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. And 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, not written in the book of this law, the LORD will bring on you until you are destroyed. (Deuteronomy 28:58-61)
The LORD will smite you with the boils of Egypt and with tumors and with the scab and with the itch, from which you cannot be healed. The LORD will smite you with madness and with blindness and with bewilderment of heart; and you shall grope at noon, as the blind man gropes in darkness, and you shall not prosper in your way; but you shall only be oppressed and robbed continually, with none to save you. (Deuteronomy 28:27-29).
