2 Samuel 5:23-24

And when David inquired of Jehovah, he said, Thou shalt not go up: make a circuit behind them, and come upon them over against the mulberry-trees. And it shall be, when thou hearest the sound of marching in the tops of the mulberry-trees, that then thou shalt bestir thyself; for then is Jehovah gone out before thee to smite the host of the Philistines.
