Ezekiel 1:13-15

Young's Literal Translation

¹³ As to the likeness of the living creatures, their appearances [are] as coals of fire -- burning as the appearance of lamps; it is going up and down between the living creatures, and brightness [is] to the fire, and out of the fire is going forth lightning.

¹⁴ And the living creatures are running, and turning back, as the appearance of the flash.

¹⁵ And I see the living creatures, and lo, one wheel [is] in the earth, near the living creatures, at its four faces.
