David
Psalm 52:1ESV·traditional attribution

Why do you boast of evil, O mighty man? The steadfast love of God endures all the day.

John Calvin Reformed @genevareformer

PSALM 52 This psalm was composed by David at the time when the death of Abimelech and the other priests had spread universal tenor among the people, indisposing them for lending any countenance to his cause, and when Doeg was triumphing in the successful issue of his information.

C.H. Spurgeon Reformed Baptist @princeofpreachers

Why boasteth thyself in mischief, O mighty man? Doeg had small matter for boasting in having procured the slaughter of a band of defenceless priests. A mighty man indeed to kill men who never touched a sword! He ought to have been ashamed of his cowardice. He had no room for exultation! Honourable titles are but irony where the wearer is mean and cruel.

Matthew Henry Presbyterian @wholebiblehenry

The title is a brief account of the story which the psalm refers to. David now, at length, saw it necessary to quit the court, and shift for his own safety, for fear of Saul, who had once and again attempted to murder him. Being unprovided wit harms and victuals, he, by a wile, got Ahimelech the priest to furnish him with both.
