17 As he loved cursing David still continues to enumerate the sins of his adversaries, and is thus severe in his treatment of them, in order to render it more apparent, that he is strictly conforming to the judgment of God. For as often as we draw near to the tribunal of God, we must take care that the equity of our cause may be so sure and evident as to secure for it and us a favorable reception from him. Fortified by the testimony of an approving conscience, David here declares his readiness to commit the matter between him and his enemies to the judgment of God. The words, which are expressive of cursing and blessing, are in the past tense, cursing came upon him, and blessing was far from him, but it is necessary to translate them as expressive of a wish or desire; for David continues to pray that his enemy may be visited with the same unparalleled ills which he had inflicted upon others. A stranger to every act of kindness, and taking pleasure in doing evil, it is the wish of the Psalmist that he may now be subjected to every species of calamity. Some take malediction to mean cursing and imprecation, thereby intimating that this man was so addicted to execration, that mischief and malevolence were constantly in his heart, and proceeding from his lips. While I do not reject this opinion, I am yet disposed to take a more extended view of the passage, That by injury and abuse, he aimed at the suppression and abolition of every mark of kindness, and that he took delight in the calamities which he beheld coming upon the unsuspecting and the good.

Not a few interpreters translate the next two verses in the past form, he clothed himself with cursing, etc., which would be tantamount to saying that the enemy was as fond of cursing as of costly apparel, or that he clothed himself with it as with a garment, and that, like an inveterate disease, it was deeply seated in the marrow of his bones. The other interpretation is more simple, That cursing should cleave to the wicked, that it should envelop him like a cloak, gird him about as his girdle, and should even penetrate to his bones. And that no one may rashly take for an example what David here spoke by the special influence of the Holy Spirit, let him keep in mind that the Psalmist is not pleading here in reference to any personal interest, and that it is no ordinary character to whom he refers. Belonging to the number of the faithful, he would not omit the law of charity, in desiring the salvation of all men. But in this instance God elevated his spirit above all earthly considerations, stript him of all malice, and delivered him from the influence of turbulent passion, so that he might, with holy calmness and spiritual wisdom, doom the reprobate and castaway to destruction. Others, would have the phrase, he loved cursing, to mean that he purposely drew down the vengeance of God upon himself, as it were procuring destruction for himself by his open hostility to him; but this is an unnatural construction of the passage. The interpretation which I have given is preferable, That he was so addicted to mischief and wrong, that no act of justice or kindness was to be expected from him. In the meantime, let it be observed, that all the machinations of the wicked will eventually recoil upon their own heads, and that when they are raging more violently against others, then it is that the mischief, which they so eagerly desire may come upon them, falls upon themselves, even as the wind called Cecias by blowing attracts the clouds unto him.

20 Let this be the work from Jehovah. That is, let the gain or reward of the work be from God. In pointing out the work as proceeding immediately from God, he intends to show that, though deprived of all human aid, he yet entertained the hope that God would grant him deliverance, and avenge the injuries of his servant. From this verse we learn that David did not rashly, or unadvisedly, utter curses against his enemies, but strictly adhered to what the Spirit dictated. I acknowledge, indeed, that not a few, while they pretend a similar confidence and hope, nevertheless, recklessly rush beyond the bounds of temperance and moderation. But that which David beheld by the unclouded eye of faith, he also uttered with a zeal becoming a sound mind; for having devoted himself to the cultivation of piety, and being protected by the hand of God, he was aware that the day was approaching when his enemies would meet with merited punishment. From which we also learn, that his trust was placed in God alone, and that he did not regard the persons of men so as to direct his course according as the world smiled or frowned upon him. And, assuredly, whosoever places his dependence on men, shall find that the most trifling incident will annoy him. Therefore, should the whole world abandon us, it becomes us, in imitation of this holy man, to lift up our heads to heaven, and thence look for our defender and deliverer. If it be his intention to employ human instrumentality for our deliverance, he will soon raise up those who will accomplish his purpose. Should he, for the trial of our faith, deprive us of all earthly assistance, instead of regarding that as any reflection upon the glory of his name, we ought to wait until the proper time arrive when he will fully display that decision in which we can calmly acquiesce.
