Ezekiel 1:9-13

their wings are joining to one another, they do not turn around in their going, they each go straight forward.

As for the likeness of their faces, each had the face of a man, and toward the right the four had the face of a lion, and on the left the four had the face of an ox, and the four had the face of an eagle.

And their faces and their wings dividing from above, of each are two joining together, and two are covering their bodies.

And they each go straight forward, to where the Spirit is to go, they go, they do not turn around in their going.

As for 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 lightning is going forth out of the fire.
