Ezequiel 1:13

Cuanto á la semejanza de los animales, su parecer era como de carbones de fuego encendidos, como parecer de hachones encendidos: discurría entre los animales; y el fuego resplandecía, y del fuego salían relámpagos.

As for the likeness of the living creatures, their appearance was like burning coals of fire, and like the appearance of lamps: it went up and down among the living creatures; and the fire was bright, and out of the fire went forth lightning.
