Again we have a picture of four men walking with their inoperative helicopters moving in several different ways as the breeze and the men's motions cause them to move slightly.
Notice that Ezekiel seems to be more impressed with the wings and their motion than with any other feature of what he witnessed.
13. 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.
Here he is describing their over-all appearance. We can assume that creatures that look like men but has a surface that resembles lights, coals and fire must be wearing suits with a brightly colored metallic surface. The modern anodized aluminium coatings glisten and sparkle with an effect like he describes. If these are space-suits, there is a good reason for making them gaudy. If they were worn in space while working on and around a ship, they should be as bright and eye-catching as possible, in the case the man became detached and floated away. He would be quite visible against the blackness of space.
14. And the living creatures ran and returned as the appearance of a flash of lightning.
This might mean that they moved swiftly, but more than likely it means that they sparkled and shined on all sides, and this was visible as they moved about.
This ends the description for a while. There are two later verses of description, but we will take this when we come to it. It is surprising that Ezekiel has organized his material so well. It reads like a scientific report. If he had headed the section that we just covered, "Description," we would not have been too surprised to find the following section headed, "Action":
15. Now as I beheld the living creatures, behold one wheel upon the earth by the living creatures, with his four faces.
If we read Ezekiel correctly and the creatures did have helicopter attachments on their backs, we can assume that one of them now started his helicopter, which would appear as a "wheel" to Ezekiel, and probably surprised him greatly.
