Ezekiel 1:14 WEB

¹²  They went everyone straight forward: where the spirit was to go, they went; they didn't turn 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  The living creatures ran and returned as the appearance of a flash of lightning.

¹⁵  Now as I saw the living creatures, behold, one wheel on the earth beside the living creatures, for each of the four faces of it.

¹⁶  The appearance of the wheels and their work was like a beryl: and they four had one likeness; and their appearance and their work was as it were a wheel within a wheel.
