1 Samuel 23:4-12

4Once again David inquired of the Lord, and the Lord answered him, “Go down to Keilah, for I am going to give the Philistines into your hand.” 5So David and his men went to Keilah, fought the Philistines and carried off their livestock. He inflicted heavy losses on the Philistines and saved the people of Keilah. 6(Now Abiathar son of Ahimelek had brought the ephod down with him when he fled to David at Keilah.) 7Saul was told that David had gone to Keilah, and he said, “God has delivered him into my hands, for David has imprisoned himself by entering a town with gates and bars.” 8And Saul called up all his forces for battle, to go down to Keilah to besiege David and his men. 9When David learned that Saul was plotting against him, he said to Abiathar the priest, “Bring the ephod.” 10David said, “Lord, God of Israel, your servant has heard definitely that Saul plans to come to Keilah and destroy the town on account of me. 11Will the citizens of Keilah surrender me to him? Will Saul come down, as your servant has heard? Lord, God of Israel, tell your servant.” And the Lord said, “He will.” 12Again David asked, “Will the citizens of Keilah surrender me and my men to Saul?” And the Lord said, “They will.”
