Arukh HaShulchan, Orach Chaim 317:11-18
Hook
At first glance, tying a knot seems like a purely physical act of joining two cords. Yet, in the eyes of Shabbat law, a knot is not defined by its physical tightness, but by its relationship with time and human intention. In this exploration of the Arukh HaShulchan, we will discover how a simple double-knot on a shoe can transform from a mundane action into a profound philosophical clash between objective physical structure and subjective human consciousness.

Context
To understand the genius of Rabbi Yechiel Michel Epstein (1829–1908), the author of the Arukh HaShulchan, we must place him in his historical and literary landscape. Writing in Novardok, Belarus, during the late nineteenth and early twentieth centuries, Rav Epstein lived in an era of massive transition. It was a time when the traditional Jewish world was facing the challenges of modernity, industrialization, and internal ideological shifts. In the realm of Halakha (Jewish law), his contemporary, Rabbi Yisrael Meir Kagan (the Chofetz Chaim), was compiling the Mishnah Berurah.
While the Mishnah Berurah functions as an encyclopedic, highly cautious digest of preceding authorities—often leaning toward stringency to accommodate all opinions—the Arukh HaShulchan takes a fundamentally different, highly dynamic approach. Rav Epstein does not merely collect opinions; he seeks the underlying conceptual harmony of the law. He traces each halakhic ruling from its Talmudic source down through the medieval commentators (Rishonim) to the later legal codes (Acharonim), demonstrating how the law evolves naturally and logically.
Rav Epstein possesses an extraordinary confidence in the integrity of Jewish practice. His methodology is deeply rooted in the belief that the lived reality of the Jewish people (puk chazi mai ama davar—"go out and see what the people are doing") is a vital component of halakhic truth.
When we study his analysis of Koshair (tying) and Matir (untying)—one of the thirty-nine forbidden creative activities (Avot Melachot) on Shabbat, as derived from the construction of the Tabernacle in Mishnah Shabbat 7:2—we are not just studying a list of do's and don'ts. We are witnessing a master jurist reconcile a centuries-old debate regarding what constitutes a "permanent knot" (kesher shel kayama).
In the Tabernacle (Mishkan), knots were tied and untied in the process of weaving curtains and repairing the nets used to catch the chilazon (the snail from which the blue techelet dye was extracted), as discussed in Talmud Shabbat 74b. From these ancient, wilderness-era crafts, Rav Epstein extracts a sophisticated legal theory of temporal permanence, structural integrity, and human agency that speaks directly to the intermediate learner seeking to transition from rote observance to conceptual fluency.
Text Snapshot
The following is a curated snapshot of the core conceptual moves made by the Arukh HaShulchan in Orach Chaim 317:11-18. You can study the full text on Sefaria at Arukh HaShulchan, Orach Chaim 317:11-18.
ערוך השולחן אורח חיים שקי״ז:י״א כלל הדבר בקשר: דקשר של קיימא ומעשה אומן – אסור מן התורה, וכן קשר שאינו של קיימא ומעשה אומן, או קשר של קיימא ואינו מעשה אומן – אסור מדרבנן. ואיזהו קשר של קיימא? כל שעשוי לעמוד לעולם, או לזמן מרובה...
Arukh HaShulchan, Orach Chaim 317:11 "The general rule concerning knots is: a permanent knot (kesher shel kayama) that is also the work of a craftsman (ma'aseh uman) is forbidden by Biblical law (De'oraita). Likewise, a knot that is not permanent but is the work of a craftsman, or a permanent knot that is not the work of a craftsman, is forbidden by Rabbinic law (Derabanan). And what is considered a permanent knot? Any knot that is made to stand forever, or for a long period of time..."
ערוך השולחן אורח חיים שקי״ז:ט״ו ועניבה מותר לכתחילה, שאינו קשר כלל... אלא שזהו דווקא בעניבה לבד, אבל לעשות קשר ואחר כך עניבה על הקשר – יש בזה מבוכה גדולה בין הרבוותא...
Arukh HaShulchan, Orach Chaim 317:15 "And a bowknot (aniva) is permitted from the outset, as it is not considered a knot at all... However, this is specifically regarding a bowknot alone; but to make a knot and then a bowknot on top of that knot—there is great confusion among the great authorities regarding this..."
