To the chief Musician, Maschil, A Psalm of David, when Doeg the Edomite came and told Saul, and said unto him, David is come to the house of Ahimelech. Why boastest thou thyself in mischief, O mighty man? the goodness of God endureth continually. Why boastest thou thyself - It is thought that Doeg boasted of his loyalty to Saul in making the above discovery; but the information was aggravated by circumstances of falsehood that tended greatly to inflame and irritate the mind of Saul. Exaggeration and lying are common to all informers.
O mighty man? - This character scarcely comports with Doeg, who was only chief of the herdsmen of Saul, 1 Samuel 21:7; but I grant this is not decisive evidence that the Psalm may not have Doeg in view, for the chief herdsman may have been a man of credit and authority.
