Arukh HaShulchan, Orach Chaim 315:16-316:4
Sugya Map
The transition from the laws of Ohel (tents and temporary partitions) in Arukh HaShulchan, Orach Chaim 315:16 to the laws of Tzeidah (trapping) in Arukh HaShulchan, Orach Chaim 316:1|316:1-4 represents a conceptual shift from the spatial boundaries of the home to the mastery of man over the animal kingdom. Both sugyot, however, fundamentally negotiate the boundaries of human intervention on Shabbat: when does an act of partition-making constitute the forbidden generation of a new space (Ohel), and when does the containment of a living creature constitute the forbidden subjugation of a free agent (Tzeidah)?
- Primary Issue (Ohel - 315:16): The status of temporary curtains (vilonot) and partitions (mechitzot). Does a hanging fabric that partition a room violate the Rabbinic or Biblical prohibition of Ohel, and does this depend on its functional purpose (modesty versus halachic utility)?
- Primary Issue (Tzeidah - 316:1-4): The definition of the av melachah of trapping. What makes an animal "trapped" (tzad), and how does the category of "species normally hunted" (b'mino nitzod) dictate the severity of the prohibition?
- Nafke Mina (Practical Ramifications):
- Closing a room door: If a wild bird or a domestic pet enters a house or room, does shutting the door constitute a Biblical violation (de'oraita), a Rabbinic violation (derabanan), or is it entirely permissible?
- Hanging decorative drapes: Does the installation of a temporary curtain on Shabbat to block sunlight or wind require a specific manner of hanging (e.g., leaving a handbreadth open)?
- Pest control: To what extent can one trap or contain harmful or annoying insects (such as bees, wasps, or flies) on Shabbat?
- Primary Sources: Shabbat 43b (trapping on Shabbat), Shabbat 106b (trapping a deer in a house), Shabbat 121a (killing and trapping harmful pests), Shabbat 138a (the nature of temporary tents), and Eruvin 102a (the status of curtains).

Text Snapshot
To appreciate the linguistic and conceptual precision of the Arukh HaShulchan, we must examine his specific formulations.
In Orach Chaim 315:16, he writes:
"וילון התלוי לפני הפתח... מותר לנטותו ולהסירו, שאינו עשוי אלא לצניעות ואינו אלא כסות בעלמא..." "A curtain hung before an opening... it is permitted to spread it or remove it, because it is only made for modesty and is nothing more than a mere garment..."[^1]
Here, the Arukh HaShulchan employs the term "kesut b'alma" (a mere garment) to define the ontological status of a curtain. This linguistic choice is crucial: it strips the fabric of its structural identity. It is not an instrument of binyan (building) or Ohel (tents); it is a dynamic, moveable barrier that shares the legal properties of clothing.
In Orach Chaim 316:1, shifting to Tzeidah, he notes:
"כל דבר שהוא במינו ניצוד, פירוש שדרך בני אדם לצודן לעורן או לבשרן או לכל דבר אחר... הצדן בשבת חייב מן התורה." "Any creature whose species is normally hunted—meaning that it is the way of people to hunt them for their skin, their meat, or for any other purpose... one who traps them on Shabbat is liable under Biblical law."[^2]
Note his inclusion of the phrase "o l'chol davar acher" (or for any other purpose). This is a precise expansion of the classic Talmudic definition, indicating that the utility of the animal is not restricted to traditional food or leather, but extends to any systematic human benefit.
In Orach Chaim 316:3, he defines the physical state of being trapped:
"ואימתי הוי צידה? כשיביאנו לידי מקום שאינו מחוסר צידה, דהיינו שאינו צריך לרוץ אחריו..." "And when does it constitute trapping? When one brings it to a place where it is not 'lacking trapping'—that is, where one does not need to run after it..."[^3]
The phrase "eino mechusar tzeidah" (not lacking trapping) is the operational touchstone of the entire sugya. If the animal is confined to a space where it can be seized in a single motion (shechiyah achat), the trapping is complete. If it still requires pursuit, the act of trapping remains incomplete, radically altering the halachic liability.

Readings
The Arukh HaShulchan’s analysis of these sugyot reveals his unique methodology: balancing formalistic legal definitions with a realistic understanding of human activity and domestic life. To fully grasp his contributions, we must contrast his views with those of the major Rishonim and Acharonim.
Reading A: The Spatial Metamorphosis of Ohel (315:16)
The core debate regarding temporary partitions (mechitzot) and curtains (vilonot) on Shabbat rests on whether the act of partitioning creates a "tent" (Ohel) or a "structure" (Boneh).
Is the Partition Permitted on Shabbat?

