Ezekiel 1:21-23 New American Standard Bible (NASB)
21 Whenever those went, these went; and whenever those stood still, these stood still. And whenever those rose from the earth, the wheels rose close beside them; for the spirit of the living [a]beings was in the wheels.
Vision of Divine Glory
22 Now over the heads of the living [b]beings there was something like an expanse, like the awesome gleam of [c]crystal, spread out over their heads. 23 Under the expanse their wings were stretched out straight, one toward the other; each one also had two wings covering its body on the one side and on the other.
