Leviticus 26:35-36

35All the days of its desolation it will observe the rest which it did not observe on your sabbaths, while you were living on it.

36As for those of you who may be left, I will also bring 1weakness into their hearts in the lands of their enemies. And the sound of a driven leaf will chase them, and even when no one is pursuing they will flee 2as though from the sword, and they will fall.
