Ezekiel 1:11-14

11Thus were their faces. Their wings stretched upward; two wings of each one touched one another, and two covered their bodies.

12And each one went straight forward; they went wherever the spirit wanted to go, and they did not turn when they went.

13As for the likeness of the living creatures, their appearance was like burning coals of fire, like the appearance of torches going back and forth among the living creatures. The fire was bright, and out of the fire went lightning.

14And the living creatures ran back and forth, in appearance like a flash of lightning.
