13 As for the form of the living creatures, their appearance was like burning coals of fire, resembling torches moving between the living creatures. There was brightness to the fire, and lightning went forth from the fire.
14 The living creatures were running back and forth like flashes of lightning.
15 As I looked at the living creatures, behold, one wheel was on the ground next to each of the four-faced creatures.
16 The appearance and structure of the wheels was like the gleaming of beryl. The four had the same likeness, their appearance and their structure seemed to be a wheel within a wheel.
17 When they went, they went in any of their four directions without pivoting as they went.
18 Their rims were high and awesome—all four rims were full of eyes all around.
19 When the living creatures went, the wheels went beside them. When the living creatures rose from the earth, the wheels rose.
