Deuteronomy 28:59-62

59he will bring wondrous plagues on you and your descendants, severe and lasting plagues, and terrible and chronic sicknesses.

60He will afflict you again with all the diseases of Egypt, which you dreaded, and they will cling to you.

61The Lord will also afflict you with every sickness and plague not recorded in the book of this law, until you are destroyed.

62Though you were as numerous as the stars of the sky, you will be left with only a few people, because you did not obey the Lord your God.
