Revelation 15:2-3 And I saw as it were a sea of glass mingled with fire. And those who had gotten the victory over the beast, and over his image, and over his mark, and over the number of his name, stand on the sea of glass, having the harps of God.

MKJV⁽ⁱ⁾ ² And I saw as it were a sea of glass mingled with fire. And those who had gotten the victory over the beast, and over his image, and over his mark, and over the number of his name, stand on the sea of glass, having the 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 Your works, Lord God Almighty, just and true are Your ways, O King of saints.
