Psalms 52:6,7 - Joseph Benson’s Commentary on the Old and New Testaments

The righteous also shall see Namely, thy remarkable downfall, and, consequently, shall survive thee, in spite of all thy malice and violence against them; and fear Shall reverence God's just judgment upon thee, and be afraid of provoking him. And shall laugh at him Not taking pleasure in his ruin, considered in itself, but only in the glory of God's justice vindicated thereby, (Revelation 18:20,) and deriding his vain and carnal confidence in his wicked courses. “The peculiar judgments of God, executed upon exemplary offenders, who have been guilty of treachery, rapine, and murder, good men will carefully observe; and observe, though with awe, yet thankfulness; not that they rejoice to see the punishments and miseries of mankind, separately considered; no person of humanity taking pleasure in the execution of criminals as such; but as the administration of justice is always a right, and, so far, a pleasant thing; as instances of God's vengeance are sometimes necessary to keep men in tolerable order; and as the cutting off such kind of incorrigible offenders prevents them from doing further mischiefs, and is so far a public and common blessing to mankind. It was therefore impossible that any good man, who had seen the crimes of this treacherous and bloody Edomite retaliated on him by Divine Providence, should do otherwise than approve so righteous a retribution, and when he observed it, forbear to say, as in Psalms 52:7, Lo, this is the man, &c.” The great and famous man, that made not God his strength That trusted in and feared Saul more than God, and was willing to purchase Saul's favour with God's displeasure; but trusted in the abundance of his riches Thought himself secure in his great and growing wealth without God's protection or blessing. “Observe the fate of this haughty slanderer and murderer! Where now are all his boasted riches and prosperity?” He and they are separated for ever! See Dodd and Chandler.
