Ezekiel 10:9-14

And when I looked, behold the four wheels by the cherubims, one wheel by one cherub, and another wheel by another cherub: and the appearance of the wheels was as the colour of a beryl stone. And as for their appearances, they four had one likeness, as if a wheel had been in the midst of a wheel. When they went, they went upon their four sides; they turned not as they went, but to the place whither the head looked they followed it; they turned not as they went. And their whole body, and their backs, and their hands, and their wings, and the wheels, were full of eyes round about, even the wheels that they four had. As for the wheels, it was cried unto them in my hearing, O wheel. And every one had four faces: the first face was the face of a cherub, and the second face was the face of a man, and the third the face of a lion, and the fourth the face of an eagle.
