Ezekiel 1:21-23 Revised Standard Version Catholic Edition (RSVCE)
21 When those went, these went; and when those stood, these stood; and when those 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 the likeness of a firmament, shining like crystal,[a] spread out above their heads. 23 And under the firmament their wings were stretched out straight, one toward another; and each creature had two wings covering its body.[b]
Ezekiel 1:21-23 New International Version (NIV)
21 When the creatures moved, they also moved; when the creatures stood still, they also stood still; and when the creatures rose from the ground, the wheels rose along with them, because the spirit of the living creatures was in the wheels.
22 Spread out above the heads of the living creatures was what looked something like a vault, sparkling like crystal, and awesome. 23 Under the vault their wings were stretched out one toward the other, and each had two wings covering its body.
