O Jehovah my God Here David, to induce God to show him favour, protests that he is molested unjustly, and without being guilty of any crime. To give his protestation the greater weight, he uses an imprecation. If he has done any wrong, he declares his readiness to bear the blame; yea, he offers to endure the severest punishment, if he is not altogether innocent of the crime of which all men thought him almost convicted. And by entreating God to succour him upon no other condition than this, that his integrity should upon trial be found to be untarnished, he teaches us, by his example, that as often as we have recourse to God, we must make it our first care to be well assured in our own consciences with respect to the righteousness of our cause; for we do him great wrong if we wish to engage him as the advocate and defender of a bad cause. The pronoun this shows that he speaks of a thing which was generally known; whence we may conclude, that the slander which had been raised by Cush was spread far and wide. And as David was condemned, by the false reports and unrighteous judgments which men advanced against him, and saw no remedy on earth, he betakes himself to the judgment-seat of God, and contents himself with maintaining his innocence before the heavenly Judge; an example which all the godly should imitate, in order that, in opposition to the slanderous reports which are spread against them, they may rest satisfied with the judgment of God alone. He next declares more distinctly, that he had committed no crime. And in the fourth verse, he mentions two particulars in self-vindication; first, That he had done no wrong to any one; and, secondly, That he had rather endeavoured to do good to his enemies, by whom notwithstanding he had been injured without any just cause. I, therefore, explain the fourth verse thus: If I have wronged any man that was at peace with me, and have not rather succoured the unworthy, who persecuted me without a cause, etc. Since David was hated of almost all men, as if ambition to reign had impelled him perfidiously to rise up in rebellion against Saul, and to lay snares for the monarch to whom he was bound by the oath of allegiances [1] in the first part of the verse, he clears himself of such a foul slander. The reason, perhaps, why he calls Saul him that was at peace with him is, that on account of his royal dignity his person ought to be sacred, and secure from danger, [2] so that it should be unlawful to make any hostile attempt against him. This phrase, however, may be understood generally, as if he had said, No one who has meekly restrained himself from injuring me, and has conducted himself kindly towards me, can with truth complain that I have ever injured him in a single instance. And yet it was the general persuasion, that David, in the midst of peace, had stirred up great confusion, and caused war. From this it is just so much the more manifest, that David, provided he enjoyed the approbation of God, was contented with the consolation arising from this, though he should have comfort from no other source. In the second clause of the fourth verse, he proceeds farther, and states, that he had been a friend, not only to the good, but also to the bad, and had not only restrained himself from all revenge, but had even succoured his enemies, by whom he had been deeply and cruelly injured. It would certainly not be very illustrious virtue to love the good and peaceable, unless there were joined to this self-government and gentleness in patiently bearing with the bad. But when a man not only keeps himself from revenging the injuries which he has received, but endeavours to overcome evil by doing good, he manifests one of the graces of a renewed and sanctified nature, and in this way proves himself to be one of the children of God; for such meekness proceeds only from the Spirit of adoption. With respect to the words: as the Hebrew word chlts chalats, which I have translated to delivers signifies to divide and to separate, some, to prevent the necessity of supplying any word to make out the sense, [3] thus explain the passage, If I have withdrawn myself from my persecutors, in order not to succour them. The other interpretation, however, according to which the verb is rendered to deliver or rescue from danger, is more generally received; because the phrase, to separate or set aside, is applied to those things which we wish to place in safety. And thus the negative word not must be supplied, an omission which we will find not unfrequently occurring in The Psalms.

O Lord my God - A solemn appeal to God as to the sincerity and truth of what he was about to say.
If I have done this - This thing charged upon me, for it is evident that "Cush," whoever he was, had accused him of some wrong thing - some wicked action. What that was can only be learned from what follows, and even this is not very specific. So far as appears, however, it would seem to be that he accused David of bringing evil, in some way, upon one who was at peace with him; that is, of wantonly and without provocation doing him wrong, and of so doing wrong that he had the avails of it in his own possession - some spoil, or plunder, or property, that he had taken from him. The charge would seem to be, that he had made a wanton and unprovoked attack on one who had not injured him, and that he had taken, and had still in his possession, something of value that properly belonged to another. Whether the accuser (Cush) in this referred to himself or to some other person, does not appear clear from the psalm; but as he was filled with rage, and as the life of David was endangered by him, it would seem most probable that the reference was to himself, and that he felt he had been personally wronged. The design of David, in the passage now before us, is to deny this charge altogether. This he does in the most explicit manner, by saying that this was so far from being true, that he had, on the contrary, delivered the life of him that was his enemy, and by adding that, if this were so, he would be willing that the injured man should persecute and oppose him, and even trample his life down to the earth.
If there be iniquity in my hands - That is, if there is the iniquity referred to; or, in other words, if he had in his possession what had been wrongfully taken from another, to wit, as appears, from this "Cush" who now accused him. The word "iniquity" here denotes an "unjust possession" - a property that had been unjustly taken from another; and, as remarked above, the slanderous charge would seem to have been, that he had taken that property from some one who was at peace with him, and that he retained it contrary to justice. This charge David means peremptorily to deny.

If I have done this - David was accused by Saul of affecting the kingdom; and of waiting for an opportunity to take away the life of his king, his patron, and his friend. In his application to God he refers to these charges; meets them with indignation; and clears himself of them by a strong appeal to his Judge; and an imprecation that, if he had meditated or designed any such thing, he might meet with nothing but curse and calamity either from God or man.

O LORD my God, if I have done (b) this; if there be iniquity in my hands;
(b) With which Cush charges me.

