1 Chronicles 14:14-15

14And David inquired again of 1God; and 2God said to him, Go not up after them; turn round them and come upon them opposite the mulberry-trees.

15And it shall be, when thou hearest the sound of marching in the tops of the mulberry-trees, that then thou shalt go out to battle; for 3God will have gone forth before thee to smite the army of the Philistines.