Biblical Rabbinic Permitted
Violation Violation (Arukh HaShulchan,
(Rishonim) (Rishonim) "Kesut B'alma")
The Gemara in Eruvin 102a distinguishes between a partition made for modesty (tzniut) and one made to permit an activity (such as a mechitzah to permit carrying in an alleyway or a partition to validate a Sukkah).
The Rambam's View
The Rambam in Rambam, Mishneh Torah, Shabbat 22:23 rules that any temporary partition that is not made to permit an activity is permitted to be set up on Shabbat. However, if it permits an activity, it is Rabbinically forbidden as a "temporary tent" (Ohel Aray). The Ravad disagrees, arguing that even a partition for modesty is forbidden if it is fixed firmly.
The Mishnah Berurah's Stringency
The Mishnah Berurah in Mishnah Berurah 315:31|315:31-33 adopts a highly cautious approach, ruling in accordance with the Magen Avraham that even a curtain meant for modesty must not be hung if it is completely fixed to the wall on all sides, as this resembles permanent building (Boneh). He requires that a temporary curtain be left slightly open (at least a handbreadth) or hung in a loose manner that demonstrates its impermanence.
The Arukh HaShulchan's Chiddush
Rabbi Yechiel Michel Epstein (the Arukh HaShulchan) charts a remarkably lenient and conceptually elegant path. He argues that a standard door-curtain (vilon) or window-blind is never subject to the laws of Ohel or Boneh. Why? Because its very design and essence is to be constantly opened and closed (asuy l'histalek).
By defining the curtain as "kesut b'alma" (a mere garment), he shifts the focus from the physical act of hanging to the functional identity of the object. A garment does not become a wall merely because it hangs vertically. Since the curtain does not create a permanent division of space and is meant to be moved constantly, it lacks the cheftza (halachic object-status) of a partition.
Therefore, the Arukh HaShulchan rules that one may hang or remove any standard curtain on Shabbat without requiring any special modifications or leaving a handbreadth open, provided it is not being hung to validate an Eruv or a Sukkah.
Reading B: The Ontological Definition of "B'mino Nitzod" (316:1-2)
The definition of trapping hinges on the biological and sociological classification of the animal being trapped. The Torah only prohibits the trapping of a species that is "normally hunted" (b'mino nitzod). If a species is not normally hunted (ein b'mino nitzod), trapping it is only a Rabbinic prohibition.
The Debate between Rashi and Rambam
What makes an animal b'mino nitzod?
- Rashi's Definition: In his commentary on Shabbat 106b, Rashi explains that b'mino nitzod refers to species that are hunted for their commercial value—specifically, those hunted for their skins or their meat (such as deer, foxes, and fish). If a species has no commercial utility, it is not b'mino nitzod.
- Rambam's Definition: In Rambam, Mishneh Torah, Shabbat 10:1-2, the Rambam presents a different formulation. He focuses on the utility of the act rather than the general commercial classification of the species. If an individual traps an animal for a specific purpose (even if the species is not generally hunted by the public), he may be liable. Conversely, the Rambam holds that trapping an animal "not for its body" (shelo l'tzorech gufo—meaning one traps it merely to avoid being bitten or to remove it from the house) is exempt from Biblical liability (patur aval asur) because it is a melachah she'eina tzerichah l'gufah (a labor not needed for its own sake).
The Arukh HaShulchan's Synthesis
The Arukh HaShulchan Arukh HaShulchan, Orach Chaim 316:1|316:1-2 synthesizes these views with a brilliant sociological insight. He defines b'mino nitzod as a dynamic, context-dependent category.
The question is not merely taxonomic, but functional: Does society at large view this creature as a harvestable resource? If a community hunts a specific animal for any constructive purpose—whether for food, clothing, scientific research, or domestication—it falls under b'mino nitzod.
However, if a creature is trapped solely to prevent it from causing annoyance or minor damage (such as flies or common beetles), it is inherently ein b'mino nitzod. The Arukh HaShulchan notes that because these pests are not hunted for any benefit, their trapping can never rise to the level of a Biblical violation.
By grounding the definition of b'mino nitzod in societal utility, he establishes a clear, objective framework that accounts for historical and geographical variations in hunting practices.
Reading C: The Spatial Mechanics of "Mechusar Tzeidah" (316:3-4)
Once the classification of the animal is established, we must analyze the physical act of containment. Under what spatial conditions is an animal considered "trapped"?
The Gemara in Shabbat 106b presents a classic case:
"תנו רבנן: הצד צבי... נעל בפניו - חייב." "Our Rabbis taught: One who traps a deer... if he locks the door in front of it, he is liable."
However, the Gemara immediately qualifies this: if the deer enters a large house and one locks the door, the trapper is exempt, because the deer is still "lacking trapping" (mechusar tzeidah). In a large house, one must still chase the deer to catch it. If it enters a small cubicle (bayit katan), locking the door is a Biblical violation because the deer can be grabbed in a single movement.

