Revelation 15:2-3

ISV(i) 2 The Vision of the Sea of GlassThen I saw what looked like a sea of glass mixed with fire. Those who had conquered the beast, its image, and the number of its name were standing on the sea of glass holding God’s harps in their hands. 3 They sang the song of God’s servant Moses and the song of the lamb: “Your deeds are both spectacular and amazing, Lord God Almighty. Your ways are just and true, King of the nations.
