G5193–ὑάλινος–hualinos

Before the throne was something like a sea of glass, similar to crystal. In the midst of the throne, and around the throne were four living creatures full of eyes before and behind.

ὑαλίνη, hu'alinē “of glass,”

I saw something like a sea of glass mixed with fire, and those who overcame the beast, his image, and the number of his name, standing on the sea of glass, having harps of God.
