Ezekiel 1:15-25 NLT
As I looked at these beings, I saw four wheels touching the ground beside them, one wheel belonging to each. The wheels sparkled as if made of beryl. All four wheels looked alike and were made the same; each wheel had a second wheel turning crosswise within it. The beings could move in any of the four directions they faced, without turning as they moved. The rims of the four wheels were tall and frightening, and they were covered with eyes all around.
When the living beings moved, the wheels moved with them. When they flew upward, the wheels went up, too. The spirit of the living beings was in the wheels. So wherever the spirit went, the wheels and the living beings also went. When the beings moved, the wheels moved. When the beings stopped, the wheels stopped. When the beings flew upward, the wheels rose up, for the spirit of the living beings was in the wheels.
Spread out above them was a surface like the sky, glittering like crystal. Beneath this surface the wings of each living being stretched out to touch the others’ wings, and each had two wings covering its body. As they flew, their wings sounded to me like waves crashing against the shore or like the voice of the Almighty or like the shouting of a mighty army. When they stopped, they let down their wings. As they stood with wings lowered, a voice spoke from beyond the crystal surface above them.
