Ezekiel 1:16

16. One wheel was beside each living creature. Each wheel flashed like a precious stone.

A wheel in the middle of a wheel Each wheel seemed to be composed of two wheels cutting each other at right angles. Thus each wheel was always facing every point of the compass, and in whatever direction the chariot moved four wheels were running. They, like the chariot, could, without turning, revolve in any direction the spirit indicated.

Wesley conceived these wheels as globes or spheres of light, having tires of exceptional brightness. Wheels fitly symbolize “the height, unsearchableness, wisdom, and vigilance of the divine power.”
