The Sermon on the Edge

Deuteronomy is delivered on the plains of Moab, to the generation born or grown up in the wilderness, addressed by a Moses who is about to die and will not cross the river with them. Every man of twenty or older counted at Sinai, apart from Caleb and Joshua, has died in the wilderness under the sentence this module's second lesson covered. Deuteronomy exists because that first generation is gone and the covenant has to be re-preached to the people who will actually live under it.

The book's English name comes from a translation accident worth knowing. Deuteronomy 17:18 instructs a future king to write for himself 'a copy of this instruction,' as the BSB renders it, mishneh torah in Hebrew, meaning a second, duplicate copy, not a second, different law. (Torah can mean either 'law' or 'instruction,' and translations differ.) The Greek translators rendered that phrase as to deuteronomion, 'this second law,' and the English title descends from that Greek rendering. The Hebrew title, Devarim, simply means 'Words,' taken from the book's opening line, 'These are the words that Moses spoke.' Deuteronomy is not a new law replacing the one given at Sinai. It is Moses preaching the Sinai covenant a second time, to a different audience, with the urgency of a man who knows this is the only chance he will get to say it.

The book's shape reflects that urgency. After a historical review of the wilderness years, it moves through a long central section of covenant stipulations, then closes with blessings and curses tied to obedience and disobedience, followed by provision for covenant renewal and Moses' death. Scholars of the ancient Near East have long noted that this overall shape, historical prologue, stipulations, blessing and curse, resembles the treaties by which a great king bound a smaller vassal kingdom to loyalty. That resemblance matters for two things this lesson will take up directly: what it means for Israel to 'love' this God, and a genuine scholarly debate over when this book reached the form we now read.

For now, the framing to give students is simple. Everything from chapter 4 onward is a dying man's attempt to make sure a covenant made with people now dead still binds the people about to live. That is the emotional register the whole book is written in, and it is worth reading a page or two of it aloud in that register before analyzing any of its content.

Deuteronomy 4 has Moses reach back to Horeb itself and remind this new generation, most of whom were children at the time, exactly what did and did not happen there: 'You heard the sound of the words but saw no form; there was only a voice.' That absence of a visible form becomes the explicit basis for the prohibition on images that follows: since you saw no form, do not act corruptly by making an idol of any form or shape.

This is the same problem this survey's third module spent an entire lesson on at the golden calf, now stated as direct, retrospective instruction rather than narrated as a failure. The calf was not, this survey argued, primarily an attempt to worship a different god. It was an attempt to make the true God locatable and manageable in visible form. Deuteronomy 4 takes that exact failure and turns it into explicit law: no image, of anything, because the whole revelation at Sinai was built around the deliberate absence of one.

Moses adds a rule about the law itself in verse 2: 'You must not add to or subtract from what I command you.' The covenant is complete as given, not a starting point for supplementation or a target for editing, a claim that later chapters of this book will themselves complicate when they add material Sinai never covered, and that is worth flagging honestly rather than passing over.

Later in the chapter comes a note that will govern chapter 6 as well: 'But if from there you will seek the LORD your God, you will find Him if you seek Him with all your heart and with all your soul.' Wholehearted seeking, not merely correct external behavior, is set up here as the actual substance of covenant loyalty, well before the Shema states it as a command.

Deuteronomy 6:4-5 is the single most recited sentence in Judaism, prayed morning and evening as the Shema, named for its opening imperative, shama, hear. 'Hear, O Israel: The LORD our God, the LORD is One. And you shall love the LORD your God with all your heart and with all your soul and with all your strength.' Even the first sentence carries a genuine translation question, and the BSB flags it in its own footnote. Its main text, with the capital in 'One,' reads as a statement about God's unity. The footnote offers three alternatives: 'The LORD our God is One LORD,' 'The LORD is our God, the LORD is One,' and 'The LORD is our God, the LORD alone.' The last is an exclusive-loyalty claim rather than a strictly numerical one. The Hebrew clause has no verb, so the grammar allows several of these, and the BSB's choice of text does not settle the matter. Both main readings are defensible from the Hebrew, and both fit everything else the chapter goes on to say. The last word of the command, which the BSB renders 'strength,' is the Hebrew me'od, which other translations render 'might' and which points toward 'very much' or 'to the utmost.'

The command that follows, to love God with all your heart, soul, and strength, sounds at first like a demand for an emotion, which raises an obvious question: how can feeling be commanded? A body of research into ancient Near Eastern treaty texts, most influentially William Moran's 1963 study of the language of love in Deuteronomy, has shown that 'love' functions in these chapters as covenant-treaty vocabulary as much as emotional vocabulary. Ancient Near Eastern treaties and diplomatic letters, Assyrian ones prominent among them, use the same language, instructing a subject king to 'love' his sovereign, meaning wholehearted, exclusive political loyalty expressed concretely in service and obedience, not simply warm feeling.

What is broadly settled among scholars is that this treaty background is real and illuminating: Deuteronomy's covenant language draws on a genre its first hearers would have recognized, and 'love' in that genre names allegiance you can observe in someone's actions. What remains genuinely debated, and worth stating to students rather than flattening, is how far to press the parallel. Treaty language explains why love could be commanded at all, but conservative interpreters rightly insist Deuteronomy is not reducible to political metaphor either; the same book that borrows treaty form also describes God's love for Israel in unmistakably affectionate, almost parental terms elsewhere, and expects Israel's love in return to carry real feeling, not obedience alone. Hold both: the command draws on real treaty vocabulary, and it is not only that.