The Ran's Formulation
The Ran on Shabbat (37b in the Rif's pages) explains that the definition of a "small space" is relative to the agility and nature of the animal. A slow, lumbering animal is considered trapped even in a larger room, whereas a swift bird or a highly agile insect is only considered trapped in a very small container (like a cage or a jar).
The Arukh HaShulchan's Precision
In Arukh HaShulchan, Orach Chaim 316:3, the Arukh HaShulchan codifies this relative spatial theory with extreme precision:
"ושיעור מקום קטן הוא: כל שאם ירצה לאחוז בו, יאחזנו מיד בשחייה אחת... ואם הוא מקום גדול שצריך לרוץ אחריו... אין זו צידה גמורה מן התורה." "And the measure of a small space is: any space where, if one wishes to seize the animal, he can seize it immediately in a single lunge... But if it is a large space where one must run after it... this is not complete trapping under Biblical law."[^4]
The Arukh HaShulchan applies this principle to domestic spaces. If a wild bird flies into a modern house, closing the front door does not constitute a Biblical violation of Tzeidah, because the bird can still fly freely within the high ceilings and multiple rooms of the house. The bird remains mechusar tzeidah.
Closing the door is only a Rabbinic prohibition (sh'vut). This distinction is not merely academic; as we will see, it serves as the foundation for his lenient rulings regarding pest control and accidental trapping.
[^4]: Arukh HaShulchan, Orach Chaim 316:3
Friction
The sugya of Tzeidah is rife with internal conceptual tensions. The most prominent friction lies at the intersection of pest control, Rabbinic prohibitions, and the prevention of pain or discomfort (tza'ar).
The Kushya: The Paradox of Trapping Harmful Pests
The Mishnah in Shabbat 121a states:
"כל החיה והרמש הנושכים... מותר להרגן בשבת." "All wild beasts and creeping things that bite... one may kill them on Shabbat."
If one is permitted to kill a dangerous animal (which violates the av melachah of Netilat Neshamah / killing), it should logically follow that one is permitted to trap them (which is a lesser or equal violation). Yet, the Shulchan Aruch in Shulchan Aruch, Orach Chaim 316:10 rules that one may not trap harmful insects or pests unless they are actively pursuing a person to bite them. If they are merely sitting in the room, one may only cover them with a cup or vessel to prevent them from causing harm, but one may not trap them in a permanent way.
This presents a profound conceptual difficulty:
- If the insect is dangerous, why can we only cover it with a cup rather than trapping it directly or killing it?
- If the insect is not dangerous but merely a nuisance (like a fly or a mosquito), trapping it is a Rabbinic prohibition (ein b'mino nitzod). If so, why is covering it with a cup permitted? Covering it with a cup is an act of trapping! By placing a cup over a fly on a table, you have instantly trapped it in a "small space" where it is no longer mechusar tzeidah. This is a direct Rabbinic violation of Tzeidah! How can Chazal permit a direct Rabbinic violation merely to avoid the minor annoyance of a fly?
The Terutz: The Arukh HaShulchan's Resolution
The Arukh HaShulchan Arukh HaShulchan, Orach Chaim 316:4 resolves this friction by introducing a multi-tiered conceptual matrix that balances the severity of the melachah, the intention of the actor, and the degree of human suffering (tza'ar).

