In Judaism, the value of human life is nearly supreme; preserving life even overrides strict laws such as the observance of Shabbos and fasting on Yom Kippur.
This value extends beyond emergency situations; the Torah mandates a comprehensive approach to health and safety in general:
וְנִשְׁמַרְתֶּם מְאֹד לְנַפְשֹׁתֵיכֶם – Take great care of your souls… (4:15)
It is worth highlighting that the Torah is uncharacteristically emphatic here. In the Torah’s approach to language, words are measured, and adverbs are rarely used; the use here signals a profound emphasis on the importance of personal safety and caution. It’s not just important, but very important – מְאֹד.
One specific law that tangibly encapsulates Judaism’s deep regard for life and safety is the simple commandment to build a guardrail around a roof, preventing potential tragedy:
כִּי תִבְנֶה בַּיִת חָדָשׁ וְעָשִׂיתָ מַעֲקֶה לְגַגֶּךָ וְלֹא תָשִׂים דָּמִים בְּבֵיתֶךָ כִּי יִפֹּל הַנֹּפֵל מִמֶּנּוּ – When you build a new house, you shall make a guardrail for your roof, so that you shall not bring blood upon your house if anyone falls from it. (22:8)
While legal nuances and practicalities indicate that not everyone practices this law and that there are physical instances where building a fence is impossible or unnecessary, the moral imperative underlying the law is always operative. Our general orientation should be that we take practical and pragmatic precautions to do what we can to prevent danger and bloodshed, particularly in our own homes.
But we believe in an immanent Creator, that everything that happens is divinely ordained, or as our sages put it, a person does not injure his finger below unless it was first decreed above.
To put it in philosophical and theological terms, if God is omnipotent, omnipresent, and omniscient, then whatever happens in this world to individuals, life’s great and small wins and losses, are solely the product of Divine will, and resistance is futile.
So why build a fence to prevent accidental falls? If a person is supposed to fall, so the thinking goes, then protective measures will not prevent the fall, nor will their absence cause injury to someone the Creator miraculously spares!
You can’t fight fate; why take precautions at all, then?
The Sefer HaChinuch uses this law to reveal a much broader point; part of the order of Creation is that Divine Will manifests to us as the laws of nature to which we are subject, which is why we build fences rather than count on miracles.
This explanation has far-reaching implications: God has created this world and guides it according to laws of nature that are predictable, comprehensible, and, for the most part, binding. There might be exceptions, but there are rules that hold true for all people in all places, and the primary way humans experience Divine Providence is by navigating these natural laws. Part of how we experience that is that fire burns, and water extinguishes fire. Similarly, the laws of nature dictate that gravity makes things fall and that when a person falls from a tall roof to the ground, they will be seriously injured or die. Accidents happen, so the Torah commands us to act prudently and build fences to guard our surroundings.
Just as we visit a doctor when sick rather than waiting for a miracle, building a guardrail is an expression of engaging with the world responsibly, acknowledging that God’s providence often operates through natural means.
It follows that our sages understood this commandment to extend far beyond the physical act of constructing a guardrail, instead representing a broader category of obligation to protect ourselves and others from harm, obligating individuals to remove dangerous hazards, whether a loose stone or an open well, emphasizing our responsibility for the safety of our surroundings.
The Rambam expands this obligation to prohibit any form of dangerous behavior, such as keeping a dangerous dog or using a rickety ladder; there is no difference between a roof and any other hazard, whether it’s riding a bike, or carrying a knife, each must be made safe.
It also follows that this can be understood more broadly not just as a directive to guard physical health but also to protect spiritual and emotional well-being as well, guiding us to avoid harmful actions, behaviors, toxic environments, and spiritual dangers.
We are constantly building in our lives, and everything we build needs boundaries. Relationships need fences to ensure mutual respect and growth. Everyone needs boundaries to protect against the distractions and temptations that so easily threaten our spirituality.
It is easy to take liberties with the dignity, honor, or feelings of the people we love. At times, we do things that are hurtful, insensitive, and demeaning. Boundaries are the fences that ensure that we behave properly. Negligence in erecting a fence around an exposed roof invites physical danger and is a cause for monetary and even criminal liability; failing to set other boundaries can similarly invite harm in less obvious ways.
The Lubavitcher Rebbe highlights how the Torah emphasizes this law specifically with new construction because moments of novelty are when people are most susceptible to missing critical safety measures. When we are swept up in the excitement of something new, whether it’s a new home, child, business venture, job, relationship, car, or bicycle, we often overlook the safeguards necessary to prevent harm. The Lubavitcher Rebbe emphasized the importance of setting boundaries and guardrails with every new initiative. It is folly and the height of naivete to freestyle and hope for the best. Take the precautionary steps of establishing boundaries and putting measures in place to protect what’s valuable.
While Judaism does believe in destiny and fate to some extent, we equally also believe in our ability to influence and change it – תְּשׁוּבָה וּתְּפִלָּה וּצְדָקָה מַעֲבִירִין אֶת רֹעַ הַגְּזֵרָה.
The mitzvah of building a fence around the roof is a constant reminder that, while we may believe in destiny, we are not mere bystanders in our own lives. Our role is not to surrender passively to fate but to shape the conditions of our existence actively. Even if, God forbid, someone is destined to fall, our responsibility is to ensure that we are not the cause of that fall – וְלֹא־תָשִׂים דָּמִים בְּבֵיתֶךָ.
Maybe someone is destined to fall. Maybe something bad is supposed to happen. But you don’t have to make it easy. You certainly don’t have to be the one that makes it happen. Statistics are real, but with precautions, they can be things you hear about, not things you are a part of.
The mitzvah of building a fence teaches us that it is not enough to hope for the best; we must take deliberate, thoughtful actions to create safe and nurturing environments.
While we can’t control everything, we can control whether we wear a seatbelt, use a turn signal, or let children ride a bike without a helmet.
Remember, boundaries aren’t just physical barriers; they are the thoughtful choices we make to protect what is valuable to us.
If you care about something, protect it, because better safe than sorry.
