Most modern readers know what a law book is supposed to look like. A legislature passes a statute, the statute is divided into titles and sections, and a judge asks what the enacted words require. So when we open Exodus, Leviticus, and Deuteronomy and find long stretches of commands, we instinctively assume that we are looking at an ancient version of the same thing: a biblical law code.

That assumption is so natural that we rarely notice it is an assumption. It shapes what we expect the Torah to do, and then it shapes what counts as a problem when the Torah does something else. If Exodus states a law one way and Deuteronomy states it differently, the modern reader immediately starts looking for an amendment, a contradiction, or perhaps evidence that two rival groups produced competing versions of Israel’s law.

But what if we have brought the wrong kind of law book into the room? The question is not whether the Torah contains laws, because obviously it does. The question is how those laws were expected to function, and here the difference between statutory law and common law changes almost everything.

The Wrong Mental Picture of Biblical Law

Patrick Devlin once gave a particularly helpful distinction between statutory law and common law. Statutory law states the rules in chapters, sections, and paragraphs, and the judge works from the wording of the enacted code. Common law works differently because the judge looks at earlier judgments and asks why the case was decided the way it was.

The old legal term for that reason is ratio decidendi, the reason for the decision. Devlin summarized the difference with unusual clarity: in common law, it is “the principle of the case, not the words” that becomes important. The earlier judgment matters, but its wording is not treated as though every sentence were a statute enacted by a legislature.

Joshua Berman has applied this distinction to biblical law. His argument is not that Israel had no written laws, nor that the commands of God were somehow optional. Rather, the legal collections of the Torah make much better sense when we stop expecting them to operate like a modern statutory code and begin reading them as part of a common-law system.

That distinction also fits a broader view of Torah as something intended to form the life of a people rather than merely regulate isolated conduct. I have approached that larger role of Scripture from another angle in Discipleship as Public Allegiance, where Torah functions as part of Israel’s ordered life under the kingship of God. The legal material belongs inside that larger covenant world rather than standing apart from it as a detached book of regulations.

The Courtroom Clue We Usually Miss

There is a remarkably simple piece of evidence for this common-law approach: ancient judges apparently did not behave the way we would expect judges to behave under a statutory system. Scholars studying Mesopotamian court records have not found a case in which a lawsuit formally cites one of the great ancient law collections. Hammurabi may loom over every introductory textbook on ancient law, but actual judges do not appear in the surviving court records saying the ancient equivalent of, “According to section 23, paragraph 8 of Hammurabi’s Code, the defendant is guilty.”

The same thing happens in the Hebrew Bible. We have several narratives involving legal judgments, but the judges do not settle cases by citing written legal provisions. Solomon’s famous judgment between the two women in 1 Kings 3, for example, contains no appeal to a paragraph in the Torah, even though the entire scene turns on the administration of justice.

That silence fits awkwardly with the assumption that ancient law worked primarily as statutory law. If a written code supplied the governing rule for each case, we would expect the people administering justice to appeal to it at least occasionally. Instead, both Mesopotamian and biblical evidence point toward judges working from established principles, customs, precedents, and a received understanding of justice.

For readers who want the wider Ancient Near Eastern setting, this recent discussion of Laws Older Than Moses? What Ancient Mesopotamia Reveals About the Biblical Laws gives a useful overview of the major Mesopotamian law collections and asks what kind of documents they actually were. The question matters because calling something a “law code” can quietly smuggle our modern assumptions into the ancient world before interpretation has even begun. That is precisely the assumption the common-law model forces us to reconsider.

First, Law Grew Out of a Community’s Moral World

Berman’s first characteristic of common law concerns what German legal theorists called volkgeist, the spirit of the people. The term sounds more mysterious than the idea itself. A society possesses inherited customs, moral expectations, and settled ideas about what justice requires, and judges make decisions inside that moral world.

This means the law is larger than the written formulation of a particular rule. Deuteronomy tells Israel’s judges to judge justly, and it commands the nation to pursue justice. The command assumes that justice is a real thing that must be recognized and worked out, not merely a list of sentences that can be mechanically retrieved from a book.

We still understand something of this instinct. A written rule can address a particular circumstance without exhausting the moral principle behind it. Once the principle is understood, it can be applied to another circumstance that the original wording never mentions.

That helps explain why the prophets can condemn behavior that no Pentateuchal law explicitly describes in the same words. They are not making up a new morality. They are reasoning from Israel’s established moral world and showing what covenant justice requires in a new situation.

