2 Samuel 5:22–25

22 The Philistines came up again and spread out in Rephaim Valley. 23 So David inquired of the Lord, and he answered, “Do not attack directly, but circle around behind them and come at 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 gone out ahead of you to strike down the army of the Philistines.”q 25 So David did exactly as the Lord commanded him, and he struck down the Philistines all the way from Geba to Gezer.
