2 Samuel 5:23-24

23When 1David inquired of the Lord, He said, “You shall not go directly up; circle around behind them and come at them in front of the 2balsam trees.

24It shall be, when 3you hear the sound of marching in the tops of the 4balsam trees, then you shall act promptly, for then 5the Lord will have gone out before you to strike the army of the Philistines.”
