Deuteronomy 29:18-19

18lest 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; 19and 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.
