And over the head of the living creature there was the likeness of a firmament, like the terrible crystal to look upon, stretched forth over their heads above.
Then I looked, and behold, in the firmament that was over the head of the cherubim there appeared above them as it were a sapphire stone, as the appearance of the likeness of a throne.
and before the throne, as it were a sea of glass like unto crystal; and in the midst of the throne, and round about the throne, four living creatures full of eyes before and behind.
And above the firmament that was over their heads was the likeness of a throne, as the appearance of a sapphire stone; and upon the likeness of the throne was a likeness as the appearance of a man upon it above.
and he that sat {\i was} to look upon like a jasper stone and a sardius: and {\i there was} a rainbow round about the throne, like an emerald to look upon.