Close Reading
To truly appreciate the depth of the Arukh HaShulchan, we must execute a rigorous close reading of paragraphs 11 through 18. Rav Epstein does not merely state laws; he constructs a dialectical architecture. Let us break this down into three distinct areas of analysis: the structural progression of his argument, the linguistic nuances of his key terms, and the profound legal-philosophical tensions he seeks to resolve.
Structure: The Dialectical Descent
Rav Epstein’s presentation in these paragraphs is structured as a descending staircase, moving from abstract, high-level principles to increasingly granular, everyday applications.
He begins in Paragraph 11 by establishing the constitutional grid of the Melacha. He maps out the two primary axes of liability: the physical/professional nature of the knot (craftsman vs. amateur) and the temporal duration of the knot (permanent vs. temporary). This four-quadrant grid is essential for any intermediate student to memorize, as it governs the entire landscape of Shabbat laws:
- Craftsman + Permanent: Forbidden De'oraita (Biblically).
- Craftsman + Temporary: Forbidden Derabanan (Rabbinically).
- Amateur + Permanent: Forbidden Derabanan (Rabbinically).
- Amateur + Temporary: Permitted L'chatchilah (Ab initio).
Once this theoretical taxonomy is established, the structure of the next several paragraphs serves to define the boundaries of these categories.
In Paragraph 12, he zeroes in on the most volatile variable in this equation: time. What does "permanent" (shel kayama) actually mean? Is it a subjective measure of human intent, or is there an objective threshold of days, weeks, or months? He reviews the opinions of the major medieval codifiers, highlighting how they struggle to define a clear boundary.
In Paragraphs 13 and 14, he transitions from time to physical form. He examines the anatomy of the knot itself. What happens when we tie a single knot? What happens when we stack knots? Here, the structure of his thought moves from the abstract concept of "tying" to the mechanics of friction, rope, and leather. He analyzes the "double knot" (kesher koful), which is the most common knot used by laypeople today.
In Paragraphs 15 and 16, the Arukh HaShulchan addresses the hybrid forms—specifically, the bowknot (aniva). He raises a classic structural question: is a bowknot a weak knot, or is it conceptually not a knot at all? By dissecting the bowknot, he prepares the reader for the ultimate synthesis of intent and action.
Finally, in Paragraphs 17 and 18, he applies this entire theoretical apparatus to practical, lived experience. He discusses the knots of animal-herders, boat-captains, and, ultimately, the shoes on our feet. This structural descent—from the lofty heights of Biblical and Rabbinic definitions down to the laces on a leather boot—is the hallmark of Rav Epstein’s pragmatic genius. He does not leave the law in the heavens; he anchors it firmly in the dust of daily human existence.

Key Term: "Kesher Shel Kayama" and "Ma'aseh Uman"
To achieve fluency in this area of Halakha, we must unpack the precise vocabulary utilized by the Arukh HaShulchan. The two most critical terms are Kesher Shel Kayama (a permanent knot) and Ma'aseh Uman (the work of a craftsman).
Let us first analyze "Ma'aseh Uman." In the classical Talmudic context of Talmud Shabbat 111b, the ultimate paradigms of professional knots are the kesher hagamalin (the knot of camel-drivers) and the kesher hasapanim (the knot of sailors). Why these two?
A camel-driver's knot is tied to a metal ring on the camel's nose-harness. It must withstand the immense, jerking physical force of a pack animal. If the knot slips, the camel escapes, and the merchant's entire livelihood is lost.
Similarly, a sailor's knot secures a vessel to a dock or holds sails under the high-tension force of ocean winds. These are not simple overhand knots; they require specialized, professional knowledge to tie and untie. They are designed to hold fast under extreme load, yet be capable of being undone by someone who knows the craft.
Rav Epstein emphasizes that Ma'aseh Uman is defined by this professional, highly skilled nature. If a knot requires unique training or a specific technique that ordinary people do not possess, it falls into this category. Conversely, a kesher hedyot (an amateur knot) is one that any child or untrained layperson can tie.