Second, Precedent Provides a System of Reasoning

The second characteristic follows naturally from the first. In common law, an earlier decision matters because it establishes a pattern of reasoning. The decision becomes precedent, but the exact words of the earlier judgment do not become a statute that can never be restated.

Berman describes these precedents as forming a “system of reasoning.” That phrase is particularly helpful for reading the Torah because many biblical laws are presented as concrete cases. The reader encounters particular people, particular injuries, particular animals, particular debts, and particular disputes, but the cases teach more than the bare circumstance described.

A case involving one kind of injury can reveal something about responsibility. A law involving property can reveal something about ownership and restitution. A command protecting one vulnerable person can disclose a principle of justice that reaches beyond the original example.

This is why the common-law distinction does not weaken biblical law. In one sense, it does the opposite. A statute can sometimes be evaded by finding a circumstance that falls just outside its wording, but a legal principle follows you out the door because the question becomes not simply, “Does this exact sentence mention what I did?” but, “What kind of justice does this law establish?”

Third, Law Can Develop as Circumstances Change

This brings us to one of the great difficulties in reading biblical law. Exodus and Deuteronomy sometimes address similar subjects differently, and modern readers naturally want to know which version is the real one. If we assume statutory law, the problem can become severe because a later statute normally amends, repeals, or replaces an earlier statute.

Common law does not require that conclusion. The Covenant Code appears early in Israel’s covenant life, while Deuteronomy addresses Israel on the edge of the land after a generation of wilderness experience. Changed circumstances can produce a fresh formulation of an established legal principle without declaring the older formulation false.

The later law can interpret the earlier one, extend it, narrow its application, or work out its implications under new conditions. The two formulations can therefore differ without functioning as rival constitutions. Their relationship may be closer to continued legal reasoning than legislative warfare.

This is one reason Berman’s work has become significant in discussions of apparent inconsistencies in the Torah. For a fuller presentation of his argument and its implications for Pentateuchal criticism, the OnScript conversation Joshua Berman — Inconsistency in the Torah is worth hearing. Once the common-law possibility is admitted, difference between legal collections no longer automatically means that one writer was trying to overthrow another.

That observation reaches into the larger question of how we think about biblical composition. My discussion of Was Isaiah Written by One Author? The Unity of Isaiah Explained deals with a related problem: modern theories can sometimes turn genuine differences in setting, form, and emphasis into evidence of literary conflict too quickly. Difference requires explanation, but difference by itself does not tell us what kind of relationship exists between two texts.

Fourth, Legal Wisdom Can Come From More Than Laws

The fourth characteristic may be the most important for actually reading the Bible. If Israel operated within a common-law culture, then judges and prophets were not limited to formal legal collections when reasoning about justice. Narratives, proverbs, customs, parables, inherited sayings, and other forms of folk wisdom could all preserve the moral reasoning of the community.

That makes sense of the Torah itself because the Torah stubbornly refuses to become the kind of book modern categories sometimes want it to be. Genesis through Deuteronomy mixes stories with commands, genealogies with rituals, speeches with lawsuits, historical memories with legal cases. If law can be communicated through precedent and communal wisdom, that mixture is not disorder.

The narrative portions can teach justice just as surely as the legislative portions can. A story can show what faithfulness looks like under pressure. A judgment can establish a precedent, and a proverb can condense a moral norm into a sentence memorable enough to survive for generations.

This broader understanding also helps explain why Nehemiah 8 presents Torah as something that orders worship, memory, celebration, grief, and community life rather than merely forbidding certain behaviors. I explore that point more fully in Nehemiah 8: Why Restoration Needs the Word of God. Torah forms a people, and legal reasoning belongs inside that larger work of formation.

Isaiah Shows Us What This Kind of Legal Reasoning Looks Like

Isaiah 5 gives us a remarkable example because the chapter functions as a lawsuit against Judah without turning into a string of legal citations. Isaiah opens with a song about a vineyard. The owner did everything reasonably expected of him, yet the vineyard produced worthless fruit, so Isaiah asks his audience to judge between the owner and the vineyard.

The trap is similar to Nathan’s parable before David. Isaiah gets his audience to recognize the justice of the case before revealing that they themselves are the vineyard. A story drawn from ordinary agricultural life becomes a legal argument because it awakens the community’s own sense of justice.