The chapter's own instructions for what to do with this command are concrete rather than abstract: keep these words upon your hearts, teach them diligently to your children, speak of them at home and on the road, tie them as reminders on your hands and bind them on your foreheads, write them on your doorposts and gates. Jewish practice eventually took the hand-and-forehead instruction literally, in the small boxes called tefillin, and the doorpost instruction literally, in the mezuzah fixed to a doorframe. Whether Deuteronomy originally intended those specific physical objects or a vivid figure of speech for total attentiveness is itself debated, but either way the chapter clearly wants covenant loyalty built into the texture of ordinary days rather than confined to occasional worship.

Deuteronomy 30 comes after a long recital of blessings for obedience and curses for disobedience in chapters 27 through 29, and it does something unusual for a covenant document: it anticipates its own future failure. Moses describes a scattering among the nations because of disobedience, and then a return to the LORD and a restoration: 'Even if you have been banished to the farthest horizon, He will gather you and return you from there' (30:4; the BSB's footnote gives the alternative 'to the extremity of the heavens'), said before any of it has happened. A covenant sermon that plans for its own future breach, and for repentance after the breach, is not naive about the people receiving it.

The chapter's most quoted lines insist the covenant is not out of reach: 'For this commandment I give you today is not too difficult for you or beyond your reach.' And then: 'the word is very near you; it is in your mouth and in your heart, so that you may obey it.' Paul later draws on this language in Romans 10:8 and reapplies it to the message of faith in Christ, another instance, like the bronze serpent's use in John 3, of a New Testament writer finding a pattern in the Torah and redirecting it toward something the original text was not directly about. Both readings can be taught; they should not be collapsed into one.

The section closes with the starkest either-or in the book: 'I have set before you life and death, blessing and cursing. Therefore choose life, so that you and your descendants may live, and that you may love the LORD your God, obey Him, and hold fast to Him.' The choice is framed as available and clear, not hidden or requiring special access, which matters given how much of this book has just been spent insisting the commandment is near rather than distant.

Deuteronomy 34 closes the book, and the Torah, with Moses climbing Mount Nebo, to the top of Pisgah, to view the land from a distance, dying there without crossing over, and being buried by God himself in a place, the text says, no one has ever known. The chapter's closing verdict is blunt: 'Since that time, no prophet has risen in Israel like Moses, whom the LORD knew face to face.' It is a fitting close to a book built entirely around Moses' voice, spoken by a man who will not live to see whether his sermon worked.

Centuries later, 2 Kings 22 records a discovery that has shaped how scholars read this book ever since. During temple repairs under King Josiah, around 622 BC, the high priest Hilkiah reports finding 'the Book of the Law' in the temple. It is read to Josiah, who tears his clothes in distress at how far the nation has strayed from what it commands, consults the prophetess Huldah, and then carries out the sweeping reforms described in 2 Kings 23: centralizing sacrifice at Jerusalem, tearing down local high places and their altars, removing mediums and household idols, and keeping a Passover the text says had no equal since the days of the judges.

Church fathers such as Chrysostom and Jerome identified the scroll Hilkiah found with Deuteronomy; W. M. L. de Wette's 1805 dissertation turned that identification into an argument for dating. Since then most critical scholars have identified the scroll Hilkiah found with an early form of Deuteronomy, commonly its legal core in chapters 12 through 26, because Josiah's reforms match this book's distinctive content point for point, especially its insistence on sacrifice at one central place rather than many local ones, a requirement Deuteronomy states for life in the land more sharply than any other Torah law code. On this view Deuteronomy either was composed not long before its discovery, by scribes and priests supporting a reform already underway, or preserved an older legal tradition brought forward and given force at this moment. This became the foundation of the 'D' source in the Documentary Hypothesis and the standard critical dating of Deuteronomy to the seventh century BC.

Traditional and conservative scholarship reads the same chapter differently: Deuteronomy is substantially Mosaic, composed as Moses' own covenant address centuries earlier, and what Hilkiah found in the temple was this genuinely ancient scroll, neglected and nearly forgotten during the long, aggressively idolatrous reign of Manasseh and his son Amon before Josiah, and rediscovered rather than produced. Defenders of an early date also point back to this book's own treaty-like structure, argued to resemble Late Bronze Age Hittite treaties from roughly the same era as Moses more closely than later Near Eastern treaty forms, a case scholars including Kenneth Kitchen and Meredith Kline have pressed. Other scholars respond that the strongest specific verbal parallels, especially in the covenant curses of chapter 28, run closer to Assyrian vassal treaties from the seventh century BC, which would instead support the later date.

What is genuinely settled: 2 Kings 22-23 describes a real found document and a real, extensively documented reform whose content maps closely onto what is distinctive about Deuteronomy, and nobody seriously disputes that correspondence. What is not settled: whether the scroll was Deuteronomy freshly composed for that moment, an ancient Mosaic document recovered after generations of neglect, or an ancient core that continued to develop before reaching the form Josiah's priests found. This remains one of the genuinely open, load-bearing questions in Old Testament introduction, argued by serious scholars on both sides from real evidence, and a class covering it honestly should present it that way rather than declaring the matter closed in either direction.
