Revelation 15:2-3

ACV(i) 2 And I saw like a glassy sea mingled with fire, and those who were victorious over the beast and over its image and over the number of its name, standing on the glassy sea, having harps of God. 3 And they sing the song of Moses the bondman of God, and the song of the Lamb, saying, Great and marvelous are thy works, Lord God Almighty, righteous and true are thy ways, thou King of the nations.
