This week: Lo Tachmod — the commandment about wanting what your neighbor has
Money & Mitzvot — Week 4
Lo Tachmod — the commandment about wanting what your neighbor has
The 10th commandment is unlike all the others.
The Ten Commandments regulate actions: don't murder, don't steal, don't commit adultery. And then, last on the list, something entirely different.
לֹא תַחְמֹד בֵּית רֵעֶךָ
"Do not covet your neighbor's house… your neighbor's wife, manservant, maidservant, ox, donkey, or anything that belongs to your neighbor." — Shemot 20:14
Not an action. Not even a word. A feeling. The Torah is legislating what goes on inside your head.
That's unusual — strikingly so. Jewish law generally doesn't penalize thoughts. You can think about stealing without violating a prohibition; you violate it when you take the object. So why is desire itself forbidden here?
The Rambam's Answer
The Rambam (Rabbi Moses Maimonides, 12th century) makes a distinction that is one of the most psychologically sophisticated things in all of halacha — Jewish law.
There are actually two formulations of this commandment. In Shemot (Exodus), it says lo tachmod — "do not covet." In Devarim (Deuteronomy), a parallel version uses a different word: lo titaveh — "do not desire."
The Rambam explains the difference this way: Lo tachmod is only violated when desire leads to action — specifically, when you pressure someone to sell you something they don't want to part with, even at a fair price. The covetous desire drove the transaction. Lo titaveh is stricter: it's violated by the desire itself, before any action at all. (The Raavad disagrees — he holds that lo tachmod can be violated by the inner desire itself, even without action. The Rambam’s reading is the more widely followed, but the Raavad’s position is serious.)
The Torah prohibits not just the act that flows from coveting, but the internal orientation of coveting-as-a-way-of-being. It's asking something almost impossibly demanding: to uproot envy at its source.
This Week in Your Family
Teaching It
K–6: This week's story follows Rivka, whose best friend gets a new bicycle with rainbow streamers. Rivka wants one so badly she can't stop thinking about it — and the lesson explores the difference between wanting, needing, and wishing. Core vocabulary: sameiach b'chelko — happy with one's portion, a foundational Jewish value from Pirkei Avot.
High School: Students work through the Rambam's distinction between lo tachmod and lo titaveh directly from the source texts — Shemot, Devarim, and Hilchot Gezelah. The central question: what does it mean that the Torah prohibits an internal mental state? Is this enforceable? Is it even achievable? The chavruta scenarios bring it into contemporary financial life.
Three Questions for Your Table
- The Torah tells us not to covet. But isn't wanting things sometimes a good thing — it motivates us to work hard and improve ourselves? Where's the line between healthy ambition and lo tachmod?
- Think of something you wanted because you saw someone else have it. Did getting it (or not getting it) feel the way you expected? What does that tell you about the nature of wanting?
- The Rambam says lo titaveh is violated by the desire itself — before any action. Do you think it's actually possible to control what you desire? How would you even try?
Living It
Lo tachmod might be the most relevant commandment in the modern economy. Social media is an engineered comparison machine. Lifestyle inflation is what happens when your neighbor's vacation becomes your baseline. "Keeping up with the Cohens" used to be a cliché; now it's the entire business model of Instagram, TikTok, and every aspirational brand on earth.
The practical challenge is distinguishing genuine aspiration from destructive coveting. Wanting to save more, invest better, build something — that's not coveting. That's histapkut, sufficiency-seeking, pointed in a productive direction. Coveting starts when the reference point is someone else's life rather than your own values and goals.
Reflective question for this week: Where in your financial life right now are you making decisions based on what others have rather than what you actually need or value? What would it look like to make that one decision differently?
