Upon their four sides - i. e. straight in the direction toward which their faces looked. Since the four quarters express all directions, the construction of the living creatures was such that they could move in each direction alike.

When they went, they went upon their four sides,.... On either of their crossing rings, as they were directed by the living creatures, at whose side they stood:

and they returned not when they went; they had no need to turn about when they were to go east, west, north, or south, as wheels usually do; but they turned upon the crossing ring, which was towards either of the four points. This denotes the perseverance of the churches, and the true members thereof, in faith and practice; they do not turn back, nor look back, but go right on, walking in the fear of the Lord, and in all his, ways and ordinances.

When they went, they went upon their four sides: and they turned not when they went.

1:17 They - The wheels. Four sides - The wheels being supposed round every way as a globe, by an exact framing of two wheels one in the other; the four semi - circles which are in two whole wheels, may be well taken for these four sides on which these wheels move, and such a wheel will readily be turned to all points of the compass. Returned not - They returned not 'till they came to their journey's end; nothing could divert them, or put them out of their course. So firm and sure are the methods, so unalterable and constant the purposes of God, and so invariable the obedience and observance of holy angels. So subject to the sovereign will of God are all second causes.

17. went upon their four sides-Those faces or sides of the four wheels moved which answered to the direction in which the cherubim desired to move; while the transverse circles in each of the four composite wheels remained suspended from the ground, so as not to impede the movements of the others.

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.
