Leviticus 26:35-36

³⁵As long as it lies desolate it shall have rest, even the rest which it didn’t have in your Sabbaths when you lived on it.

³⁶“‘As for those of you who are left, I will send a faintness into their hearts in the lands of their enemies. The sound of a driven leaf will put them to flight; and they shall flee, as one flees from the sword. They will fall when no one pursues.
