Ezekiel 1:11-14

11Thus were their faces: and their wings were stretched upward; two wings of every one were joined one to another, and two covered their bodies.1 12And they went every one straight forward: wherever the spirit was to go, they went; and they turned not when they went. 13As for the likeness of the living beings, their appearance was like burning coals of fire, and like the appearance of lamps: it went up and down among the living beings; and the fire was bright, and out of the fire went forth lightning. 14And the living beings ran and returned as the appearance of a flash of lightning.
