Then David asked of God, saying, Shall I go up against the Philistines? and wilt thou deliver them into my hand? And Yahweh said to him, Go up, and I will deliver them into thy hand.

and it shall be, when thou hearest a sound of marching in the tops of the mulberry-trees, then, shalt thou go forth into the battle, - for God will have gone forth before thee, to smite the host of the Philistines.
