Moses sang in Exodus 15 the song of victory for Israel because they were delivered from the pursuing Egyptians. The apostle John calls this The Song of the Lamb as a song of victory for Christians over the final wrath of God in The Revelation of Jesus Christ, Chapter 15.
“And they sang the song of Moses, the bond-servant of God, and the song of the Lamb, saying,
“Great and marvelous are Your works,
O Lord God, the Almighty;
Righteous and true are Your ways,
King of the nations!
Who will not fear, O Lord, and glorify Your name?
For You alone are holy;
For all the nations will come and worship before You,
For Your righteous acts have been revealed.”
They sang both songs: one to remember the past and one to remember the present. So must we.
“Behold, I am coming soon, bringing my recompense with me, to repay each one for what he has done. I am the Alpha and the Omega, the first and the last, the beginning and the end.” Jesus
