1 Samuel 23:2–9

²Therefore David inquired of Jehovah, saying, Shall I go and smite these Philistines? And Jehovah said unto David, Go, and smite the Philistines, and save Keilah. ³And David’s men said unto him, Behold, we are afraid here in Judah: how much more then if we go to Keilah against the armies of the Philistines? ⁴Then David inquired of Jehovah yet again. And Jehovah answered him, and said, Arise, go down to Keilah; for I will deliver the Philistines into thy hand. ⁵And David and his men went to Keilah, and fought with the Philistines, and brought away their cattle, and slew 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, that he came down with an ephod in his hand.

⁷And it was told Saul that David was come to Keilah. And Saul said, God hath delivered him into my hand; for he is shut in, by entering into a town that hath gates and bars. ⁸And Saul summoned all the people to war, to go down to Keilah, to besiege David and his men. ⁹And David knew that Saul was devising mischief against him; and he said to Abiathar the priest, Bring hither the ephod.
