Ezekiel 1:13 ASV

¹¹  And their faces and their wings were separate above; two 'wings' of every one were joined one to another, and two covered their bodies.

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.
