Revelation 15:2-3

2Then I saw what seemed to be a glass sea. Fire was mixed in it. I also saw people who were standing at the edge of the glass sea. Those people had fought against the wild animal and they had won. They had won against its image and the number that means its name. They had fought and they had won. God had given them harps. They held the harps to make music.

3Now they sang the song of God's servant, Moses, and the Lamb's song. They sang this: ‘Lord God with all power, what you do is great and wonderful! Everything that you do is completely fair and honest. You are King of all nations of the world.
