Revelation 15

1 witness of Christ here.

Lamb of God

Lamb — the sacrificial offering, Christ slain for sin; King of saints — sovereign of the holy ones

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. Revelation 15:3–4

Just as Israel sang the song of Moses after being delivered through the Red Sea, the redeemed sing the song of the Lamb after Christ delivers them from the beast. Moses the deliverer points to Christ, the greater Deliverer and King of saints.
