As our Lord was in the habit of asking for some confession, or demanding some small co-operation from those He was about to bless, so the smoking flax of Hebrew faith is tended: it is a promise, and not the actual relief, which calms them. There is a curious difference in the manner of the communications now made to the people. First of all the two brothers unite their energies to hush their outcries: “At evening ye shall know that Jehovah is your leader from Egypt, and in the morning ye shall behold His glory; and what are we, that ye murmur against us?” Then Moses affirms, with all the energy of his chieftainship, that in the evening they shall eat flesh, and in the morning bread to the full. Again he asks them “What are we?” and more sternly and directly charges them with murmuring against Jehovah. And this is a good example of the true meaning of his “meekness.” He is fiery enough, but not for his own greatness; rather because he feels his littleness, and that the offence is entirely against God, does he resent their conduct; absence of self-assertion is his “meekness,” and thus we read of it when Miriam and Aaron spake against him, declaring that they were commissioned as well as he (Num. xii. 3). Finally, when order was restored, and some mysterious manifestation was at hand, he resumed the solemn and formal usage of conveying his orders through his brother, and in cold, compact, impressive words, said unto Aaron, “Say unto all the congregation of the children of Israel, Come near before the Lord, for He hath heard your murmurings.” All this is very dignified and natural. And so is—what after ages could scarcely have invented—the impressive reticence of what follows. “They looked toward the wilderness, and behold, the glory of the Lord appeared in the cloud.”

Were they not then intended to “come near”? and was it as they turned their faces to draw nigh that the Vision revealed itself and stopped them? And what was the untold sight which they beheld? The narrative belongs to a primitive age; it is quite unlike the elaborate symbolisms of Ezekiel and Daniel, or even of Isaiah, but yet this undescribed, mystic and solitary glory is not less sublime than the train which covered the Temple-floor, while, hovering above it, reverent seraphim veiled their faces and their feet, or the terrible crystal and the wheels of dreadful height, or the throne of flame whence issued a fiery stream, and before which thousands of thousands and myriads of myriads stood (Isa. vi. 2; Ezek. i. 22, 18; Dan. vii. 9, 10). But the point to observe is that it is different, more primitive, an undefined and lonely vision of awe well fitted for the desert wilds and for the gaze of men whose hearts must not be misled by the likeness of anything in heaven or earth; the glory of the Lord appearing in the cloud (most probably, but not of necessity, the cloud which guided them), and in the direction whence they were so fain to turn away.
