2 Samuel 5:23-24

23  a And when David inquired of the  Lord, he said, “You shall not go up; go around to their rear, and come against them opposite the balsam trees. 24 And b when you hear the sound of marching in the tops of the balsam trees, then rouse yourself, c for then the  Lord has gone out before you to strike down the army of the Philistines.”
