When a Sign Leads Astray

Many of us have met someone persuasive enough that we believed them simply because their predictions came true, or because we loved them too much to question them. Deuteronomy 13 anticipates exactly that. Suppose, it says, a prophet or a dreamer gives you a sign, and the sign happens — and then says, 'Let us follow other gods.' Suppose it is your brother, your child, your wife, your closest friend. Suppose a whole town goes over. The chapter's answer is severe, and modern readers rightly feel its weight. It is worth reading slowly and understanding what it is guarding.

Where it sits in the story: In Act 3, Israel is being shaped as a people bound exclusively to one God by covenant. Chapter 12 guarded where they worship; chapter 13 guards whom. The concern with false prophets runs through the whole Old Testament (Jeremiah's struggles with rival prophets are a clear case) and into the New Testament, where Jesus and the apostles warn of false prophets who perform signs.

What this chapter is doing: To declare that no miracle, family tie or majority vote outranks the covenant with God, treating incitement to other gods as the gravest possible betrayal of the community.

• 13:1–5 — If a prophet or dreamer offers a sign that comes true but calls you to other gods, do not listen: God is testing whether you love him with all your heart. That prophet is to be put to death for preaching rebellion against the God who brought you out of Egypt.
• 13:6–11 — If the one who secretly entices you is a sibling, child, spouse or closest friend, do not yield or cover for them. They are to be stoned, with your own hand first, so that all Israel hears and fears.
• 13:12–18 — If report comes that a town has been led into serving other gods, investigate thoroughly. If it is true, the town is devoted to destruction and burned, never rebuilt, and none of its plunder kept — so that God turns from his anger and shows mercy.

Key verse: Deuteronomy 13:3  ·  So what: The penalties here are not a model for any modern state, and Jewish and Christian traditions do not apply them so. What endures is the discernment the chapter demands: impressive signs and close relationships are not proof of truth. Readers are asked what finally holds their loyalty when charisma, family and crowd pull another way.
