15Now as I saw the living creatures, behold, one wheel on the earth beside the living creatures, for each of the four faces of it. 16The appearance of the wheels and their work was like a beryl: and they four had one likeness; and their appearance and their work was as it were a wheel within a wheel. 17When they went, they went in their four directions: they didn`t turn when they went. 18As for their rims, they were high and dreadful; and they four had their rims full of eyes round about. 19When the living creatures went, the wheels went beside them; and when the living creatures were lifted up from the earth, the wheels were lifted up.
