Arukh HaShulchan, Orach Chaim 317:19-27
Hook
We often think of the laws of Shabbat as rigid, objective physical boundaries where a knot is either a knot or it isn't. But what if the ultimate factor that determines whether you have violated a biblical prohibition on Shabbat is not the physical structure of the knot itself, but the silent, psychological horizon of your own calendar?

Context
To understand the genius of the Arukh HaShulchan, we must step into the world of its author, Rabbi Yechiel Michel Epstein (1829–1908). Serving as the Rabbi and head of the rabbinical court (Av Beit Din) of Novardok, Belarus, for over thirty years, Rabbi Epstein was a towering halakhic authority of the late 19th and early 20th centuries. His monumental work, the Arukh HaShulchan, covers the entirety of the Shulchan Arukh, presenting a fluid, comprehensive, and highly practical guide to Jewish law.
Historically, Rabbi Epstein’s work stands in fascinating dialogue—and occasional tension—with his contemporary, Rabbi Yisrael Meir Kagan (the Chafetz Chaim), author of the Mishnah Berurah. While the Mishnah Berurah was compiled as a digest of opinions designed to guide the reader toward a highly protective, often stringent consensus, the Arukh HaShulchan was written from the active bench of a communal judge. Rabbi Epstein’s halakhic methodology is deeply integrated with the lived reality of his community. He operates from a fundamental, pastoral-legal premise: if the Jewish people have a widespread, intuitive practice, there must be a valid, sophisticated halakhic defense for it (limud zechut).
In the realm of Melachat Kosher (the creative labor of tying) and Matir (untying), this pastoral-legal philosophy is put to its ultimate test. Tying is one of the thirty-nine forbidden creative labors (Melachot) derived from the construction of the Tabernacle, as recorded in Mishnah Shabbat 7:2. In the Tabernacle, knots were tied in the nets used to catch the snails that yielded the blue tekhelet dye, or in the sewing of the curtains. However, unlike heavy agricultural building or industrial weaving, tying is an inescapable, daily domestic necessity. Sages throughout history have struggled to define what makes a knot a "knot" in the eyes of Shabbat law. Is it defined by its physical tightness, its professional craftsmanship, or its intended lifespan?
In Orach Chaim 317:19-27, Rabbi Epstein navigates these intricate, centuries-old debates of Talmudic sages and medieval Rishonim. He constructs a framework that preserves the sanctity of Shabbat without rendering the simple act of putting on one’s shoes or securing a garment an existential legal minefield for the average Jew.
Text Snapshot
Below is a curated selection of key passages from Rabbi Epstein’s discussion in Arukh HaShulchan, Orach Chaim 317:19-27, tracking his core arguments regarding the double knot and the defense of common practice. The full text can be studied on Sefaria at Arukh HaShulchan, Orach Chaim 317:19-27.
From Paragraph 19:
"...והנה הקשר כפול שרגילין לעשות... יש מחמירין לומר דזהו קשר של קיימא אם מניחו לעשרים וארבע שעות... אבל באמת מנהג אבותינו תורה היא..."
"...And behold, the double knot that we are accustomed to make... there are those who are stringent to say that this is considered a permanent knot if one leaves it for twenty-four hours... But in truth, the custom of our ancestors is Torah..."
From Paragraph 20:
"...רואים אנו שכל העולם קושרים מנעליהם בקשר כפול ומתירין אותם בלי שום פקפוק... ואיך נניח את ישראל חס ושלום למכשול? אלא ודאי שאין בזה שום איסור..."
"...We see that the entire world ties their shoes with a double knot and unties them without any hesitation... And how can we leave Israel, Heaven forbid, to stumble? Rather, it is certain that there is no prohibition in this at all..."
From Paragraph 27:
"...ולפיכך המתר קשר שאינו עשוי להתקיים לעולם, אף על פי שהוא קשר כפול, פטור ומותר לכתחילה... וזהו יסוד גדול להציל את המון עם ה' מאיסור..."
"...Therefore, one who unties a knot that is not made to remain forever, even though it is a double knot, is exempt and it is permitted ab initio... And this is a great foundation to rescue the masses of the nation of God from prohibition..."
Close Reading
To fully appreciate the legal architecture Rabbi Epstein builds, we must slow down and analyze his arguments step-by-step. His analysis is not merely a collection of practical rulings; it is a highly structured, conceptually daring re-evaluation of the metaphysics of Shabbat labor. We will explore this through three distinct insights: structural progression, key terminology, and existential tension.
Insight 1: Structural Progression - From Talmudic Archetypes to Modern Realities
To trace the structural progression of Rabbi Epstein’s argument from paragraph 19 through paragraph 21, we must look at how he bridges the vast historical gulf between the ancient agricultural world of the Talmud and the domestic life of his 19th-century congregants.
In the classical Talmudic framework found in Babylonian Talmud, Shabbat 111b, the archetypes of biblically forbidden knots are the kesher gamalim (the camel-driver’s knot) and the kesher sapanim (the sailor’s knot). These are heavy-duty, professional knots tied with specialized ropes, designed to withstand immense tension and remain intact indefinitely.
[Talmudic Archetypes] ---------> [Medieval Codifiers] ---------> [Arukh HaShulchan]
- Camel-driver's knot - Temporal thresholds - Functional teleology
- Sailor's knot - 24-hour vs. 7-day rules - Living communal custom
- (Highly professional) - (Strict/Formalistic) - (Dynamic/Relational)
Rabbi Epstein begins paragraph 19 by acknowledging these classical categories, but he immediately pivots to a modern, domestic equivalent that vexed the codifiers of his era: the "double knot" (kesher כפול or kesher al gabai kesher—a knot tied directly on top of another knot).
