13As for the likeness of the living creatures, their appearance was like burning coals of fire, like the appearance of torches: [the fire] went up and down among the living creatures; and the fire was bright, and out of the fire went forth lightning.
14And the living creatures ran and returned as the appearance of a flash of lightning.
15Now as I beheld the living creatures, behold, one wheel upon the earth beside the living creatures, for each of the four faces thereof.
16The appearance of the wheels and their work was like unto a beryl: and they four had one likeness; and their appearance and their work was as it were a wheel within a wheel.
17When they went, they went in their four directions: they turned not when they went.
18As for their rims, they were high and dreadful; and they four had their rims full of eyes round about.
19And when the living creatures went, the wheels went beside them; and when the living creatures were lifted up from the earth, the wheels were lifted up.