Isaiah then condemns wealthy people who join house to house and field to field until they stand virtually alone in the land. The accusation overlaps with the Jubilee legislation of Leviticus 25, but Isaiah does not quote the Jubilee law and then perform an exegesis of its wording. He takes the principle behind Israel’s land law—the protection of families and the restraint of acquisitive power—and brings that principle against the economic practices of his own generation.

Later, Isaiah attacks people who call evil good and good evil. There is no Pentateuchal statute that reads exactly like Isaiah 5:20, yet the accusation is unmistakably legal and moral. The distinction between good and evil runs through Israel’s stories, wisdom literature, prophetic preaching, and judicial ideals, so Isaiah can prosecute the offense without producing a statutory citation.

Then, near the end of the chapter, Isaiah condemns those who accept bribes and deny justice to the innocent. Here his language touches principles found in both Exodus and Deuteronomy. Under a statutory model, movement between supposedly competing legal traditions can look suspicious, but under common law it is precisely what we should expect: Isaiah draws freely from Israel’s legal inheritance because the collections provide a shared system of reasoning.

That is why Isaiah can conduct a legal prosecution without sounding like a lawyer reading numbered clauses from a code book. He uses a vineyard story, community morality, proverbial wisdom, principles drawn from different legal collections, and the ethical logic behind particular commands. Yet at the end he can still say that Judah has rejected the torah of Yahweh.

What This Does to the “Contradictions” in Biblical Law

Once we see the distinction, many familiar problems look different. Modern interpreters compare two legal texts, notice that the wording is different, and conclude that the laws contradict one another. Sometimes the difference is real, but the conclusion depends on the assumption that both texts were intended to function as statutes in a closed statutory code.

Under common law, variation may be exactly what legal development looks like. An earlier formulation remains authoritative while a later formulation works out the principle for another generation, another place, or another social circumstance. The later text does not have to pretend that the earlier text never existed because both belong to the same continuing legal conversation.

This does not make every difference disappear, nor should it. It changes the question we ask about the difference. Instead of beginning with, “Which code replaced the other?” we can ask, “What principle does each formulation preserve, and why does that principle take a different legal form here?”

That question is historically better suited to the evidence we actually possess. It also allows the Torah to behave like the kind of legal literature ancient Israel appears to have produced rather than forcing it to behave like legislation drafted for a modern government. The result is not an easier Torah, but a more coherent one.

How Common Law Changes the Way We Read Torah

The practical change is fairly simple. When we encounter biblical law, we should certainly read the words carefully, but we should not stop with the wording. We should ask what situation the law addresses, what injustice it restrains, what good it protects, and what principle of judgment the case establishes.

Then we should trace that principle through the rest of Scripture. We should watch how narratives embody it, how wisdom literature states it, how prophets apply it, and how later legal formulations develop it. The Torah begins to look less like an accumulation of disconnected regulations and more like an extended education in the justice of God.

BibleProject’s Biblical Law offers a useful introduction to that broader purpose of biblical law. Its emphasis differs from the common-law argument developed here, but the basic instinct is compatible: the hundreds of commands in the Torah belong to a larger theological and moral project rather than functioning as an ancient checklist detached from Israel’s story. That larger frame also helps us understand why legal texts, narratives, and prophetic indictments can all participate in the same moral world.

And this is where the common-law approach finally becomes more than an interesting theory about ancient jurisprudence. It teaches us to look through the legal case toward the justice being expressed through it. The command remains important, but the command also trains the reader to reason about righteousness.

The Torah Was Never Trying to Be the U.S. Code

Perhaps the strangest thing about the modern debate over biblical law is how often the Torah is judged for failing to behave like a kind of literature that would not exist for thousands of years. We expect comprehensive coverage, exact harmonization, legislative supersession, and judicial citation, and then we become suspicious when the ancient evidence does not cooperate. The problem may lie less in the Torah than in the legal assumptions we carried into it.

Biblical law makes considerably more sense when read within the world of common law. Community norms matter, precedents establish patterns of reasoning, legal formulations develop as circumstances change, and stories and proverbs can teach justice alongside written commands. Those four features explain a great deal about the strange texture of the Torah.

So was biblical law really a “law code”? Not in the modern statutory sense that most readers instinctively imagine when they hear those words. The Torah is legal literature, but we understand its legal character better when we stop demanding that Moses sound like Congress and begin listening to the kind of legal reasoning ancient Israel actually practiced.
