Arukh HaShulchan, Orach Chaim 316:25-31
Hook
On Shabbat, we strive for a state of cosmic harmony—a temporary return to Eden where humanity ceases its aggressive dominion over the natural world. But what happens when that natural world crawls, flies, or slithers into our living spaces, threatening our comfort or even our lives?
The Arukh HaShulchan reveals that the boundary between a holy day of rest and a desperate struggle against pests is not merely a practical nuisance, but a profound legal and philosophical battleground over what constitutes "creative mastery" over the animal kingdom.

Context
To appreciate the genius of Rabbi Yechiel Michel Epstein (1829–1908) in his monumental code, the Arukh HaShulchan, we must contrast his historical and literary environment with that of his contemporary, Rabbi Yisrael Meir Kagan (the Chafetz Chaim), author of the Mishnah Berurah.
Writing in Novogrudok, Belarus, Rabbi Epstein was an active communal rabbi (rav d'shachra) who sat on the front lines of daily human dilemmas. While the Mishnah Berurah represents a highly analytical, often stringent compilation of preceding authorities designed to establish a singular defensive line around the law, the Arukh HaShulchan seeks the organic, flowing pulse of the Talmudic sugya (topic). He consistently champions the koach d'heteira (the power of leniency), striving to align the formal demands of Halakha with the lived reality of ordinary people.
The topic at hand is the melacha (prohibited creative labor) of Tzeidah (trapping), one of the 39 primary labors forbidden on Shabbat. The historical anchor for this prohibition lies in the construction of the Tabernacle (Mishkan), where rams and the mysterious tachash were trapped to use their skins for the sacred coverings, as recorded in the Talmud Talmud Shabbat 73a.
In these paragraphs of Orach Chaim 316, Rabbi Epstein tackles the messy reality of trapping small, non-domesticated, and often hostile creatures: flies, fleas, wasps, snakes, and scorpions. He asks a fundamental question: When does protecting oneself from pain or danger cross the line into the forbidden act of subjugating a creature of the wild?
Text Snapshot
The following passage from Arukh HaShulchan, Orach Chaim 316:25-31 serves as our anchor. You can view the complete bilingual text on Sefaria.
Arukh HaShulchan, Orach Chaim 316:25
"כל שבמינו ניצוד, פירוש: שדרך בני אדם לצוד אותם לעורותיהם או לבשרם או לשחק בהם... הצד אותם בשבת חייב חטאת. אבל כל שאין במינו ניצוד, כמו זבובים ופרעושים ויתושים וכיוצא בהם... הצד אותם פטור אבל אסור..."
“Any creature whose species is trapped—meaning, it is the way of people to trap them for their skins, their meat, or to play with them... one who traps them on Shabbat is liable for a sin-offering. But any creature whose species is not trapped, such as flies, fleas, mosquitoes, and the like... one who traps them is exempt from biblical liability, but it is rabbinically forbidden...”
Arukh HaShulchan, Orach Chaim 316:27
"נחשים ועקרבים וכל חיה רעה שנושכים וממיתים, מותר להרגן בשבת אפילו אינם רצים אחריו... ואם אינם ממיתים אלא מזיקים ומכאיבים, אסור להרגן אלא אם כן רצים אחריו... אבל לצודן, כגון לכפות כלי עליהם שלא ישכוהו — מותר בכל עניין..."
“Snakes, scorpions, and any wild beast whose bite is lethal may be killed on Shabbat, even if they are not actively chasing a person... But if they are not lethal, only causing damage and pain, it is forbidden to kill them unless they are chasing him... However, to trap them, such as placing a vessel over them so they do not bite, is permitted in all circumstances...”
Close Reading
To unlock the depth of these paragraphs, we must analyze them through three distinct lenses: the structural taxonomy of the Arukh HaShulchan's argument, the precise conceptual mechanics of his terminology, and the underlying existential tension between human suffering and the cosmic order of Shabbat.

1. Structural Architecture: The Taxonomy of Trapping
The Arukh HaShulchan does not merely list laws; he constructs a highly organized, layered taxonomy of animal life based on human utility, intent, and threat. If we look closely at paragraphs 25 through 31, we can see that his legal matrix is built upon three intersecting axes:
- The Nature of the Species (Minim Hanitzodim vs. She'ein Minim Hanitzodim): In paragraph 25, Rabbi Epstein establishes the baseline biblical definition of Tzeidah. The Torah only prohibits trapping when the animal belongs to a species that is traditionally hunted for its resources (meat, hide, or commercial value). This distinction is anchored in Talmud Shabbat 106b. When you trap a deer, you are performing a biblically prohibited labor (melacha d'oraita). When you trap a fly, which has no commercial or culinary value, you are performing an act that is only rabbinically prohibited (shevut). This structural distinction is crucial because it opens the door for legal leniency when human pain enters the equation.