O Lord my God, if I have done this. The crime which Saul and his courtiers charged him with, and which was made so public that every body knew it; and therefore it was needless particularly to mention it; namely, that he lay in wait for Saul, and sought his life to take it away, 1-Samuel 24:9. The Targum interprets it of this psalm, paraphrasing it, "if I have made this song with an evil intention"; to give an ill character of any, and lead them with false charges;
if there be iniquity in my hands; not that he was without sin, he had it in his heart; nor that he lived without the actual commission of sin: but his sense is, that there was no iniquity, as not in his heart, purpose, and design, so not in his hand, nor attempted by him, of the kind he was accused of, 1-Samuel 24:11. Otherwise, we often hear him complaining of the depravity of his nature, and acknowledging his sins and transgressions, Psalm 32:5.

if I have done this--that is, the crime charged in the "words of Cush" (compare 1-Samuel 24:9).

(Hebrews.: 7:4-6) According to the inscription זאת points to the substance of those slanderous sayings of the Benjamite. With בּכפּי אם־ישׁ־עול one may compare David's words to Saul אין בּידי רעה 1-Samuel 24:12; 1-Samuel 26:18; and from this comparison one will at once see in a small compass the difference between poetical and prose expression. שׁלמי (Targ. לבעל שׁלמי) is the name he gives (with reference to Saul) to him who stands on a peaceful, friendly footing with him, cf. the adject. שׁלום, Psalm 55:21, and אישׁ שׁלום, Psalm 41:10. The verb גּמל, cogn. גּמר, signifies originally to finish, complete, (root גם, כם ,גם t, cf. כּימה to be or to make full, to gather into a heap). One says טּוב גּמל and גּמל רע, and also without a material object גּמל עלי or גּמלני benefecit or malefecit mihi. But we join גּמלתּי with רע according to the Targum and contrary to the accentuation, and not with שׁלמי (Olsh., Bttch., Hitz.), although שׁלם beside משׁלּם, as e.g., דּבר beside מדבּר might mean "requiting." The poet would then have written: אם שׁלּמתּי גּמלי רע i.e., if I have retaliated upon him that hath done evil to me. In Psalm 7:5 we do not render it according the meaning to הלּץ which is usual elsewhere: but rather I rescued... (Louis de Dieu, Ewald 345, a, and Hupfeld). Why cannot הלּץ in accordance with its primary signification expedire, exuere (according to which even the signification of rescuing, taken exactly, does not proceed from the idea of drawing out, but of making loose, exuere vinclis) signify here exuere = spoliare, as it does in Aramaic? And how extremely appropriate it is as an allusion to the incident in the cave, when David did not rescue Saul, but, without indeed designing to take חליצה, exuviae, cut off the hem of his garment! As Hengstenberg observes, "He affirms his innocence in the most general terms, thereby showing that his conduct towards Saul was not anything exceptional, but sprang from his whole disposition and mode of action." On the 1 pers. fut. conv. and ah, vid., on Psalm 3:6. ריקם belongs to צוררי, like Psalm 25:3; Psalm 69:5.
In the apodosis, Psalm 7:6, the fut. Kal of רדף is made into three syllables, in a way altogether without example, since, by first making the Sheb audible, from ירדּף it is become ירדף (like יצחק Genesis 21:6, תּהלך Psalm 73:9; Exodus 9:23, שׁמעה Psalm 39:13), and this is then sharpened by an euphonic Dag. forte.
(Note: The Dag. is of the same kind as the Dag. in גּמלּים among nouns; Arabic popular dialect farassı̂ (my horse), vid., Wetzstein's Inshriften S. 366.)
Other ways of explaining it, as that by Cahjg = יתרדף, or by Kimchi as a mixed form from Kal and Piel,
(Note: Pinsker's view, that the pointing ירדף is designed to leave the reader at liberty to choose between the reading ירדּף and ירדּף, cannot be supported. There are no safe examples for the supposition that the variations of tradition found expression in this way.)
have been already refuted by Baer, Thorath Emeth, p. 33. This dactylic jussive form of Kal is followed by the regular jussives of Hiph. ישּׂג and ישׁכּן. The rhythm is similar so that in the primary passage Exodus 15:9, which also finds its echo in Psalm 18:38, - viz. iambic with anapaests inspersed. By its parallelism with נפשׁי and חיּי, כּבודי acquires the signification "my soul," as Saadia, Gecatilia and Aben-Ezra have rendered it - a signification which is secured to it by Psalm 16:9; 30:13; Psalm 57:9; Psalm 108:2, Genesis 49:6. Man's soul is his doxa, and this it is as being the copy of the divine doxa (Bibl. Psychol. S. 98, [tr. p. 119], and frequently). Moreover, "let him lay in the dust" is at least quite as favourable to this sense of כבודי as to the sense of personal and official dignity (Psalm 3:4; Psalm 4:3). To lay down in the dust is equivalent to: to lay in the dust of death, Psalm 22:16. שׁכני עפר, Isaiah 26:19, are the dead. According to the biblical conception the soul is capable of being killed (Numbers 35:11), and mortal (Numbers 23:10). It binds spirit and body together and this bond is cut asunder by death. David will submit willingly to death in case he has ever acted dishonourably.
Here the music is to strike up, in order to give intensity to the expression of this courageous confession. In the next strophe is affirmation of innocence rises to a challenging appeal to the judgment-seat of God and a prophetic certainty that that judgment is near at hand.

Hands - Which Cush and others falsely lay to my charge. Iniquity - In my actions.
