Psalms 18:7

Then the earth shook and trembled - "In this and the following verses David describes, by the sublimest expressions and grandest terms, the majesty of God, and the awful manner in which he came to his assistance. The representation of the storm in these verses must be allowed by all skillful and impartial judges to be truly sublime and noble, and in the genuine spirit of poetry. The majesty of God, and the manner in which he is represented as coming to the aid of his favourite king, surrounded with all the powers of nature as his attendants and ministers, and arming (as it were) heaven and earth to fight his battles, and execute his vengeance, is described in the loftiest and most striking terms. The shaking of the earth; the trembling of the mountains and pillars of heaven; the smoke that drove out of his nostrils; the flames of devouring fire that flashed from his mouth; the heavens bending down to convey him to the battle; his riding upon a cherub, and rapidly flying on the wings of a whirlwind; his concealing his majesty in the thick clouds of heaven; the bursting of the lightnings from the horrid darkness; the uttering of his voice in peals of thunder; the storm of fiery hail; the melting of the heavens, and their dissolving into floods of tempestuous rain; the cleaving of the earth, and disclosing of the bottom of the hills, and the subterraneous channels or torrents of water, by the very breath of the nostrils of the Almighty; are all of them circumstances which create admiration, excite a kind of horror, and exceed every thing of this nature that is to be found in any of the remains of heathen antiquity. See Longinus on the Sublime, sec. 9, and Hesiod's description of Jupiter fighting against the Titans, which is one of the grandest things in all pagan antiquity; though upon comparison it will be found infinitely short of this description of the psalmist's; throughout the whole of which God is represented as a mighty warrior going forth to fight the battles of David, and highly incensed at the opposition his enemies made to his power and authority.

"When he descended to the engagement the very heavens bowed down to render his descent more awful, his military tent was substantial darkness; the voice of his thunder was the warlike alarm which sounded to the battle; the chariot in which he rode was the thick clouds of heaven, conducted by cherubs, and carried on by the irresistible force and rapid wings of an impetuous tempest; and the darts and weapons he employed were thunderbolts, lightnings, fiery hail, deluging rains, and stormy winds!

"No wonder that when God thus arose, all his enemies should be scattered, and those who hated him should flee before him.

"It does not appear from any part of David's history that there was any such storm as is here described, which proved destructive to his enemies, and salutary to himself. There might, indeed, have been such a one, though there is no particular mention of it: unless it may be thought that something of this nature is intimated in the account given of David's second battle with the Philistines, 2 Samuel 5:23, 2 Samuel 5:24. It is undoubted, however, that the storm is represented as real; though David, in describing it, has heightened and embellished it with all the ornaments of poetry. See Chandler, Delaney, and Lowth's ninth Prelection.

Then the earth shook and trembled - The description which follows here is one of the most sublime that is to be found in any language. It is taken from the fury of the storm and tempest, when all the elements are in commotion; when God seems to go forth in the greatness of his majesty and the terror of his power, to prostrate everything before him. We are not to regard this as descriptive of anything which literally occurred, but rather as expressive of the fact of the divine interposition, as if he thus came forth in the greatness of his power. There is no improbability indeed in supposing that in some of the dangerous periods of David's life, when surrounded by enemies, or even when in the midst of a battle, a furious tempest may have occurred that seemed to be a special divine interposition in his behalf, but we have no distinct record of such an event, and it is not necessary to suppose that such an event occurred in order to a correct understanding of the passage. All that is needful is to regard this as a representation of the mighty interposition of God; to suppose that his intervention was as direct, as manifest, and as sublime, as if he had thus interposed. There are frequent references in the Scriptures to such storms and tempests as illustrative of the majesty, the power, and the glory of God, and of the manner in which he interposes on behalf of his people. See Psalm 144:5-7; Psalm 46:6-8; Psalm 29:1-11; Job 37:21-24; Job 38:1; Nahum 1:3; and particularly Habakkuk 3:3-16. The description in Habakkuk strongly resembles the passage before us, and both were drawn doubtless from an actual observation of the fury of a tempest.

The foundations also of the hills moved - The mountains seemed to rock on their foundations. In the corresponding place in 2 Samuel 22:8 the expression is, "The foundations of heaven moved and shook;" that is, that on which the heavens seem to rest was agitated. Many suppose that the expression refers to the mountains as if they bore up the heavens; but DeWette more properly supposes that the reference is to the heavens as a building or an edifice resting on foundations. Why the change was made in revising the psalm from the "foundations of the heavens" to the "foundations of the hills," it is impossible now to determine.

Because he was wroth - literally," Because it was inflamed (or enkindled) to him;" that is, because he was angry. Anger is often compared to a raging flame, because it seems to consume everything before it. Hence, we speak of it as "heated," as "burning." So we say of one that he is "inflamed by passion." The expression here is sublime in the highest degree. God seemed to be angry, and hence, he came forth in this awful manner, and the very earth trembled before him.

18:7 Then - Then God appeared on my behalf in a glorious manner, to the terror and confusion of all mine enemies, which is here compared to an earthquake.
