Leviticus 26:36-37

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. {shaken: Heb. driven} 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.