(De'oraita Cover (Cup) Permitted

Step 1: The Nature of the Threat
The Arukh HaShulchan distinguishes between three categories of creatures:
- Mortal Danger (Pikuach Nefesh): A rabid dog, a venomous snake, or a deadly scorpion. These may be killed or trapped directly and without limitation, as saving a life overrides all Shabbat laws.
- Pain-Inflicting (Maziik): Creatures that cause significant pain but are not deadly, such as wasps, hornets, or biting spiders.
- Mere Nuisance (Tza'ar B'alma): Common flies, mosquitoes, or fleas that cause minor discomfort or itchiness but do not inflict severe pain.
Step 2: Unpacking the "Cup Cover" Permissibility
How can we cover a pain-inflicting pest (Category 2) or even a mere nuisance (Category 3) with a cup if doing so constitutes Rabbinic trapping?
The Arukh HaShulchan explains that placing a cup over an insect is a unique form of trapping. It is a sh'vut d'sh'vut b'makom tza'ar—a double Rabbinic prohibition in a case of human suffering or need, which Chazal permitted.
Let us isolate the two Rabbinic layers:
- Layer 1 (The Animal): The insect is ein b'mino nitzod (not a species normally hunted). Trapping it is therefore only a Rabbinic prohibition.
- Layer 2 (The Intent): The person trapping the insect has absolutely no interest in the insect itself. He does not want its body, its meat, or its skin. This is a melachah she'eina tzerichah l'gufah (labor not needed for its own sake), which according to Rabbi Shimon (whose opinion we rule by) is only a Rabbinic prohibition.
When these two Rabbinic leniencies combine (ein b'mino nitzod + she'eina tzerichah l'gufah), the act of trapping becomes a distant, weak Rabbinic prohibition.
Step 3: The Principle of "Lo Gazru" (Chazal Did Not Decree)
The Arukh HaShulchan invokes a fundamental meta-halachic principle:
"שלא גזרו חכמים במקום צער." "For the Sages did not apply their decrees in a place of pain."[^5]
Chazal did not design the Rabbinic laws of Shabbat to render a person helpless in the face of physical suffering. If an insect is causing pain (Category 2), one may trap it directly with a cup.
What if it is a mere nuisance (Category 3), like a fly? Here, the Arukh HaShulchan argues that one may not trap it directly with a cup, because the level of tza'ar (discomfort) does not warrant suspending even a double Rabbinic prohibition. However, one may close a door or window to prevent more flies from entering, or to trap them in a larger room, because closing a door on flies in a large room is not complete trapping (they remain mechusar tzeidah in the room).
Thus, the Arukh HaShulchan elegantly aligns the physical reality of the insect's agility, the spatial dimensions of the room, and the psychological reality of human pain to create a seamless, highly practical halachic framework.

Intertext
To fully appreciate the Arukh HaShulchan’s mastery, we must examine how his rulings in 315:16 and 316:1-4 interface with biblical antecedents, classical codes, and later responsa.
The Biblical Anchor: The Mishkan as the Blueprint for Tzeidah
Every av melachah of Shabbat must be derived from the activities performed during the construction of the Mishkan (Tabernacle) in the wilderness, as taught in Shabbat 49b.
Mishkan Blueprint for Trapping
│
Why trap in the Mishkan?
│
To obtain animal skins
(Tachash and Elim Me'odamim)
│
Must be "M'lechet Machashevet"
(Constructive, purposeful hunting)
The Torah in Exodus 26:14 commands the creation of covers for the Mishkan made of "red-dyed rams' skins and tachash skins." To obtain these skins, the builders of the Mishkan had to hunt and trap these animals.
This biblical origin establishes the essential character of Tzeidah:
- It must be an act of m'lechet machashevet (purposeful, creative labor). The hunting in the Mishkan was highly professional, systematic, and aimed at harvesting a valuable resource (skins).
- This supports the Arukh HaShulchan’s insistence that Tzeidah is fundamentally defined by utility. If one traps an insect merely to get rid of it, this lacks the constructive character of the hunting in the Mishkan. It is a melachah she'eina tzerichah l'gufah (labor not needed for its own sake), which is why it is downgraded to a Rabbinic prohibition.
The Shulchan Aruch and Mishnah Berurah Parallel
In Shulchan Aruch, Orach Chaim 316:1, the Mechaber (Rabbi Yosef Karo) writes:
"הצד חיה ועוף... חייב." "One who traps a beast or a bird... is liable."
The Mishnah Berurah (316:4) comments that if a domestic pet (such as a dog or cat) escapes the house, it is Rabbinically forbidden to trap it unless it is resisting capture and requires significant effort to catch.
The Arukh HaShulchan Arukh HaShulchan, Orach Chaim 316:2 takes a more nuanced approach. He argues that domestic animals that are fully accustomed to human presence and naturally return to their homes at night are considered nitzod v'omed (already trapped).
Status of Domestic Pets

