2 Samuel 5:19-25

19David inquired of the Lord, saying, “Shall I go up against the Philistines? Will You hand them over to me?” And the Lord said to David, “Go up, for I will certainly hand them over to you.”

20So David came to Baal-perazim, and he defeated them there, and said, “The Lord has broken through my enemies before me, like a breakthrough of water.” So he named that place Baal-perazim (master of breakthroughs).

21The Philistines abandoned their [pagan] idols there, so David and his men took them away [to be burned].

22The Philistines came up once again and spread out in the Valley of Rephaim.

23When David inquired of the Lord, He said, “You shall not go up, but circle around behind them and come at them in front of the balsam trees.

24And when you hear the sound of marching in the tops of the balsam trees, then you shall pay attention and act promptly, for at that time the Lord will have gone out before you to strike the army of the Philistines.”

25David did just as the Lord had commanded him, and struck down the Philistines from Geba as far as Gezer.
