13 Regarding the creatures’ forms: they looked like blazing coals, like torches. Fire darted about between the creatures and illuminated them, and lightning flashed from the fire.

15 As I looked at the creatures, suddenly there was a wheel on the earth corresponding to all four faces of the creatures.
16 The appearance and composition of the wheels were like sparkling topaz. There was one shape for all four of them, as if one wheel were inside another.
17 When they moved in any of the four directions, they moved without swerving.
18 Their rims were tall and terrifying, because all four of them were filled with eyes all around.
