1 Samuel 23:4-7

So David asked the LORD again, and again the LORD replied, “Go down to Keilah, for I will help you conquer the Philistines.” So David and his men went to Keilah. They slaughtered the Philistines and took all their livestock and rescued the people of Keilah. Now when Abiathar son of Ahimelech fled to David at Keilah, he brought the ephod with him. Saul soon learned that David was at Keilah. “Good!” he exclaimed. “We’ve got him now! God has handed him over to me, for he has trapped himself in a walled town!”