Now, let us examine "Kesher Shel Kayama." Literally, this translates as a "knot of standing" or a "durable knot." The term kayama shares a root with kayam (existence, permanence). But how do we measure "permanence" in a world where nothing lasts forever?
Does it mean the knot is intended to stay tied for the rest of human history? Or does it mean it is meant to stay tied for a year, a month, or a week?
As Rav Epstein notes in Paragraph 12, there is a massive conceptual divide here. Some Rishonim, such as the Rambam, appear to define "permanent" as a knot that is tied with no intention of ever untying it. If you tie a knot with the plan to eventually undo it—even if that eventuality is months away—it may not qualify as a true kesher shel kayama on a Biblical level.
However, other authorities, most notably the Rosh, introduce a much tighter temporal boundary. They argue that if a knot is meant to remain tied for a significant duration (such as seven days), it is rabbinically treated as "permanent."
The Arukh HaShulchan carefully parses these terms, showing that "permanence" is not a purely physical attribute of the rope; it is a compound concept made of physical durability and human intent.
Tension: Objective Form vs. Subjective Intent
The core intellectual tension that vibrates through these paragraphs of the Arukh HaShulchan is the clash between objective physical form and subjective human intent.
Consider this scenario: A person takes a piece of string and ties a tight, complex double-knot. Physically, this knot is highly durable; it could easily remain intact for years. However, the person who tied it has a clear, subjective intention to untie it in exactly two hours.
How does Halakha view this act? Do we look at the physical reality of the knot (which is objectively permanent and durable), or do we look at the mind of the actor (who subjectively intends for it to be temporary)?
In Paragraph 16, Rav Epstein wrestles with this precise cognitive dissonance. He explores the concept of da'at (human intention). If a person ties an amateur knot with the explicit intention of leaving it tied forever, that subjective intent elevates the knot to the status of kesher shel kayama, making it rabbinically forbidden to tie on Shabbat.
But what about the reverse? If you tie a knot that is physically designed to be permanent, can your subjective intention to untie it later save you from a violation?
The Arukh HaShulchan reveals that subjective intent has its limits. If you perform an act that is objectively defined as a professional, permanent-style knot, your silent mental reservation ("I plan to untie this later") cannot strip the physical action of its objective halakhic character.
This tension is beautifully illustrated in his discussion of the bowknot (aniva) in Paragraph 15. Physically, a bowknot is designed to be undone easily by simply pulling one of the loose ends. It lacks structural friction. Because of this objective physical form, the Sages declared that a bowknot is not considered a knot at all (aino kesher klal). Even if you have the subjective intent to leave a bowknot tied on your shoe for the next ten years, the physical form of the bow remains objectively temporary.
This creates a fascinating, asymmetric legal landscape:
- Subjective intent can upgrade a physically temporary amateur knot into a forbidden permanent knot.
- However, subjective intent cannot downgrade an objectively permanent, professional knot into a permitted temporary one, nor can it transform a non-knot (like a bow) into a formal halakhic knot.
By tracing this tension, Rav Epstein teaches us a profound lesson about the nature of Shabbat: our mental states and our physical actions are in a constant, dynamic dialogue. The holiness of the day is constructed at the precise intersection of human consciousness and physical reality.
Two Angles
To truly master this passage of the Arukh HaShulchan, we must examine how he navigates the historic debate between the two towering titans of medieval Jewish law: Rambam (Maimonides) and the Rosh (Rabbeinu Asher), who builds upon the foundational interpretations of Rashi. This debate centers on the exact relationship between the physical nature of the knot and its temporal duration.
[RAMBAM'S AXIS] [RASHI / ROSH AXIS]
Focus: Physical Craftmanship Focus: Temporal Duration (Time)
(Is it a professional knot?) (How long will it remain tied?)
│ │
├──► Professional = Biblical ├──► Under 24 Hours = Permitted
└──► Amateur = Rabbinic/Permitted └──► Over 7 Days = Forbidden
Angle 1: Rambam’s Structural-Craftsmanship Model
The Rambam, in his Mishneh Torah (Hilkhot Shabbat 10:1-2), presents a highly objective, structural model of Koshair. For Maimonides, the primary factor that determines whether a knot is biblically prohibited is craftsmanship (ma'aseh uman).
