Deuteronomy 29:19-21

When such a person hears the words of this oath and they invoke a blessing on themselves, thinking, “I will be safe, even though I persist in going my own way,” they will bring disaster on the watered land as well as the dry. The LORD will never be willing to forgive them; his wrath and zeal will burn against them. All the curses written in this book will fall on them, and the LORD will blot out their names from under heaven. The LORD will single them out from all the tribes of Israel for disaster, according to all the curses of the covenant written in this Book of the Law.
