Divine retribution for evil was the truth of the Old Testament, as forgiveness is that of the New. The conflict between God's kingdom and its enemies was being keenly and perpetually waged, in most literal fashion. Devout men could not but long for the triumph of that with which all good was associated, and therefore for the defeat and destruction of its opposite. For no private injuries, or for these only in so far as the suffering singer is a member of the community which represents God's cause, does he ask the descent of God's vengeance, but for the insults and hurts inflicted on righteousness. The form of these maledictions belongs to a lower stage of revelation; the substance of them, considered as passionate desires for the destruction of evil, burning zeal for the triumph of Truth, which is God's cause, and unquenchable faith that He is just, is a part of Christian perfection.
The usual variety of conjectures as to authorship exists. Delitzsch hesitatingly accepts the superscription as correct in assigning the psalm to David. Olshausen, as is his custom, says, "Maccabean"; Cheyne inclines to "the time of Nehemiah (in which case the enemy might be Sanballat), or even perhaps the close of the Persian age" ("Orig. of Psalt.," 65). He thinks that the "magnanimous David" could not have uttered "these laboured imprecations," and that the speaker is "not a brave and bold warrior, but a sensitive poet." Might he not be both?
To address God as the "God of my praise," even at such a moment of dejection, is a triumph of faith. The name recalls to the psalmist past mercies, and expresses his confidence that he will still have cause to extol his Deliverer, while it also pleads with God what He has done as a reason for doing the like in new circumstances of need. The suppliant speaks in praise and prayer; he asks God to speak in acts of rescuing power. A praying man cannot have a dumb God. And His mighty Voice, which hushes all others and sets His suppliants free from fears and foes, is all the more longed for and required, because of those cruel voices that yelp and snarl round the psalmist. The contrast between the three utterances--his, God's, and his enemies'--is most vivid. The foes have come at him with open mouths. "A wicked man's mouth" would read, by a slight alteration, "a mouth of wickedness"; but the recurrence of the word "wicked man" in ver. 6 seems to look back to this verse, and to make the rendering above probable. Lies and hatred ring the psalmist round, but his conscience is clear. "They have hated me without a cause" is the experience of this ancient sufferer for righteousness' sake, as of the Prince of all such. This singer, who is charged with pouring out a flood of "unpurified passion," had, at any rate, striven to win over hatred by meekness; and if he is bitter, it is the pain and bitterness of love flung back with contumely, and only serving to exacerbate enmity. Nor had he met with evil the first returns of evil for good, but, as he says, "I was [all] prayer" (compare Psalm cxx. 7, "I am--peace"). Repelled, his whole being turned to God, and in calm communion with Him found defence and repose. But his patient meekness availed nothing, for his foes still "laid evil" on him in return for good. The prayer is a short record of a long martyrdom. Many a foiled attempt of patient love preceded the psalm. Not till the other way had been tried long enough to show that malignity was beyond the reach of conciliation did the psalmist appeal to the God of recompenses. Let that be remembered in judging the next part of the psalm.
The terrible maledictions (vv. 6-20) need little commentary. They may be left in all their awfulness, which is neither to be extenuated nor degraded into an outburst of fierce personal vindictiveness. It is something far more noble than that. These terrible verses are prophecy, but they are prayers too; and prayers which can only be accounted for by remembering the spirit of the old dispensation. They are the more intense, because they are launched against an individual, probably the chief among the foes. In vv. 6-15 we have imprecations pure and simple, and it is noteworthy that so large a part of these verses refers to the family of the evil-doer. In vv. 16-20 the grounds of the wished-for destruction are laid in the sinner's perverted choice, and the automatic action of sin working its own punishment is vividly set forth.
