Ezekiel 1:21-23 New Life Version (NLV)
21 When the living beings moved, they moved. When the beings stood still, they stood still. And when the beings rose up from the earth, the wheels rose close beside them. For the spirit of the living beings was in the wheels.
22 Over the heads of the living beings there was something that looked like the sky. It shined like crystal and spread over their heads. 23 Under this covering their wings were spread out straight, one toward the other. Each one also had two wings covering their bodies on one side and on the other.
