Revelation 15:2-3

ERV(i) 2 And I saw as it were a glassy sea mingled with fire; and them that come victorious from the beast, and from his image, and from the number of his name, standing by the glassy sea, having harps of God. 3 And they sing the song of Moses the servant of God, and the song of the Lamb, saying, Great and marvelous are thy works, O Lord God, the Almighty; righteous and true are thy ways, thou King of the ages.
