1 Samuel 23:4-5

4 Once 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.”
5 So 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.
