Deuteronomy 29:19-21

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. 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. 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.
