Ki Tetze — The Fence on the Roof, the Bird's Nest, and Laws That Don't Sound Spiritual But Are

Taking Responsibility Before the Accident Happens

So much of this Torah portion deals with the texture of ordinary life rather than formal religion. Take Deuteronomy 22:8 — the command to build a fence around the roof of your house. The principle behind it is simple but profound: take responsibility for your action before an accident happens, not after. It's a command about foresight and prevention, not ritual.

The same impulse shows up in the law protecting a mother bird:

This law was given by God to Israel long before there was any cultural sensitivity to nature or ecology. And the modern data makes the wisdom of it almost eerie: according to the 2019 Global Assessment Report on Biodiversity and Ecosystem Services, the biomass of wild mammals has fallen by 82 percent, natural ecosystems have lost about half their area, and roughly a million species are at risk of extinction — largely from human action. At least 571 species have been lost since 1750. The Torah is at least 3,250 years old, and it already understood that careless destruction of breeding populations costs you in the long run.

A Law on the Books of Israel Today

Deuteronomy 22:1-4 instructs that if you see your brother's ox or sheep wandering, you cannot look away — you must bring it back, or if you don't know the owner, take it to your own house and care for it until they come looking. This is the direct legal ancestor of the Good Samaritan story, and remarkably actually exists as real law on the books of the modern State of Israel today, named explicitly "The Good Samaritan Law." And this principle of caring for what belongs to another, even an adversary, extends to every gentile believer who has been "grafted into the natural olive tree" and added to the commonwealth of Israel through Yeshua (see Ephesians 2:10-13). It is not a Jewish-only ethic; it belongs to everyone who has been brought into this covenant family.

I lived in the United States from 1962-1964 and 1967-1969 — in South Georgia, in Miami, in Rochester, Michigan, and in Nashville, Tennessee. From my experience, most of the Christians I knew in Rochester, Miami, and Nashville would not even get close to their neighbor's cat or dog, much less a donkey or a goat. The only place I lived where I could imagine this command actually being observed was Dasher, Georgia — a small, homogeneous community of German Christian descendants near the Florida border, so intermarried they were practically one extended family. There, in the 1960s, I believe this law would have been kept. As for today, I have my doubts — though I would be happy to be corrected by the Coplands and Hams and Wisenbakers of that community.

The Firstborn's Right Cannot Be Bought or Bargained Away

This week's text also contains one of the most quietly radical inheritance laws in the ancient world:

In other words, a father's personal feelings cannot override an objective legal right. Today in the Christian world two wives are not permitted at all, and in the Jewish world the rabbis allow it only under the most extreme circumstances — for instance, if a man has small children and his first wife is hospitalized with a prolonged mental illness that makes divorce impossible. But the underlying principle still applies powerfully today: a parent's preference for one child over another, however natural it might feel, has no business determining what is rightfully owed.

Scripture itself shows us the cost of ignoring this principle. Rebecca preferred Jacob over Esau — and thousands of years later, the descendants of Esau are still in conflict with the descendants of Jacob. Jacob himself repeated the mistake, preferring Joseph over his eleven other sons — and the resulting hatred nearly destroyed the family. God can use our mistakes and bring good out of our weaknesses, but there is still always a price paid for ignoring God's instruction about equal treatment. And it isn't only an ancient problem — today, in the name of personal freedom, there are wealthy men in the modern West who leave their entire estate to a mistress or lover rather than to their legal wife and children, exactly the kind of partiality this text was written to prevent.

A Whole Catalogue of Daily-Life Commands

This portion is dense with instructions that don't sound spiritual on the surface but govern the texture of a healthy society: laws regulating incest, connected directly to a real case Paul addresses in 1 Corinthians 5 of a church member involved with his mother-in-law; the rule that a non-Israelite slave who runs away from his master must not be caught and returned, on the principle that no one runs away from something good — if he ran, his master must not have treated him right; the requirement of a clear distinction between the sexes in Deuteronomy 22:5; instructions about not mixing things that don't naturally belong together; rules for keeping a community spiritually and physically clean. The Torah deals overwhelmingly with real, daily, textured human life — not abstract religious ritual.

We must remember the words of the prophets in Isaiah 1, Jeremiah 7, and Hosea 6, and the words of Paul to the philosophers of Athens:

Religion has a tendency to seal up this fountain of fresh water under heavy dogmatism. The Torah's instinct is the opposite: to keep faith embedded in the texture of real life.