- The Severity of the Threat (Mortal Danger vs. Pain vs. Annoyance): In paragraphs 26 and 27, the text shifts from the utility of the animal to its impact on the human being. Rabbi Epstein categorizes pests into three groups:
- Lethal threats (e.g., venomous snakes or scorpions): Here, the overriding principle of Pikuach Nefesh (saving a life) suspends all Shabbat laws. You may trap or kill them outright.
- Painful but non-lethal threats (e.g., wasps, hornets, or biting fleas): These creatures cause genuine physical suffering (tza'ar).
- Mere annoyances (e.g., standard houseflies or non-biting gnats): These cause irritation but not actual physical trauma.
- The Spatial Mechanics of the Trap: In paragraphs 30 and 31, the Arukh HaShulchan moves from biology to physics. He examines the physical boundaries of what constitutes a "trap." Is closing a window or a book with an insect inside considered trapping? He demonstrates that the definition of Tzeidah requires a reduction of space so significant that the animal can be captured in a single grasp (b'achiza achat). If the space remains large (like a room or a house), the animal is not halakhically "trapped," even if its escape to the outdoors is blocked.
2. Key Terminology and Conceptual Mechanics
To read this text with true fluency, we must master the conceptual machinery that Rabbi Epstein utilizes to navigate these cases.
Melacha She'eina Tzricha Legufah (A labor not needed for its own sake)
This is one of the most important concepts in the laws of Shabbat, originating in a monumental debate between Rabbi Yehuda and Rabbi Shimon in Talmud Shabbat 31b.
A melacha she'eina tzricha legufah occurs when a person performs a prohibited physical act, but does not want or need the primary, constructive outcome of that act as it was performed in the Tabernacle.
In the Tabernacle, animals were trapped because the builders wanted the animals (for their skins). If you trap a scorpion because you want to keep it as a pet or use its venom, that is a melacha tzricha legufah (a labor performed for its own sake).
But if you trap a scorpion simply because you are terrified of being stung, you do not want the scorpion itself; you want the absence of its threat. You are trapping it to protect yourself.
According to Rabbi Shimon, whose opinion we rule by in rabbinic law, a melacha she'eina tzricha legufah is biblically exempt (patur) but rabbinically forbidden (assur).
The Arukh HaShulchan uses this rabbinic status as a legal lever in paragraph 27: because trapping the painful pest is only a rabbinic prohibition (due to it being she'eina tzricha legufah), and because rabbinic prohibitions can be waived to prevent significant pain or bodily harm (tza'ar), one is permitted to place a cup or vessel over a painful insect on Shabbat.
Davar She'eino Mitkaven vs. Pesh Reishei
In paragraph 31, Rabbi Epstein addresses a common household dilemma: closing a window or door when there are flies or mosquitoes in the room. When you close the window to keep the cold air out, you are also inevitably trapping the flies inside.
- Davar She'eino Mitkaven (an unintentional act) occurs when you perform action A (closing the window) for a permitted purpose (keeping warm), and action B (trapping the flies) might happen, but it is not your intention. In general, an unintentional act is permitted on Shabbat.
- Pesh Reishei (an inevitable consequence) occurs when action B is guaranteed to happen as a result of action A. If you close the window, the flies will be trapped. The Talmudic rule in Talmud Shabbat 75a states that even if you don't intend for the consequence to happen, if it is inevitable, it is treated as if you did it intentionally.
- Pesh Reishei d'lo nicha lei (an inevitable consequence that you do not care about): Rabbi Epstein notes that you have absolutely no interest in trapping these flies; in fact, you would prefer they flew away. Because this is a pesh reishei on a rabbinic prohibition (since trapping flies is only rabbinic) and it is entirely undesirable (lo nicha lei), the Arukh HaShulchan finds room for leniency, allowing one to close doors and windows normally without worrying about the insects inside.
3. The Inner Tension: Human Suffering vs. The Shabbat Rest
Behind this intricate legal grid lies a deep, humanistic tension. The laws of Shabbat are designed to protect the sanctity of the day, demanding that we step back from controlling our environment.
A rigorous, purely formalist reading of these laws might suggest that if trapping is forbidden, a person must simply endure the pain of a biting flea or the terror of a crawling insect on Shabbat. The holiness of the day, under this view, demands human passivity and sacrifice.
However, the Arukh HaShulchan rejects this paralyzing formalism. For Rabbi Epstein, the Torah was given to living human beings, and the Shabbat was designed for delight (oneg), not torment.
Look closely at paragraph 26, where he discusses the flea (par'osh). The Shulchan Aruch in Shulchan Aruch, Orach Chaim 316:9 rules that one may not trap a flea unless it is actively biting.
The Arukh HaShulchan unpacking this ruling does not treat it as a cold mathematical formula. He analyzes the psychological reality of a person suffering from an insect bite.
He notes that if the insect is causing pain, the human body's natural defensive reaction is not a rebellion against Shabbat, but a basic biological need. By framing the removal of the pest as an act of self-defense rather than an act of predatory trapping, he aligns the physical reality of human suffering with the spiritual integrity of the day.
