Ezekiel 1:13 WEB

¹¹  Their faces and their wings were separate above; two [wings] of everyone were joined one to another, and two covered their bodies.

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.
