Deuteronomy 28:58-63

“If you are not careful to observe all the words of this law which are written in this book, to fear this honored and awesome name, the LORD your God, then the LORD will bring extraordinary plagues on you and your descendants, even severe and lasting plagues, and miserable and chronic sicknesses. He will bring back on you all the diseases of Egypt of which you were afraid, and they will cling to you. Also every sickness and every plague which, not written in the book of this law, the LORD will bring on you until you are destroyed. Then you shall be left few in number, whereas you were as numerous as the stars of heaven, because you did not obey the LORD your God. It shall come about that as the LORD delighted over you to prosper you, and multiply you, so the LORD will delight over you to make you perish and destroy you; and you will be torn from the land where you are entering to possess it.
