1 Samuel 23:8

⁶  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.

⁷  And 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.

⁸  And Saul called all the people together to war, to go down to Keilah, to besiege David and his men.

⁹  And David knew that Saul secretly practiced mischief against him; and he said to Abiathar the priest, Bring hither the ephod.

¹⁰  Then 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.
