12 And each went straight forward; wherever the spirit went they went, and they did not turn as they went.
13 As for the likeness of the living creatures, their appearance was like burning coals of fire, like the appearance of torches. It was moving to and fro between the living creatures, and the fire was very bright and lightning was going out from the fire.
14 And the living creatures were speeding to and fro like the appearance of lightning.
15 And I saw the living creatures, and look! A wheel was on the earth beside each of the living creatures that had four faces.
16 The appearance of the wheels and their construction was like the appearance of beryl, and they all looked alike, and their appearance and their construction was like a wheel within a wheel.
17 When they moved, they went toward their four sides; they did not veer at all as they went.
18 And their rims were high and awesome, and all four of their rims were full of eyes all around.
