Revelation 15
2 Ref And I saw a sea which seemed like glass mixed with fire; and those who had overcome the beast and his image and the number of his name, were in their places by the sea of glass, with God's instruments of music in their hands.
3 Ref And they give the song of Moses, the servant of God, and the song of the Lamb, saying, Great and full of wonder are your works, O Lord God, Ruler of all; true and full of righteousness are your ways, eternal King.
