1 Samuel 23:7-8
7-8Saul learned that David had gone to Keilah and thought immediately, "Good! God has handed him to me on a platter! He's in a walled city with locked gates, trapped!" Saul mustered his troops for battle and set out for Keilah to lay siege to David and his men.
9-11But David got wind of Saul's strategy to destroy him and said to Abiathar the priest, "Get the Ephod." Then David prayed to God: "God of Israel, I've just heard that Saul plans to come to Keilah and destroy the city because of me. Will the city fathers of Keilah turn me over to him? Will Saul come down and do what I've heard? O God, God of Israel, tell me!"
God replied, "He's coming down."
