Deuteronomy 28:59-62

59then Adonai will make your plagues and the plagues of your descendants extraordinary—terrible and prolonged plagues, severe and prolonged illnesses.

60He will bring back on you all the diseases of Egypt that you were afraid of, and they will cling to you.

61Also every illness and plague that is not written in the scroll of this Torah, Adonai will bring on you, until you are destroyed.

62“You will be left few in number, instead of being like the stars of the sky in number—because you did not listen to the voice of Adonai your God.
