Leviticus 26:36-38

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. And ye shall perish among the heathen, and the land of your enemies shall eat you up.
