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.

The appearance of the living creatures was like burning coals of fire or like torches. Fire moved back and forth among the creatures; it was bright, and lightning flashed out of it.