Two Angles
To deepen our understanding, let us contrast the approach of the Arukh HaShulchan with that of his contemporary, the Mishnah Berurah, on the specific issue of closing a chest or a window when flies are present (the classic case of pesh reishei in trapping).

└────────────────────────────────────────┴────────────────────────────────┘
Angle 1: The Formalist/Defensive Paradigm (Mishnah Berurah)
The Mishnah Berurah Mishnah Berurah 316:45 takes a highly cautious, defensive posture. He rules that if you want to close a chest or a book, and there are flies inside, you must be extremely careful. If closing it will inevitably trap them, you are forbidden from doing so unless you first chase the flies away.
The Mishnah Berurah focuses on the objective, physical result of the action: the moment the lid closes, the flies are trapped, and a rabbinic boundary has been breached. He prioritizes guarding the formal boundaries of the melacha, demanding that the individual constantly monitor their physical surroundings to prevent any accidental trapping.
Angle 2: The Functionalist/Realistic Paradigm (Arukh HaShulchan)
The Arukh HaShulchan Arukh HaShulchan, Orach Chaim 316:30-31 presents a radically different, functionalist reading. He argues that closing a door, a window, or even a large chest is not fundamentally an act of "trapping" because the primary function of these actions is to secure the house or protect the contents of the chest.
Furthermore, he points out the absurdity of requiring people to inspect every corner of their doors and windows before closing them. Rabbi Epstein argues that since a house or a room is a large space where the flies can still move around freely, it does not meet the halakhic definition of a "trap" (tzeidah).
He writes that we must look at the human context: the person is simply living in their home, and the incidental containment of insects in a large space is completely irrelevant to the spirit and the letter of the law of trapping.
Practice Implication
How does this halakhic debate shape our daily lives and practical decision-making on Shabbat today? Let us translate the Arukh HaShulchan's late-19th-century principles into a clear, modern action plan for common household scenarios.

prevent stinging. (Tza'ar) ignore it. (No Tza'ar) let it escape naturally.
Scenario A: A Wasp or Hornet Enters the Shabbat Kiddush
Imagine a wasp flying around a table filled with children. The wasp is not deadly to most people, but its sting is highly painful (tza'ar), and for someone with an allergy, it could be lethal (pikuach nefesh).
- According to the Arukh HaShulchan: Because the wasp causes real physical pain, trapping it is classified as a melacha she'eina tzricha legufah on a species that is not hunted (a double rabbinic level).
- The Action: You are fully permitted to place a cup, bowl, or container over the wasp to trap it and prevent it from stinging anyone. You may also do this to a biting insect like a flea or mosquito if it is actively causing distress.
Scenario B: A Harmless but Unsettling Spider or Beetle on the Wall
You see a large, harmless spider crawling on the wall near your bed. It does not bite or sting, but it causes you emotional discomfort or disgust.
- According to the Arukh HaShulchan: Because the spider is entirely harmless, it does not fall into the category of a painful threat (makh'iv). Therefore, you cannot trap it under a cup, as that would violate the rabbinic prohibition of trapping.
- The Action: You may not trap it or kill it. However, if its presence is causing severe psychological distress (which some halakhic authorities equate to tza'ar), you may gently brush it away using an indirect method (b'shinuist or tiltul min tzad), or have a non-Jew remove it.
Scenario C: Closing the Screen Door on a Summer Afternoon
Your kitchen is full of flies, and you want to close the screen door to prevent more from entering, knowing that the flies currently inside will be trapped.
- According to the Arukh HaShulchan: You may close the screen door without hesitation. The kitchen is a large space where the flies are not confined to a single grasp, and your intention is to protect your home, not to trap the flies. This is a classic permitted case of pesh reishei d'lo nicha lei in a large space.
Chevruta Mini
Now it is your turn to step into the study hall. Discuss the following two questions with your partner, focusing on the trade-offs and conceptual boundaries we have uncovered:
- The Subjectivity of Pain: The Arukh HaShulchan permits trapping painful pests to prevent tza'ar (suffering). In our modern world, where we have insect repellent, air conditioning, and pest control, does our threshold for what constitutes "suffering" change? If someone is extremely phobic of harmless houseflies, does their psychological distress upgrade a harmless fly to the status of a "painful pest," allowing them to trap it on Shabbat? What are the dangers of making halakhic categories subjective to individual psychology?
- The Boundaries of the Home: According to the Arukh HaShulchan, closing a door to a room containing insects is permitted because a room is too large to be considered a "trap." But where do we draw the line? What if you close a small pantry closet? What if you close a small cabinet? At what point does a domestic space shrink from being a "living space" (where closing doors is permitted) to a "trap" (where closing doors is forbidden)? How does this distinction reflect our relationship with our homes on Shabbat?
Takeaway
On Shabbat, we do not surrender our safety or dignity to the wild; rather, we use precise legal boundaries to disarm the threats of nature without asserting ownership over them.
