Ezekiel 1:20

As for their rings, they were so high that they were dreadful; and their rings [were] full of eyes round about them four.

And when the living creatures went, the wheels went by them: and when the living creatures were lifted up from the earth, the wheels were lifted up.

When those went, [these] went; and when those stood, [these] stood; and when those were lifted up from the earth, the wheels were lifted up over against them: for the spirit of the living creature [was] in the wheels.

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.
