Ezekiel 1:22-26
22 Spread out above the heads of the living creatures was what looked like an expanse, sparkling like ice, and awesome.
23 Under the expanse their wings were stretched out one toward the other, and each had two wings covering its body.
24 When the creatures moved, I heard the sound of their wings, like the roar of rushing waters, like the voice of the Almighty, like the tumult of an army. When they stood still, they lowered their wings.
25 Then there came a voice from above the expanse over their heads as they stood with lowered wings.
26 Above the expanse over their heads was what looked like a throne of sapphire, and high above on the throne was a figure like that of a man.
