10 David asked God for advice: "Should I attack the Philistines, and will you hand them over to me?"The Lord answered, "Attack them, and I’ll definitely hand them over to you."
11 So they marched up to Baal-perazim, and David defeated them there. "By my strength," David exclaimed, "God has burst out against my enemies, the way water bursts out." That’s why the place is called Baal-perazim.
12 The Philistines left their divine images behind, and David ordered them burned.
13 When the Philistines plundered the valley a second time,
14 David again asked God’s advice, but God answered, "Don’t attack them directly. Circle around behind them and come at them from in front of the balsam trees.
15 As soon as you hear the sound of marching in the tops of the trees, then attack, for God has attacked in front of you to defeat the Philistine army."
16 David followed God’s orders exactly, and they defeated the Philistine army from Gibeon all the way to Gezer.
