Deuteronomy 29:17-20

17Beware in case there is among you a man or woman, or family or tribe, whose heart turns away today from Adonai our God to go serve the gods of those nations. Beware in case there is among you a root producing poison and bitter fruit.

18“Now when someone hears the words of this oath and in his heart considers himself blessed, thinking, ‘Shalom will be mine, even though I walk in the stubbornness of my heart’—thus sweeping away the moist with the dry—

19Adonai will be unwilling to forgive him. For then the anger of Adonai and His jealousy will smoke against that person. So all the oath that is written in this scroll will settle on him, and Adonai will blot out his name from under the heavens.

20Adonai will single him out from all the tribes of Israel for ­calamity, according to all the oaths of the covenant written in this scroll of the Torah.