According to the Rambam:
- If a knot is a professional knot (like a sailor's or camel-driver's knot) and it is intended to be permanent, it is a Biblical violation (De'oraita).
- If a knot is a professional knot but intended to be temporary, or if it is an amateur knot but intended to be permanent, it is a Rabbinic violation (Derabanan).
- If it is an amateur knot and intended to be temporary, it is entirely permitted (L'chatchilah).
For the Rambam, the definition of "permanent" is absolute: it must be meant to remain tied indefinitely, with no plan to ever untie it. If there is any plan to untie it in the future, it is not "permanent" on a Biblical level.
The Rambam's focus is on the nature of the act itself. Is the person engaging in the skilled craft of a weaver or a sailor? If the physical knot does not require professional skill, the Biblical prohibition of Koshair is simply not triggered, regardless of how long the knot remains tied.
Angle 2: Rashi and Rosh’s Temporal-Duration Model
In sharp contrast, Rashi (in his commentary on Talmud Shabbat 111b) and the Rosh (in his halakhic compendium) champion a temporal-duration model. They argue that the primary, defining characteristic of a "permanent knot" is not the professional skill required to tie it, but how long it is meant to stay tied.
The Rosh establishes a clear, practical timeline:
- If a knot is tied with the intention of being untied within twenty-four hours, it is considered completely temporary and is permitted to be tied, provided it is not a professional knot.
- If a knot is tied with the intention of remaining intact for more than seven days, it is considered "permanent" (shel kayama), and tying it constitutes a severe rabbinic or even biblical violation, depending on the professional nature of the knot.
- Any period between twenty-four hours and seven days falls into a gray zone of rabbinic doubt and stringency.
For the Rosh, the physical structure of the knot is secondary to its temporal reality. If you tie a simple, amateur double-knot on a sack of flour, but you intend to leave that knot tied for a month, that knot has effectively become a permanent fixture of the world. By leaving it tied, you have engaged in a creative act of binding that alters the state of physical objects over time.
The Arukh HaShulchan’s Synthesis
Rav Epstein masterfully navigates this clash of titans. He points out that the Shulchan Aruch (Shulchan Aruch, Orach Chaim 317:1) attempts to weave these two models together, creating a highly stringent matrix that incorporates the strictures of both the Rambam and the Rosh.
However, Rav Epstein pushes back against excessive stringency that would paralyze daily life. He analyzes the physical mechanics of common knots to show that many of our daily actions do not violate either model.
For example, he argues that our modern shoelaces are designed by their very nature to be tied and untied daily. Therefore, even if we tie a double knot on our shoes, it cannot be classified as "permanent" under either the Rambam's model (as there is clear intent to untie it within a day) or the Rosh's model (as it does not cross the seven-day threshold).
By contrasting these two angles, the Arukh HaShulchan allows the intermediate student to see that Halakha is not a monolithic wall of restrictions, but a sophisticated debate between structural and temporal definitions of reality.
Practice Implication
How does this complex theoretical framework translate into our daily Shabbat observance? The laws of Koshair and Matir are among the most frequently encountered Melachot in a modern home. Let us examine three common real-world scenarios through the lens of the Arukh HaShulchan's rulings.
┌──────────────────┬─────────────────────────────┬───────────────────────────┐

└──────────────────┴─────────────────────────────┴───────────────────────────┘
Scenario 1: Tying Trash Bags and Food Bags
Imagine you are cleaning up after the Friday night Shabbat meal. The trash can is full, and you want to tie up the plastic garbage bag. The bag has two plastic flaps. Naturally, you want to tie them together to prevent trash from spilling out.
If you tie a classic double-knot (tying the flaps once, and then tying them again on top of the first knot), you have just created a highly secure, tight knot. Crucially, you have no intention of ever untying this knot; the bag is going directly into the dumpster.
According to the Arukh HaShulchan’s analysis:
- This is an amateur knot (kesher hedyot).
- However, it is intended to remain tied forever (shel kayama).
- Therefore, tying it falls under the Rabbinic prohibition of Koshair.
The Practical Solution: How do you close the bag without violating Shabbat?
- You can tie a single overhand knot. A single knot, without a second knot on top to lock it in place, is structurally unstable and does not halakhically constitute a "knot" in this context.