│ Biblical/Rabbinic

Contain/Grab
Because they have no desire to flee and are entirely subject to their owner's will, the transition from "freedom" to "captivity" cannot occur. Therefore, grabbing a domestic dog by its collar or closing a door to keep it in a room is completely permitted on Shabbat and does not violate even a Rabbinic prohibition. This represents a significant practical leniency over the Mishnah Berurah.
Responsa Literature: The Chasam Sofer on Pest Control
The principles discussed by the Arukh HaShulchan are echoed and expanded in the Responsa of the Chasam Sofer (Orach Chaim, Responsum 83). The Chasam Sofer was asked whether a scientist or doctor is permitted to trap insects on Shabbat for medical research or to prevent the spread of disease.
The Chasam Sofer utilizes the same conceptual machinery as the Arukh HaShulchan:
- If the insects are being trapped for medical research, the act is now tzerichah l'gufah (needed for its own sake), because the trapper actually wants the physical body of the insect for study. This elevates the act to a potential Biblical violation if the insect is b'mino nitzod.
- However, since most common insects are ein b'mino nitzod, the prohibition remains Rabbinic.
- In a case of public health necessity (preventing disease), the Rabbinic prohibition is suspended under the rubric of tza'ar rabim (public suffering) or she'at ha-dechak (pressing need).
This aligns perfectly with the Arukh HaShulchan’s view that the halachic status of trapping is dynamic, constantly negotiating the space between human utility, animal biology, and physical necessity.
Psak/Practice
How do the conceptual innovations of the Arukh HaShulchan manifest in modern, practical halachic decision-making?
Case 1: The Screen Door and the Fly
A common scenario on a hot summer Shabbat: a fly or mosquito enters a home. The homeowner wants to close the screen door to prevent more bugs from entering, but doing so will trap the fly inside the house.
- According to the Arukh HaShulchan: Closing the screen door is completely permitted.
- Reasoning: The house is a large space, meaning the fly is still mechusar tzeidah (lacking trapping) because it can fly freely throughout the rooms and cannot be caught in a single grab. Furthermore, the homeowner’s intent is to keep other bugs out (a constructive purpose), not to trap the fly inside (lo nicha lei—unwanted consequence). This is a psik reisha d'lo nicha lei (an inevitable but undesired consequence) on a Rabbinic prohibition (Tzeidah of an insect in a large room), which the Arukh HaShulchan permits.
Case 2: The Escaped Pet Bird
A pet parrot escapes its cage and is flying around a small bedroom. Can the owner close the bedroom door to prevent it from escaping into the rest of the house?
- According to the Arukh HaShulchan: Closing the bedroom door is permitted, but catching the bird with one's hands or a net is forbidden.
- Reasoning: Closing the bedroom door confines the bird to a smaller space, but because the room is still large enough that the bird can fly out of reach, it remains mechusar tzeidah. Thus, closing the door is only a Rabbinic restriction. Since the owner is doing this to prevent the loss of his property (hefsed), and the bird is domesticated (nitzod v'omed in a general sense), closing the door is permitted. However, actually grabbing the bird or throwing a blanket over it would confine it to a state of complete trapping (eino mechusar tzeidah), which is forbidden.
Case 3: The Wasp in the Dining Room
A wasp is buzzing around the Shabbat dining table, causing panic among the family members.
- According to the Arukh HaShulchan: One may place a plastic cup or bowl over the wasp to trap it on the table.
- Reasoning: Although placing a cup over the wasp instantly traps it (a Rabbinic violation of Tzeidah), the wasp is a maziik (a creature that inflicts painful stings). Because of the threat of pain (tza'ar), Chazal did not apply their Rabbinic decrees (lo gazru), allowing one to contain the threat.

Takeaway
The Arukh HaShulchan conceptualizes the Shabbat laws not as a series of arbitrary, clinical restrictions, but as a dynamic framework where physical reality and human needs are deeply integrated. Trapping (Tzeidah) is redefined from a mechanical act of confinement to a functional transition of utility; when an act of trapping lacks constructive purpose or occurs within a space that still requires pursuit, Chazal suspend their restrictions to preserve human dignity, comfort, and peace of mind.
