Leviticus 26:32, 36

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

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.
