Ezekiel 1:12 explains that the spirit directs the living creatures' movement — the same spirit coordinates the wheels here.

Ezekiel 1:20 states the spirit of the living creatures is in the wheels — the identical principle behind their joint motion here.

Ezekiel 1:21 describes the same synchronized motion because the spirit is in the wheels — exactly what drives them here.

Ezekiel 3:13 adds the sound of wheels and wings to the coordinated motion — the auditory counterpart to the spirit-led movement here.
