Deuteronomy 29:19

16 (for ye know how we dwelt in the land of Egypt, and how we came through the midst of the nations through which ye passed;

17 and ye have seen their abominations, and their idols, wood and stone, silver and gold, which were among them);

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

19 and it come to pass, when he heareth 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 Jehovah will not pardon him, but then the anger of Jehovah and his jealousy will smoke against that man, and all the curse that is written in this book shall lie upon him, and Jehovah will blot out his name from under heaven.

21 And Jehovah will set him apart unto 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 And the generation to come, your children that shall rise up after you, and the foreigner that shall come from a far land, shall say, when they see the plagues of that land, and the sicknesses wherewith Jehovah hath made it sick;
