Rev 4:6 and before the throne there was as it were a sea of glass, like crystal.And around the throne, on each side of the throne, are four living creatures, full of eyes in front and behind:
Rev 15:2 And I saw what appeared to be a sea of glass mingled with fire—and also those who had conquered the beast and its image and the number of its name, standing beside the sea of glass with harps of God in their hands.
