1 Samuel 23:1-10

And they told David, saying, Behold, the Philistines are fighting against Keilah, and are robbing the threshing-floors. Therefore 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. And 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? Then 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. And 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. And 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. And 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. And Saul summoned all the people to war, to go down to Keilah, to besiege David and his men. And David knew that Saul was devising mischief against him; and he said to Abiathar the priest, Bring hither the ephod. Then said David, O Jehovah, the God of Israel, thy servant hath surely heard that Saul seeketh to come to Keilah, to destroy the city for my sake.
