Psalms 109:16

16.Because he forgot to show mercy The prophet comes now to show that he had good reason for desiring such awful and direful calamities to be inflicted upon his enemies, whose thirst for cruelty was insatiable, and who were transported with rage, no less cruel than obstinate, against the afflicted and poor man, persecuting him with as little scruple as if they were attacking a dead dog. Even philosophers look upon cruelty, directed against the helpless and miserable, as an act worthy only of a cowardly and grovelling nature; for it is between equals that envy is cherished. For this reason the prophet represents the malignity of his enemies as being bitter in persecuting him when he was in affliction and poverty. The expression, the sorrowful in heart, is still more emphatic. For there are persons who, notwithstanding of their afflictions, are puffed up with pride; and as this conduct is unreasonable and unnatural, these individuals incur the displeasure of the powerful. On the other hand, it would be a sign of desperate cruelty to treat with contempt the lowly and dejected in heart. Would not this be to fight with a shadow? This insatiable cruelty is still farther pointed out by the phrase, forgetting to show mercy; the meaning of which is, that the calamities, with which he beheld this guiltless and miserable man struggling, fail to excite his pity, so that, out of regard to the common lot of humanity, he should lay aside his savage disposition. In this passage, therefore, the contrast is equally balanced on the one side between such obstinate pride, and on the other, the strict and irrevocable judgment of God. And as David spoke only as he was moved by the Holy Spirit, this imprecation must be received as if God himself should thunder from his celestial throne. Thus, in the one case, by denouncing vengeance against the ungodly, he subdues and restrains our perverse inclinations, which might lead us to injure a fellow-creature; and on the other, by imparting comfort to us, he mitigates and moderates our sorrow, so that we patiently endure the ills which they inflict upon us. The wicked may for a time revel with impunity in the gratification of their lusts; but this threatening shows that it is no vain protection which God vouchsafes to the afflicted. But let the faithful conduct themselves meekly, that their humility and contrition of spirit may come up before God with acceptance. And as we cannot distinguish between the elect and the reprobate, it is our duty to pray for all who trouble us; to desire the salvation of all men; and even to be careful for the welfare of every individual. At the same time, if our hearts are pure and peaceful, this will not prevent us from freely appealing to God’s judgment, that he may cut off the finally impenitent. (310)
