Deuteronomy 28:58-62

“If you are not careful to follow all the words of this Law that 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, severe and lasting plagues, and miserable and chronic sicknesses.

And He will bring back on you every disease of Egypt of which you were afraid, and they will cling to you.

Also every sickness and every plague, which are not written in the book of this Law, the Lord will bring on you until you are destroyed.

Then you will be left few in number, whereas you were as numerous as the stars of heaven, because you did not obey the Lord your God.
