13 Some time later, the Philistines came back into the hill country and camped in Rephaim Valley.
14 David asked God what he should do, and God answered, “Don't attack them from the front. Circle around behind them where the balsam trees are.
15 Wait there until you hear the treetops making the sound of marching troops. That sound will mean I have marched out ahead of you to fight the Philistine army. So you must then attack quickly!”
16 David obeyed God and he defeated the Philistines. He even chased them all the way from Gibeon to the entrance to Gezer.
17 From then on, David became even more famous, and the Lord made all the nations afraid of him.
