Ezekiel 1:18

Their rings; the circumference of the wheels, the whole compass of the wheels, or the fellows (as a carter calls the whole roundle of his wheels). They were so high; the two strakes, the thickness of hob and felloes, give us the height of a wheel from the earth on which it stands; that they were dreadful; their very height impressed a fear on the beholder, but if we may suppose one near these wheels which so readily changed course, so easily overbearing all that none could turn them aside, (which might possibly be the prophet's case in this vision,) it would increase the terror. Their rings, the whole circumference or circle of these wheels, were full of eyes: this added to the dreadfulness of their appearance: so unusual and supernatural a sight could not but affect the prophet, who in so mighty a wheel might expect multitudes of nails, but instead thereof discovers as great a multitude of eyes. One eye seen, or imagined to be seen, suddenly, and in the dark, hath amazed many a one, how much more so many as would fill up the circumference of these wheels! for they were round about. Round about them four; every one of the four wheels were thus filled with eyes. Now this is too narrowly confined by some interpreters, who would have the greatness and policy of the Chaldean set out hereby; whereas the wheels, their motion, their height and eyes, signify the height, unsearchableness, wisdom, and vigilance of the Divine providence, in governing the affairs of the world and the church.
