Ezekiel 1:6-9

And every one had four faces, and every one had four wings. And their feet were straight feet; and the sole of their feet was like the sole of a calf's foot: and they sparkled like the colour of burnished brass. And they had the hands of a man under their wings on their four sides; and they four had their faces and their wings. Their wings were joined one to another; they turned not when they went; they went every one straight forward.
