Deuteronomy 30:16-18

And I command you today: Love GOD, your God. Walk in his ways. Keep his commandments, regulations, and rules so that you will live, really live, live exuberantly, blessed by GOD, your God, in the land you are about to enter and possess. But I warn you: If you have a change of heart, refuse to listen obediently, and willfully go off to serve and worship other gods, you will most certainly die. You won’t last long in the land that you are crossing the Jordan to enter and possess.
