1 Samuel 23:9 KJV

7And it was told Saul that David was come to Keilah. And Saul said, God hath delivered him into mine 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 practised mischief against him; and he said to Abiathar the priest, Bring hither 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.
