As for the likeness of the living creatures, their appearance was like burning coals of fire, and like the appearance of lamps: it went up and down among the living creatures; and the fire was bright, and out of the fire went forth lightning.
And the living creatures ran and returned as the appearance of a flash of lightning.
Now as I beheld the living creatures, behold one wheel upon the earth by the living creatures, with his four faces.
The appearance of the wheels and their work was like unto the colour of a beryl: and they four had one likeness: and their appearance and their work was as it were a wheel in the middle of a wheel.
When they went, they went upon their four sides: and they turned not when they went.
