Revelation 15:1-3

I saw in heaven another great and marvelous sign: seven angels with the seven last plagues—last, because with them God’s wrath is completed. And I saw what looked like a sea of glass glowing with fire and, standing beside the sea, those who had been victorious over the beast and its image and over the number of its name. They held harps given them by God and sang the song of God’s servant Moses and of the Lamb: “Great and marvelous are your deeds, Lord God Almighty. Just and true are your ways, King of the nations.
