Mishnà su Levitico 26:19

Seven kinds of punishment come to the world for seven categories of transgression:When some of them give tithes, and others do not give tithes, a famine from drought comes some go hungry, and others are satisfied. When they have all decided not to give tithes, a famine from tumult and drought comes; [When they have, in addition, decided] not to set apart the dough-offering, an all-consuming famine comes. Pestilence comes to the world for sins punishable by death according to the Torah, but which have not been referred to the court, and for neglect of the law regarding the fruits of the sabbatical year. The sword comes to the world for the delay of judgment, and for the perversion of judgment, and because of those who teach the Torah not in accordance with the accepted law.
