Deuteronomy 11:16-17

Take heed to yourselves, lest your heart be deceived, and ye turn aside, and serve other gods, and worship them; and the anger of Jehovah be kindled against you, and he shut up the heavens, so that there shall be no rain, and the land shall not yield its fruit; and ye perish quickly from off the good land which Jehovah giveth you.
