Ezekiel 1:21-23 Holman Christian Standard Bible (HCSB)
21 When the creatures moved, the wheels moved; when the creatures stood still, the wheels stood still; and when the creatures rose from the earth, the wheels rose alongside them, for the spirit of the living creatures was in the wheels.
22 The shape of an expanse, with a gleam like awe-inspiring crystal, was spread out over the heads of the living creatures. 23 And under the expanse their wings extended one toward another. Each of them also had two wings covering their bodies.
