The Divine deliverance is set forth under the familiar image of the coming of God in a tempest. Before it bursts, and simultaneous with the prayer, the "earth rocks and quivers," the sunless "pillars of the hills reel and rock to and fro," as if conscious of the gathering wrath which begins to flame far off in the highest heavens. There has been no forth-putting yet of the Divine power. It is but accumulating its fiery energy, and already the solid framework of the world trembles, anticipating the coming crash. The firmest things shake, the loftiest bow before His wrath. "There went up smoke out of his nostrils, and fire out of his mouth devoured; coals were kindled by it." This kindling anger, expressed by these tremendous metaphors, is conceived of as the preparation in "His temple" for the earthly manifestation of delivering vengeance. It is like some distant thunder-cloud which grows on the horizon into ominous blackness, and seems to be filling its ashen-coloured depths with store of lightnings. Then the piled-up terror begins to move, and, drawing nearer, pours out an avalanche of gloom seamed with fire. First the storm-cloud descends, hanging lower and lower in the sky. And whose foot is that which is planted upon its heavy mass, thick and frowning enough to be the veil of God?
"He bowed the heavens, and came down,
And blackness of cloud was under His feet."
Then the sudden rush of wind which heralds the lightning breaks the awful silence:—
And He rode upon a cherub, and did fly,
Yea, He swept along upon the wings of the wind.
The cherubs bear, as in a chariot, the throned God, and the swift pinions of the storm bear the cherubs. But He that sits upon the throne, above material forces and the highest creatures, is unseen. The psalmist's imagination stops at its base, nor dares to gaze into that light above; and the silence is more impressive than all words. Instead of pagan attempts at a likeness of God, we have next painted, with equal descriptive accuracy, poetic force, and theological truth, the pitchy blackness which hides Him. In the gloom of its depths He makes His "secret place" His "tent." It is "darkness of waters," that is, darkness from which streams out the thunder-rain; it is "thick clouds of the skies;" or perhaps the expression should be rendered, "heavy masses of clouds." Then comes the crash of the tempest. The brightness that lies closer around Him, and lives in the heart of the blackness, flames forth, parting the thick clouds—and through the awful rent hail and coals of fire are flung down on the trembling earth. The grand description may be rendered in two ways: either that adopted in our version, "At the brightness that was before Him His thick clouds passed—hailstones and coals of fire;" or, "Through His thick clouds there passed hailstones and coals of fire." The former of these is the more dramatic; the broken construction expresses more vividly the fierce suddenness of the lightning blaze and of the down-rush of the hail, and is confirmed by the repetition of the same words in the same construction in the next verse. That verse describes another burst of the tempest—the deep roll of the thunder along the skies is the voice of Jehovah, and again the lightning tears through the clouds, and the hail streams down. With what profound truth all this destructive power is represented as coming from the brightness of God—that "glory" which in its own nature is light, but in its contact with finite and sinful creatures must needs become darkness, rent asunder by lightning! What lessons as to the root and the essential nature of all punitive acts of God cluster round such words! and how calm and blessed the faith which can pierce even the thickest mass "that veileth Love!"—to see the light at the centre, even though the circumference be brooding thunder-clouds torn by sudden fires. Then comes the purpose of all this apocalypse of Divine magnificence. The fiery arrows scatter the psalmist's enemies. The waters in which he had well nigh drowned are dried up before the hot breath of His anger. "That dread voice" speaks "which shrinks their streams." And amid the blaze of tempest, the rocking earth, and the failing floods, His arm is thrust forth from above, and draws His servant from many waters. As one in later times, "he was afraid, and beginning to sink, he cried, saying, Lord, save me; and immediately He stretched forth His hand and caught him."
A calmer tone follows, as the psalmist recounts without metaphor his deliverance, and reiterates the same assertion of his innocence which we have already found so frequently in the previous psalms (vers. 17-24). Rising from his personal experience to the broad and lofty thoughts of God which that experience had taught him, as it does all who prize life chiefly as a means of knowing Him, he proclaims the solemn truth, that in the exercise of a righteous retribution, and by the very necessity of our moral nature, God appears to man what man is to God: loving to the loving, upright to the upright, pure to the pure, and froward to the froward. Our thoughts of God are shaped by our moral character; the capacity of perceiving depends on sympathy. "Unless the eye were light, how could it see the sun?" The self-revelation of God in His providence, of which only the psalm speaks, is modified according to our moral character, being full of love to those who love, being harsh and antagonistic to those who set themselves in opposition to it. There is a higher law of grace, whereby the sinfulness of man but draws forth the tenderness of a father's pardoning pity; and the brightest revelation of His love is made to froward prodigals. But that is not in the psalmist's view here, nor does it interfere with the law of retribution in its own sphere.
The purely personal tone is again resumed, and continued unbroken to the close. In the former portion David was passive, except for the voice of prayer, and God's arm alone was his deliverance. In the latter half he is active, the conquering king, whose arm is strengthened for victory by God. This difference may possibly suggest the reference of the former half to the Sauline persecution, when, as we have seen, the exile ever shrunk from avenging himself; and of the latter to the early years of his monarchy, which, as we shall see, were characterized by much successful military activity; and if so, the date of the psalm would most naturally be taken to be the close of his victorious campaigns, when "the Lord had given him rest from all his enemies round about" (2 Sam. vii. 1). Be that as it may, the latter portion of the psalm shows us the soldier king tracing all his past victories to God alone, and building upon them the confidence of a world-wide dominion. The point at which memory passes into hope is difficult to determine, and great variety of opinion prevails on the matter among commentators. It is perhaps best to follow many of the older versions, and the valuable exposition of Hupfeld, in regarding the whole section from ver. 37 of our translation as the expression of the trust which past experience had wrought. We shall then have two periods in the second half of the psalm—the past victories won by God's help (vers. 31-36), the coming triumphs of which these are the pledge (vers. 37-end).
In the former there shine out not only David's habitual consciousness of dependence on and aid from God, but also a very striking picture of his physical qualifications for a military leader. He is girded with bodily strength, swift and sure of foot like a deer, able to scale the crags where his foes fortified themselves like the wild antelopes he had so often seen bounding among the dizzy ledges of the cliffs in the wilderness; his hands are trained for war, and his sinewy arms can bend the great bow of brass. But these capacities are gifts, and not they, but their Giver, have made him victorious. Looking back upon all his past, this is its summing up:—
"Thou hast also given me the shield of Thy salvation,
And Thy right hand hath holden me up,
And Thy lowliness hath made me great."
