1 Chronicles 14:14-16

Amplified Bible

¹⁴ So David inquired again of God, and God said to him, “Do not go up after them; circle around behind them and come at them in front of the balsam trees. ¹⁵ It shall be when you hear the sound of marching in the tops of the balsam trees, then you shall go out to battle, for God has gone out before you to strike the Philistine army.” ¹⁶ So David did just as God had commanded him, and they struck down the army of the Philistines from Gibeon as far as Gezer.