- You can tie a bowknot (aniva). Since a bowknot is structurally designed to slip open easily, it is completely permitted to tie on Shabbat, even if the bag is going to be thrown away.
- You can use the plastic loop-handles of the bag to slip one through the other without creating a locking knot.
Scenario 2: Double-Knotting Children's Shoes
Your toddler's shoes keep coming untied on Shabbat afternoon. To prevent them from tripping, you want to tie their shoelaces in a tight double-knot (a single knot, followed by a bow, and then looping the bow-ends into another knot—the classic "double-knot").
Can you do this on Shabbat?
According to Rav Epstein's analysis in Paragraphs 14 and 15:
- A standard bow over a single knot is completely permitted, as the bow is not a knot.
- However, when you tie a double-knot (locking the bow into a second knot), you are creating a highly secure structure.
- If you plan to leave this double-knot intact for several days (for example, so you don't have to re-tie the toddler's shoes on Sunday and Monday), you have crossed the temporal threshold of the Rosh, creating a forbidden temporary-to-permanent knot.
The Practical Solution: If you must tie a double-knot on Shabbat, you must have the explicit intention to untie it within twenty-four hours (e.g., when you take the shoes off the child on Saturday night). However, to avoid all halakhic doubt, the best practice is to tie a very tight single knot and a standard bow, avoiding the locking double-knot altogether on Shabbat.
Scenario 3: Dealing with Twist-Ties and Toy Packaging
You buy a new toy for your child, or you want to open a loaf of bread that is secured with a plastic-coated metal twist-tie. Is twisting and untwisting a wire considered Koshair or Matir?
Strictly speaking, a metal twist-tie does not hold together by friction and interlocking loops in the way a rope knot does; it holds together because the metal wire is bent and retains its shape.
While some modern halakhic authorities (such as the Minchat Yitzchak) rule that twisting a wire is rabbinically equivalent to tying a knot, others are more lenient.
To stay firmly within the safe boundaries of Halakha on Shabbat:
- When closing a bread bag, instead of twisting the wire tie multiple times, simply fold the neck of the bag over or use a plastic clip.
- When opening a toy that is bound to its cardboard packaging with tight twist-ties, instead of untwisting them (which might violate Matir—untying), it is often preferable to safely cut the plastic-coated wire with scissors, which destroys the "knot" entirely, rendering the act an act of destructive opening rather than systematic untying.
Chevruta Mini
Now it is your turn to step into the Beit Midrash. Grab a study partner, or take a moment to reflect deeply on these two highly analytical questions designed to surface the core trade-offs of the Arukh HaShulchan’s system.
Question 1: The Philosophy of the Twist-Tie
A plastic-coated metal twist-tie holds its shape through the physical bending of metal, not through the friction of interlocking ropes.
- The Challenge: Based on the Arukh HaShulchan's definition of Ma'aseh Uman (craftsmanship) and the physical nature of a knot, does a twist-tie qualify as a halakhic knot?
- The Trade-off: If you argue that it is a knot because it achieves the same functional result (binding), you expand the definition of Koshair to include non-roped materials. If you argue it is not a knot because it lacks the structural form of interlocking cords, you must permit twisting and untwisting metal wires on Shabbat. How would Rav Epstein resolve this balance between functional result and formal physical structure?
Question 2: The Retroactive Intent Dilemma
Imagine you tie an amateur knot on Shabbat morning with the firm, sincere intention of untying it that evening (completely permitted under the 24-hour rule). On Saturday night, you forget to untie it. On Sunday, you forget again. In fact, the knot remains tied for a month.
- The Challenge: Did you retroactively violate Shabbat on Saturday morning?
- The Trade-off: If Halakha looks purely at your initial subjective intent, you did nothing wrong, because at the moment of the action, your mind was aligned with a temporary act. But if Halakha looks at the objective reality of what happened (the knot stood for a month), then your action retroactively became a permanent knot. How does the Arukh HaShulchan navigate this temporal paradox? Refer back to his analysis of da'at (human intention) in Paragraph 16.
Takeaway
On Shabbat, we do not merely refrain from physical labor; we surrender our mastery over time and structure by ensuring that our temporary actions remain beautifully, intentionally transient.
