Psalms 52:1 - Joseph Benson’s Commentary on the Old and New Testaments

Why boastest thou thyself &c. As if thou hadst done a great exploit, which none else durst undertake; and thereby established the crown upon Saul's head, and thyself in his favour; and frustrated all David's designs, by striking a terror into all his friends, by this sad example; O mighty man? He speaks ironically. O valiant captain! O glorious action! To kill a few weak and unarmed persons in the king's presence, and under the protection of his guards. Surely thy name will be famous to all ages for such heroical courage! It seems probable that Doeg, after he had massacred the priests, boasted of his loyalty to Saul, and of having prevented the treasonable schemes which, he artfully insinuated, had been concerted by David and the priests; and that he had been liberally rewarded by Saul on account of it; and that this is the reason why the Psalm begins in thus expressing a kind of contempt of Doeg. See Dodd. The goodness of God endureth continually Know, vain man, that I am out of the reach of thy malice. That goodness of God, which thou reproachest me for trusting in, is my sure protection, and will follow me day by day; and, surely, that same goodness, together with his forbearance and long-suffering, is wonderfully displayed in sparing thee, amidst thy complicated crimes, who art continually doing evil; while he is continually doing good.
