Ezekiel 1:22

And the likeness over the heads of the living creatures was as a firmament, as the appearance of crystal, spread out over their wings above.

And the likeness of the firmament upon the heads of the living creature was as the colour of the terrible crystal, stretched forth over their heads above.

Over the head of the living creature there was the likeness of an expanse, like an awesome crystal to look at, stretched out over their heads above.
