Ezekiel 1:22-25

Now, over the heads of the living creatures was something like a dome that sparkled like ice and was frightening. And under the dome the wings of the living creatures were stretched out straight toward one another. Each living creature also had two wings covering its body. I heard the sound of their wings, like the roaring sound of the sea, as they moved. It was like the voice of God Almighty, a roaring sound like a noisy army. When the living creatures stopped, they lowered their wings. A voice came from above the dome over the heads of the living creatures. When the living creatures stopped, they lowered their wings.
