Deuteronomy 29:21

18 lest there should be among you man, or woman, or family, or tribe, whose heart turns away this day from the Lord our God, to go to serve the gods of those nations; lest there should be among you a root that bears gall and wormwood;

19 and it happen, when he hears the words of this curse, that he bless himself in his heart, saying, "I shall have peace, though I walk in the stubbornness of my heart, to destroy the moist with the dry."

20 The Lord will not pardon him, but then the anger of the Lord and his jealousy will smoke against that man, and all the curse that is written in this book shall lie on him, and the Lord will blot out his name from under the sky.

21 The Lord will set him apart to evil out of all the tribes of Israel, according to all the curses of the covenant that is written in this book of the law.

22 The generation to come, your children who shall rise up after you, and the foreigner who shall come from a far land, shall say, when they see the plagues of that land, and the sicknesses with which the Lord has made it sick;

23 and that the whole land of it is sulfur, salt, and burning, that it is not sown, nor bears, nor any grass grows therein, like the overthrow of Sodom and Gomorrah, Admah and Zeboiim, which the Lord overthrew in his anger, and in his wrath:

24 even all the nations shall say, "Why has the Lord done thus to this land? What does the heat of this great anger mean?"
