1 Samuel 23:5-12

5So David and his men went to Keilah, and fought with 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, that he came down with an ephod in his hand.

7And it was told to Saul that David had 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 called all the people together to war, to go down to Keilah, to besiege David and his men. 9And David knew that Saul secretly devised mischief against him; and he said to Abiathar the priest, Bring here the ephod. 10Then said David, O LORD God of Israel, thy servant hath certainly heard that Saul seeketh to come to Keilah, to destroy the city for my sake. 11Will the men of Keilah deliver me up into his hand? will Saul come down, as thy servant hath heard? O LORD God of Israel, I beseech thee, tell thy servant. And the LORD said, He will come down. 12Then said David, Will the men of Keilah deliver me and my men into the hand of Saul? And the LORD said, They will deliver thee up.1
