Psalms 52:1 - Ellicott's Commentary On The Whole Bible

Mighty man. — Better, hero, used sarcastically. LXX. and Vulg., “a mighty one at mischief.” (Comp. Isaiah 5:22 : “a hero at drinking.”) The order of the Hebrew is, however, against this, and in favour of the English, why dost thou exult in wickedness, O hero, i.e., perhaps, not only his own, but in the wickedness the people are led into by his means. This seems necessitated by the next clause. In spite of man’s folly and sin, God’s covenant favour endures all the day long.
