Mishneh Torah, Sabbath 28

Hook

Have you ever wondered where exactly a city "ends"? On the Sabbath, Jewish tradition limits how far you can travel outside your home—a boundary known as the Techum. But if you live in a house just outside the city walls, or in a village nearby, do you have to stay stuck in your living room while your neighbors wander into town? It feels like a silly, technical question, but it’s actually a beautiful way to think about community. Rambam (Maimonides) teaches us that "city limits" aren't just cold, hard stone walls; they are about connection. If a house is close enough to be part of the pulse of the city, it’s not just a lonely outpost—it’s home. Today, we’ll explore how these ancient, quirky rules turn a collection of scattered buildings into one big, unified neighborhood.

Context

• Who: This text is by Maimonides (Rambam), a legendary 12th-century scholar and doctor who wrote the Mishneh Torah, a massive "how-to" guide for Jewish life.
• When/Where: Written in Egypt during the Middle Ages, this section specifically deals with the laws of the Sabbath—a day of rest where travel is physically restricted.
• Key Term: Cubits – An ancient unit of measurement based on the length of a human forearm, roughly 18–24 inches.
• The Big Picture: In the Mishneh Torah, Sabbath 28 Mishneh Torah, Sabbath 28, Rambam explains how to mathematically map out your "legal" range for walking on the Sabbath, ensuring that neighbors are counted as part of the community.

Text Snapshot

"Whenever there is a home that is outside a city, but seventy and two thirds cubits... or less from the city, it is considered to be part of the city and joined to it. When two thousand cubits are measured in all directions from the city, this house [is considered to be on the extremity of the border] and the measurement [begins] from there."

— Mishneh Torah, Sabbath 28:1

Close Reading

Insight 1: Proximity Creates Belonging

Rambam’s logic is both mathematical and deeply relational. He suggests that if a house is within roughly 70 cubits (about 100–120 feet) of a city, it isn’t "outside" anymore. In the eyes of the law, it is "joined" to the city. Think about your own street. We often think of our home as an island, but Rambam is arguing that we are defined by our proximity to our neighbors. If you are close enough to walk to the city, you are part of the city's identity. This teaches us that community isn't just about who lives inside the "walls"; it's about who is within reach. By defining these tiny, specific distances, the law ensures that no one is left stranded or "outside" the community map just because their front door sits a few yards past a theoretical line. It is a legal way of saying, "You are one of us."

Insight 2: The Geometry of Inclusivity

Rambam doesn't just treat the city like a square box; he accounts for the messy reality of geography. He talks about cities on rivers, crescent-shaped villages, and valleys that are hard to measure. When he discusses how to handle a mountain or a deep crevice, he doesn't tell us to give up or stay home. He gives us instructions on how to "approximate" the distance. This is a profound shift in mindset. Instead of forcing the world to fit into a perfect, rigid grid, he provides tools to include the irregular parts of our lives. If there’s a valley, measure the span. If there’s a wall, account for the thickness. The goal is always to include as much as possible, not to exclude or strictly limit. Even for things as abstract as "city limits," the law bends toward connection.

Insight 3: Trusting the "Expert" and the "Child"

In the final verses of the chapter, Rambam notes that if there is a conflict about where the boundary lies, we should lean toward the more "lenient" or larger measurement. He even says we should trust the memory of someone who says, "I remember walking this far when I was a child." This is beautiful because it prioritizes the lived experience of the community over a cold, bureaucratic map. By valuing the memory of an elder or the observation of a servant, Rambam is reminding us that the "truth" of a community's boundaries is actually held in the people who live there. We aren't just following rules on a page; we are honoring the shared history and the practical reality of how people actually walk and live in their space.

Apply It

This week, practice the "70-cubit rule" of awareness. Once a day, step outside your home and look at your immediate neighbors. Instead of just seeing them as people who live next door, take 60 seconds to visualize the invisible lines that connect your home to theirs. Think of one way you can make your home feel more "joined" to your block—maybe it’s a quick wave, a plant on the porch, or simply acknowledging that your "city" starts at their front door too. It’s a tiny reminder that we are all part of a larger, interconnected web.

Chevruta Mini

1. Rambam says that being "close" (70 cubits) makes you part of the city. In your own life, what makes you feel like you truly "belong" to a group or a community? Is it distance, shared habits, or something else?
2. The text suggests that when we are unsure about boundaries, we should choose the "lenient" path that includes more people. Why do you think Jewish tradition prioritizes inclusion over strict limitation in this case?

Takeaway

Remember this: Your community isn't defined by rigid walls, but by the intentional effort to keep your neighbors within reach.
