Psalms 52:1
1Why do you boast of mischief, mighty man? God’s loving kindness endures continually.
Why boast of mischief, mighty man?—while God’s steadfast love endures all the day. Wesley: Continually—God is continually doing good; thou art continually doing mischief. O mighty—ironic: O valiant captain! to kill a few weak and unarmed persons.
The boast is exposed as empty beside God’s ongoing goodness. Grace that endures all day still summons the hearer to stop glorying in mischief; Doeg’s choice to boast is guilt, not fate.
Calvin: Doeg’s success staggered faith; David arms himself with holy defiance. The aggravation is boasting in power won by consummate villainy. Triumph by violence and treachery is short-lived; such men despise providence over God’s children.
David’s confidence challenges proud boasters who dishonor God’s goodness. God’s hesed outlasts the mighty man’s day.
Key contrast Both set Doeg’s boast against God’s enduring goodness. Arminians press the ironic rebuke and the call to quit glorying in mischief under a goodness still offered; Reformed readers stress holy defiance that rests on providence already set against short-lived wicked triumph.
