Ezekiel 1:20-22

New Revised Standard Version Catholic Edition

²⁰ Wherever the spirit would go, they went, and the wheels rose along with them; for the spirit of the living creatures was in the wheels. ²¹ When they moved, the others moved; when they stopped, the others stopped; and when they rose from the earth, the wheels rose along with them; for the spirit of the living creatures was in the wheels.

²² Over the heads of the living creatures there was something like a dome, shining like crystal,^[a] spread out above their heads.
