Deuteronomy 28:58-63

“If you do not carefully observe all the words of this law that are written in this book, that you may fear this glorious and awesome name, THE LORD YOUR GOD, then the LORD will bring upon you and your descendants extraordinary plagues—great and prolonged plagues—and serious and prolonged sicknesses. Moreover He will bring back on you all the diseases of Egypt, of which you were afraid, and they shall cling to you. Also every sickness and every plague, which is not written in this Book of the Law, will the LORD bring upon you until you are destroyed. You shall be left few in number, whereas you were as the stars of heaven in multitude, because you would not obey the voice of the LORD your God. And it shall be, that just as the LORD rejoiced over you to do you good and multiply you, so the LORD will rejoice over you to destroy you and bring you to nothing; and you shall be plucked from off the land which you go to possess.
