1 Chronicles 14:15-17

14:15 When you hear the sound of marching in the tops of the trees, then attack. For at that moment the Lord is going before you to strike down the army of the Philistines.” 14:16 David did just as God commanded him, and they struck down the Philistine army from Gibeon to Gezer.

14:17 So David became famous in all the lands; the Lord caused all the nations to fear him.
