'Clear' in the Bible

In front of the throne was something like a sea of glass as clear as crystal. In the center of the throne and on each side of the throne were four living creatures full of eyes in front and in back.

The glory of God was its radiance, and its light was like a valuable gem, like jasper, as clear as crystal.

Its wall was made of jasper. The city was made of pure gold, as clear as glass.

The twelve gates were twelve pearls, and each gate was made of a single pearl. The street of the city was made of pure gold, as clear as glass.

Then the angel showed me the river of the water of life, as clear as crystal. It was flowing from the throne of God and the lamb.
