Leviticus 26:35-36

35As long as it lies desolate it will have rest, that rest which it did not have from your Shabbatot, when you lived on it.

36“As for those who remain, I will bring weakness into their hearts in the lands of their enemies, so that the sound of a driven leaf will put them to flight, and they will flee as one flees from the sword and fall, even when no one is pursuing.
