Deuteronomy 29:18-21

MLV(i) 18 Lest there should be among you* man, or woman, or family, or tribe, whose heart turns 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 bears gall and wormwood, 19 and it happens, when he hears the words of this curse, that he graces himself in his heart, saying, I will 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 will lie upon him and Jehovah will blot out his name from under heaven. 21 And Jehovah 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.
