What does 'Who is like you?' mean in Exodus 15?
It is the Bible's first incomparability question — a rhetorical declaration that no god, power, or ruler can be placed alongside YHWH, asked twice in a single verse because the sea crossing has just answered it empirically: the gods of Egypt are absent and their army is dead.
What does 'YHWH is a man of war' mean?
It is a declaration of God's permanent identity as a warrior-defender of his people, not merely a description of one battle — 'YHWH is a man of war; YHWH is his name' (Exo 15:3) is a standing title, not a past-tense report.
Who is Miriam the prophetess?
Miriam is the first woman in the entire Bible to be called a prophetess — and the title is given to her not in a throne room or temple, but in the act of leading Israel's women in victory praise at the Red Sea.
Why did Moses and Israel sing after the Red Sea?
Because the first thing the redeemed do, in the structure of Scripture, is sing — and praise, in the Bible, is born not in Eden but at the sea, the moment slaves who could not save themselves have just been saved.
