Leviticus 26:17, 36-37

And I will set my face against you, and ye shall be smitten before your enemies: they that hate you shall rule over you; and ye shall flee when none pursueth you.

And as for them that are left of you, I will send a faintness into their heart in the lands of their enemies: and the sound of a driven leaf shall chase them; and they shall flee, as one fleeth from the sword; and they shall fall when none pursueth. And they shall stumble one upon another, as it were before the sword, when none pursueth: and ye shall have no power to stand before your enemies.
