Deuteronomy 28:58-63

If thou wilt not observe to do all the words of this law that are written in this book, that thou mayest fear this glorious and fearful name, JEHOVAH THY GOD; then Jehovah will make thy plagues wonderful, and the plagues of thy seed, even great plagues, and of long continuance, and sore sicknesses, and of long continuance. And he will bring upon thee again all the diseases of Egypt, which thou wast afraid of; and they shall cleave unto thee. Also every sickness, and every plague, which is not written in the book of this law, them will Jehovah bring upon thee, until thou be destroyed. And ye shall be left few in number, whereas ye were as the stars of heaven for multitude; because thou didst not hearken unto the voice of Jehovah thy God. And it shall come to pass, that, as Jehovah rejoiced over you to do you good, and to multiply you, so Jehovah will rejoice over you to cause you to perish, and to destroy you; and ye shall be plucked from off the land whither thou goest in to possess it.
