1 Chronicles 14:10-11, 14-16

So David asked God, “Should I go out to fight the Philistines? Will you hand them over to me?” The LORD replied, “Yes, go ahead. I will hand them over to you.” So David and his troops went up to Baal-perazim and defeated the Philistines there. “God did it!” David exclaimed. “He used me to burst through my enemies like a raging flood!” So they named that place Baal-perazim (which means “the Lord who bursts through”).

And once again David asked God what to do. “Do not attack them straight on,” God replied. “Instead, circle around behind and attack them near the poplar trees. When you hear a sound like marching feet in the tops of the poplar trees, go out and attack! That will be the signal that God is moving ahead of you to strike down the Philistine army.” So David did what God commanded, and they struck down the Philistine army all the way from Gibeon to Gezer.
