Question: who is abimelech in psalm 34?
Answer: Psalm 34 attributes its own authorship to David. The Psalm's sub-title, A Psalm of David when he pretended madness before Abimelech, who drove him away, and he departed, derives from when David was living with the Philistines, but the account of this event in 1 Samuel 21 refers to the king as Achish, not Abimelech.
