Now as I beheld the living creatures, behold one wheel upon the earth by the living creatures, with his four faces.

Wesley's Notes

1:15 Living creatures - By each of the living creatures stood one wheel, so that they were four in number, according to the number of living creatures. Four faces - By this it appears, each wheel had its four faces. While he was contemplating the glory of the former vision, this other was presented to him: wherein the dispensations of providence are compared to the wheels of a machine, which all contribute to the regular motion of it. Providence orders, changes: sometimes one spoke of the wheel is uppermost, sometimes another. But the motion of the wheel on its own axle - tree, is still regular and steady. And the wheel is said to be by the living creatures, who attend to direct its motion. For all inferior creatures are, and move, and act, as the Creator, by the ministration of angels directs and influences them: visible effects are managed and governed by invisible causes.

Jamieson-Fausset-Brown Bible Commentary

15. one wheel-The "dreadful height" of the wheel (Eze 1:18) indicates the gigantic, terrible energy of the complicated revolutions of God's providence, bringing about His purposes with unerring certainty. One wheel appeared traversely within another, so that the movement might be without turning, whithersoever the living creatures might advance (Eze 1:17). Thus each wheel was composed of two circles cutting one another at right angles, "one" only of which appeared to touch the ground ("upon the earth"), according to the direction the cherubim desired to move in.

with his four faces-rather, "according to its four faces" or sides; as there was a side or direction to each of the four creatures, so there was a wheel for each of the sides [Fairbairn]. The four sides or semicircles of each composite wheel pointed, as the four faces of each of the living creatures, to the four quarters of heaven. Havernick refers "his" or "its" to the wheels. The cherubim and their wings and wheels stood in contrast to the symbolical figures, somewhat similar, then existing in Chaldea, and found in the remains of Assyria. The latter, though derived from the original revelation by tradition, came by corruption to symbolize the astronomical zodiac, or the sun and celestial sphere, by a circle with wings or irradiations. But Ezekiel's cherubim rise above natural objects, the gods of the heathen, to the representation of the one true God, who made and continually upholds them.

Matthew Henry's Concise Commentary

1:15-25 Providence, represented by the wheels, produces changes. Sometimes one spoke of the wheel is uppermost, sometimes another; but the motion of the wheel on its own axletree is regular and steady. We need not despond in adversity; the wheels are turning round and will raise us in due time, while those who presume in prosperity know not how soon they may be cast down. The wheel is near the living creatures; the angels are employed as ministers of God's providence. The spirit of the living creatures was in the wheels; the same wisdom, power, and holiness of God, that guide and govern the angels, by them order all events in this lower world. The wheel had four faces, denoting that the providence of God exerts itself in all parts. Look every way upon the wheel of providence, it has a face toward you. Their appearance and work were as a wheel in the middle of a wheel. The disposals of Providence seem to us dark, perplexed, and unaccountable, yet are all wisely ordered for the best. The motion of these wheels was steady, regular, and constant. They went as the Spirit directed, therefore returned not. We should not have to undo that by repentance which we have done amiss, if we followed the guidance of the Spirit. The rings, or rims of the wheels were so vast, that when put in motion the prophet was afraid to look upon them. The consideration of the height and depth of God's counsel should awe us. They were full of eyes round about. The motions of Providence are all directed by infinite Wisdom. All events are determined by the eyes of the Lord, which are in every place beholding the evil and the good; for there is no such thing as chance or fortune. The firmament above was a crystal, glorious, but terribly so. That which we take to be a dark cloud, is to God clear as crystal, through which he looks upon all the inhabitants of the earth. When the angels had roused a careless world, they let down their wings, that God's voice might be plainly heard. The voice of Providence is to open men's ears to the voice of the word. Sounds on earth should awaken our attention to the voice from heaven; for how shall we escape, if we turn away from Him that speaks from thence.
