Ezekiel 1:20-22

Complete Jewish Bible

²⁰ Wherever the spirit was to go, they went, in the direction the spirit wanted to go. The wheels were lifted up next to them, because the spirit of the living creatures was in the wheels. ²¹ When [the living creatures] moved, [the wheels] moved; when the former stood still, the latter stood still; and when the former were lifted off the ground, the wheels were lifted up next to them; because the spirit of the living creatures was in the wheels.

²² Over the heads of the living creatures was what appeared to be a dome glittering like ice; it was awesome, spread out over their heads, above them.
