1 Samuel 23:2–9

²And David inquired of Jehovah, saying, Shall I go and smite these Philistines? And Jehovah said to David, Go and smite the Philistines, and save Keilah. ³But David’s men said to him, Behold, we are afraid here in Judah; how much more then if we go to Keilah against the armies of the Philistines? ⁴And David inquired of Jehovah yet again. And Jehovah answered him and said, Arise, go down to Keilah; for I will give the Philistines into thy hand. ⁵And David and his men went to Keilah, and fought against the Philistines, and brought away their cattle, and smote them with a great slaughter. So David saved the inhabitants of Keilah. ⁶And it came to pass, when Abiathar the son of Ahimelech fled to David to Keilah, he came down with an ephod in his hand.

⁷And it was told Saul that David had come to Keilah. Then Saul said, God has cast him off into my hand; for he is shut in, by entering into a city that has gates and bars. ⁸And Saul summoned all the people to war, to go down to Keilah, to besiege David and his men. ⁹And when David knew that Saul devised mischief against him, he said to Abiathar the priest, Bring the ephod.
