Revelation 14:2; Revelation 15:2

And I heard a voice from heaven alike the roar of many waters and blike the sound of loud thunder. The voice I heard was like the sound of charpists playing on their harps,


And I saw twhat appeared to be a sea of glass mingled with fireand also those uwho had conquered the beast and its image and vthe number of its name, standing beside the sea of glass wwith harps of God in their hands.
