Ezekiel 1:22

And there came a sound from above the expanse that was over their heads; whenever they stood still, they dropped their wings.

Now above the expanse that was over their heads there was something in the likeness of a throne, like sapphire stone in appearance; and upon the likeness of the throne, high up, was the likeness of one with the appearance of a man.

Then I looked, and behold, in the expanse that was over the heads of the cherubim something like a sapphire stone, in appearance in the likeness of a throne, appeared above them.

These are the living creatures that I saw beneath the God of Israel by the river Chebar; so I knew that they were cherubim.

And it was like the appearance of the vision which I saw, like the vision which I saw when He came to bring the city to ruin. And the visions were like the vision which I saw by the river Chebar; and I fell on my face.

And before the throne there was something like a sea of glass, like crystal. And in the center and around the throne, four living creatures full of eyes in front and behind.

The Vision of the Glory of Yahweh
