Leviticus 26:32, 36

And I will bring the land into desolation: and your enemies which dwell therein shall be astonished at it.

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.
