Ezekiel 1:11-15

Such were their faces. Their wings were spread out above; each had two touching another being, and two covering their bodies.

And each went straight forward; wherever the spirit was about to go, they would go, without turning as they went.

In the midst of the living beings there was something that looked like burning coals of fire, like torches moving among the living beings. The fire was bright, and lightning was flashing from the fire.

And the living beings ran back and forth like bolts of lightning.

Now as I looked at the living beings, behold, there was one wheel on the ground beside the living beings, for each of the four of them.
