Ezekiel 1:9-13

joining one unto another are their wings, they turn not round in their going, each straight forward they go.

As to the likeness of their faces, the face of a man, and the face of a lion, toward the right are to them four, and the face of an ox on the left are to them four, and the face of an eagle are to them four.

And their faces and their wings are separate from above, to each are two joining together, and two are covering their bodies.

And each straight forward they go, whither the spirit is to go, they go, they turn not round in their going.

As to the likeness of the living creatures, their appearances are as coals of fire — burning as the appearance of lamps; it is going up and down between the living creatures, and brightness is to the fire, and out of the fire is going forth lightning.
