There are many echoes of this period of Engedi in the Psalms. Perhaps the most distinctly audible of these are to be found in the seventh psalm, which is all but universally recognised as David's, even Ewald concurring in the general consent. It is an irregular ode—for such is the meaning of Shiggaion in the title, and by its broken rhythms and abrupt transitions testifies to the emotion of its author. The occasion of it is said to be "the words of Cush the Benjamite." As this is a peculiar name for an Israelite, it has been supposed to be an allegorical designation for some historical person, expressive of his character. We might render it "the negro." The Jewish commentators have taken it to refer to Saul himself, but the bitter tone of the psalm, so unlike David's lingering forbearance to the man whom he never ceased to love, is against that supposition. Shimei the Benjamite, whose foul tongue cursed him in rabid rage, as he fled before Absalom, has also been thought of, but the points of correspondence with the earlier date are too numerous to make that reference tenable. It seems better to suppose that Cush "the black" was one of Saul's tribe, who had been conspicuous among the calumniators of whom we have seen David complaining to the king. And if so, there is no period in the Sauline persecution into which the psalm will fit so naturally as the present. Its main thoughts are precisely those which he poured out so passionately in his eager appeal when he and Saul stood face to face on the solitary hill side. They are couched in the higher strain of poetry indeed, but that is the only difference; whilst there are several verbal coincidences, and at least one reference to the story, which seem to fix the date with considerable certainty.
In it we see the psalmist's soul surging with the ground swell of strong emotion, which breaks into successive waves of varied feeling—first (vers. 1, 2) terror blended with trust, the enemy pictured, as so frequently in these early psalms, as a lion who tears the flesh and breaks the bones of his prey—and the refuge in God described by a graphic word very frequent also in the cotemporaneous psalms (xi. 1; lvii. 1, etc.). Then with a quick turn comes the passionate protestation of his innocence, in hurried words, broken by feeling, and indignantly turning away from the slanders which he will not speak of more definitely than calling them "this."
(3) Jehovah, my God! if I have done this—
If there be iniquity in my hands—
(4) If I have rewarded evil to him that was at peace with me—
Yea, I delivered him that without cause is mine enemy—
(5) May the enemy pursue my soul and capture it,
And trample down to the earth my life,
And my glory in the dust may he lay!
How remarkably all this agrees with his words to Saul, "There is neither evil nor transgression in my hand, ... yet thou huntest my soul to take it" (1 Sam. xxiv. 11); and how forcible becomes the singular reiteration in the narrative, of the phrase "my hand," which occurs six times in four verses. The peculiarly abrupt introduction in ver. 4 of the clause, "I delivered him that without cause is mine enemy," which completely dislocates the grammatical structure, is best accounted for by supposing that David's mind is still full of the temptation to stain his hands with Saul's blood, and is vividly conscious of the effort which he had had to make to overcome it. And the solemn invocation of destruction which he dares to address to Jehovah his God includes the familiar figure of himself as a fugitive before the hunters, which is found in the words already quoted, and which here as there stands in immediate connection with his assertion of clean hands.
Then follows, with another abrupt turn, a vehement cry to God to judge his cause; his own individual case melts into the thought of a world-wide judgment, which is painted with grand power with three or four broad rapid strokes.
(6) Awake for me—Thou hast commanded judgment.
(7) Let the assembly of the nations stand round Thee,
And above it return Thou up on high.
(8) Jehovah will judge the nations.
Judge me, O Jehovah, according to my righteousness and mine integrity in
me!
Each smaller act of God's judgment is connected with the final world-judgment, is a prophecy of it, is one in principle therewith; and He, who at the last will be known as the universal Judge of all, certainly cannot leave His servants' cause unredressed nor their cry unheard till then. The psalmist is led by his own history to realize more intensely that truth of a Divine manifestation for judicial purposes to the whole world, and his prophetic lip paints its solemnities as the surest pledge of his own deliverance. He sees the gathered nations standing hushed before the Judge, and the Victor God at the close of the solemn act ascending up on high where He was before, above the heads of the mighty crowd (Psalm lxviii. 19). In the faith of this vision, and because God will judge the nations, he invokes for himself the anticipation of that final triumph of good over evil, and asks to be dealt with according to his righteousness. Nothing but the most hopeless determination to find difficulties could make a difficulty of such words. David is not speaking of his whole character or life, but of his conduct in one specific matter, namely, in his relation to Saul. The righteous integrity which he calls God to vindicate is not general sinlessness nor inward conformity with the law of God, but his blamelessness in all his conduct to his gratuitous foe. His prayer that God would judge him is distinctly equivalent to his often repeated cry for deliverance, which should, as by a Divine arbitration, decide the debate between Saul and him. The whole passage in the psalm, with all its lyrical abruptness and lofty imagery, is the expression of the very same thought which we find so prominent in his words to Saul, already quoted, concerning God's judging between them and delivering David out of Saul's hand. The parallel is instructive, not only as the prose rendering of the poetry in the psalm, explaining it beyond the possibility of misunderstanding, but also as strongly confirmatory of the date which we have assigned to the latter. It is so improbable as to be almost inconceivable that the abrupt disconnected themes of the psalm should echo so precisely the whole of the arguments used in the remonstrance of the historical books, and should besides present verbal resemblances and historical allusions to these, unless it be of the same period, and therefore an inlet into the mind of the fugitive as he lurked among the rugged cliffs by "the fountain of the wild goat."
In that aspect the remainder of the psalm is very striking and significant. We have two main thoughts in it—that of God as punishing evil in this life, and that of the self-destruction inherent in all sin; and these are expressed with such extraordinary energy as to attest at once the profound emotion of the psalmist, and his familiarity with such ideas during his days of persecution. It is noticeable, too, that the language is carefully divested of all personal reference; he has risen to the contemplation of a great law of the Divine government, and at that elevation the enemies whose calumnies and cruelties had driven him to God fade into insignificance.
With what magnificent boldness he paints God the Judge arraying Himself in His armour of destruction!
