Ezekiel 1:14 ASV

¹²  And they went every one straight forward: whither the spirit was to go, they went; they turned not when they went.

¹³  As 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.

¹⁴  And the living creatures ran and returned as the appearance of a flash of lightning.

¹⁵  Now as I beheld the living creatures, behold, one wheel upon the earth beside the living creatures, for each of the four faces thereof.

¹⁶  The 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.
