15 And I looked on the living creatures, and, behold, there was one wheel upon the earth close by the living creatures, by their four front faces.
16 The appearance of the wheels and their work was like the color of a chrysolite; and all four had one likeness: and their appearance and their work was as though it were a wheel in the middle of a wheel.
17 Toward their four sides they went in their going: they turned not round in their going.
