21 The Philistines abandoned their idols there, and David and his men carried them off.
22 The Philistines came up again and spread out in the Valley of Rephaim.
23 So David inquired of the Lord, and He answered, “Do not make a frontal assault. Circle around behind them and attack them opposite the balsam trees.
24 When you hear the sound of marching in the tops of the balsam trees, act decisively, for then the Lord will have marched out ahead of you to attack the camp of the Philistines.”
25 So David did exactly as the Lord commanded him, and he struck down the Philistines all the way from Geba to Gezer.
