Leviticus 26:17, 36-37

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

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