And the Lord said, Behold, there is a place by me This description may illdeed appear puerile, but it is well adapted to our imperfection; nor will any despise it who is duly conscious of his own imbecility and ignorance. There seems to be a contradiction between these two things, that the beauty of God should be shewn to Moses, and still that the sight of Him should be refused. This difficulty is here solved, for Moses was to see God only from behind. It is a similitude taken from men, whom we only partially recognise, if their face be turned away; for clear recognition is only obtained by seeing the face and countenance. The fissure or hole in the rock was like a narrow and oblique window, which so far admits the sun's rays as that one, who is shut up in a deep and obscure place, may receive some advantage from the light, yet never see the sun itself nor enjoy its brightness. Thus we, imprisoned as it were in our bodies, cannot behold God's glory freely and directly; but He illuminates us obliquely, so that at least we see Him from behind. I do not speak of all, but of the most perfect amongst us, such as Moses was, who, although he obtained the extraordinary privilege which is here recorded, yet could not endure God's glory through the infirmity of his flesh; and therefore the hand of God was interposed, so that he should only see Him in part. By God's hand is meant the darkness wherewith He was covered, lest the eyes of Moses should be stretched in curiosity to see further than was lawful. Some [1] refer "my back parts" to the fullless of time, when Christ was manifested in the flesh, as if it were said, Thou shalt not see me until clothed in human nature; this is a subtle speculation, but by no means sound, nay, altogether wide of the genuine meaning.

1 - "Tertullian referreth these backer or latter parts to the latter times of the Messiah: My glory which thou desirest to see, shall be revealed in the latter times." -- Willet in loco. Owen's exposition of this passage is worthy of quotation: "The face of God, or the gracious majesty of his Being, his essential glory, is not to be seen of any in this life; we cannot see him as he is. But the glorious manifestation of himself we may behold and contemplate. This we may see as the back parts of God; that shadow of his excellencies which he casteth forth in the passing by us in his works and dispensations. This Moses shall see. And wherein did it consist? Why, in the revelation, and declaration of this name of God. Exodus 34:6, 7. To be known by this name, to be honored, feared, believed, as that declares him, is the great glory of God." -- Owen's Expos. of Psalm 130. (Edin., edit. 1851, vol. 6, p. 481.)

Behold, there is a place by me - There seems to be a reference here to a well-known place on the mount where God was accustomed to meet with Moses. This was a rock; and it appears there was a cleft or cave in it, in which Moses was to stand while the Divine Majesty was pleased to show him all that human nature was capable of bearing: but this appears to have referred more to the counsels of his mercy and goodness, relative to his purpose of redeeming the human race, than to any visible appearance of the Divine Majesty itself. See Clarke on Exodus 33:18 (note).
1. The conclusion of this chapter is very obscure: we can scarcely pretend to say, in any precise manner, what it means; and it is very probable that the whole concerned Moses alone. He was in great perplexity and doubt; he was afraid that God was about to abandon this people; and he well knew that if he did so, their destruction must be the consequence. He had received general directions to decamp, and lead the people towards the promised land; but this was accompanied with a threat that Jehovah would not go with them. The prospect that was before him was exceedingly gloomy and discouraging; and it was rendered the more so because God predicted their persevering stiffneckedness, and gave this as one reason why he would not go up among them, for their provocations would be so great and so frequent that his justice would be so provoked as to break through in a moment and consume them. Moses, well knowing that God must have some great and important designs in delivering them and bringing them thus far, earnestly entreated him to give him some discovery of it, that his own mind might be satisfied. God mercifully condescends to meet his wishes in such a way as no doubt gave him full satisfaction; but as this referred to himself alone the circumstances are not related, as probably they could be of no farther use to us than the mere gratifying of a principle of curiosity.
2. On some occasions to be kept in the dark is as instructive as to be brought into the light. In many cases those words of the prophet are strictly applicable. Verily, thou art a God, who Hidest Thyself, O God of Israel, the Savior! One point we see here very plainly, that while the people continued obstinate and rebellious, that presence of God by which his approbation was signified could not be manifested among them; and yet, without his presence to guide, protect, and provide for them, they could neither go up nor be saved. This presence is promised, and on the fulfillment of the promise the safety of Israel depended. The Church of God is often now in such a state that the approbation of God cannot be manifested in it; and yet if his presence were wholly withdrawn, truth would fall in the streets, equity go backward, and the Church must become extinct. How have the seeds of light and life been preserved during the long, dark, and cold periods when error was triumphant, and the pure worship of God adulterated by the impurities of idolatry and the thick darkness of superstition, by the presence of his endless mercy, preserving his own truth in circumstances in which he could not show his approbation! He was with the Church in the wilderness, and preserved the living oracles, kept alive the heavenly seeds, and is now showing forth the glory of those designs which before he concealed from mankind. He cannot err because he is infinitely wise; he can do nothing that is unkind, because he delighteth in mercy. We, as yet, see only through a glass darkly; by and by we shall see face to face. The Lord's presence is with his people; and those who trust in him have confident rest in his mercy.

And the LORD said, Behold, [there is] a place by (m) me, and thou shalt stand upon a rock:
(m) In mount Horeb.

And the Lord said, behold, there is a place by me,.... Near him, not in or by the tabernacle, where it may be the pillar of cloud now was, as it had been, Exodus 33:9 but upon the rock, where it had been for many days, and near to which there was a fit place for Moses to be in, and have that view of the goodness and glory of God he would favour him with:
and thou shall stand upon a rock; in Horeb, typical of Christ the rock, the rock of Israel, and the rock of ages, the rock of refuge, salvation, and strength; comparable to one for shelter, solidity, firmness, strength, and duration; and happy are they who stand upon this rock; they are safe and secure, they stand on high, and have noble prospects of the perfections of God, and of the riches of his grace and goodness, see Psalm 50:2.