He structures his argument as a conceptual funnel:
- The Abstract Standard: He first presents the strict view of earlier authorities (such as the Chayei Adam), who ruled that if a double knot is left intact for more than twenty-four hours, it retroactively becomes a kesher shel kayamah (a permanent knot), rendering its creation a rabbinic or even biblical violation of Shabbat.
- The Practical Crisis: In paragraph 20, Rabbi Epstein points out a glaring sociological reality: almost every Jew in Eastern Europe ties their shoes with a double knot and unties them without a second thought. If the strict view is correct, then the entire Jewish world is desecrating Shabbat on a weekly basis.
- The Halakhic Resolution: In paragraph 21, he resolves this tension by redefining the relationship between the physical act of tying and the human intention of duration. He argues that a double knot on a shoe is structurally different from a camel-driver’s knot. The shoe knot, by its very nature and the habits of the wearer, is meant to be temporary. By shifting the focus from a rigid, twenty-four-hour countdown to the inherent function of the garment, Rabbi Epstein systematically dismantles the stringency of the earlier codifiers.
Insight 2: Key Terminology - "Kesher Shel Kayamah" vs. "Ma'aseh Uman"
To understand the mechanics of Rabbi Epstein's leniency, we must analyze the interaction between two vital halakhic terms that define the prohibition of tying on Shabbat:
- Kesher Shel Kayamah (קשר של קיימא): A permanent knot.
- Ma'aseh Uman (מעשה אומן): A craftsman's or professional's knot.
In paragraphs 22 and 23, Rabbi Epstein deep-dives into how these two criteria intersect. He references the classic formulation of the Rambam in Mishneh Torah, Sabbath 10:1, which states that a knot is biblically forbidden only if it is both a kesher shel kayamah (permanent) and a ma'aseh uman (professional). If it is permanent but made by a layman (ma'aseh hedyot), or if it is a professional knot but meant to be temporary, it is only rabbinically forbidden.
MA'ASEH UMAN (Professional) MA'ASEH HEDYOT (Layman)
+---------------------------------+---------------------------------+
KAYAMAH | | |
(Permanent) | BIBLICALLY FORBIDDEN | RABBINICALLY FORBIDDEN |
| | |
+---------------------------------+---------------------------------+
TEMPORARY | | |
| RABBINICALLY FORBIDDEN | COMPLETELY PERMITTED |
| | |
+---------------------------------+---------------------------------+
Rabbi Epstein introduces a brilliant, highly nuanced reading of what constitutes "permanence" (kayamah). He challenges the temporal formalism that dominated the works of many post-Shulchan Arukh commentators. For many of these commentators, "permanence" was defined by a ticking clock:
- Less than 24 hours = Temporary (permitted).
- Between 24 hours and 7 days = A gray area of rabbinic doubt.
- More than 7 days = Permanent.
Rabbi Epstein argues that this temporal taxonomy is fundamentally flawed when applied to everyday household items. In paragraph 23, he asserts that kayamah is not an objective measurement of elapsed time, but a subjective state of human intent coupled with the functional teleology of the object.
For example, if a person ties a double knot on a sack of flour with the intention of keeping it closed until the flour runs out in a month, that is a kesher shel kayamah because its function is permanent. However, if a person ties a double knot on their shoe and, out of sheer laziness, does not untie it for a week, that knot does not become a kesher shel kayamah. Why? Because the shoe is an item of clothing, and clothing, by definition, is designed to be put on and taken off. The inherent nature of the shoe defines the knot as temporary, regardless of the wearer’s temporary laziness.
By prioritizing the functional nature of the object over a rigid, temporal stopwatch, Rabbi Epstein provides a revolutionary way to understand halakhic reality.
Insight 3: The Existential Tension - Halakhic Formalism vs. Living Practice
In paragraphs 25 through 27, the text reaches its emotional and intellectual climax. Here, we witness the profound tension between halakhic formalism—the desire to construct a perfectly closed, mathematically consistent legal system—and the living, breathing reality of the Jewish community.
Rabbi Epstein was deeply sensitive to the spiritual toll that over-stringency takes on the average person. If the laws of Shabbat are presented as so complex and restrictive that a person cannot even tie their shoes or open a sack of food without committing a sin, the average person will eventually experience spiritual fatigue. They may either abandon observance altogether or live in a state of constant, paralyzing anxiety.
To prevent this, Rabbi Epstein deploys his most powerful halakhic weapon in paragraph 27: the principle of limud zechut (finding merit). He asserts:
"ומזה יש לימוד זכות גדול על מה שנוהגין עתה להקל..."
"And from this there is a great merit for that which we are accustomed to be lenient nowadays..."
He argues that the community's intuitive behavior is not a sign of ignorance or laxity, but is itself a form of oral tradition. Because the community knows that these knots are untied eventually, the community’s collective consciousness has already categorized them as temporary.
Furthermore, Rabbi Epstein links the labor of Kosher (tying) to its twin labor, Matir (untying). He notes that the Mishnah in Mishnah Shabbat 15:1 establishes that any knot that one is permitted to tie on Shabbat, one is also permitted to untie. By establishing that double knots on clothing and everyday items are conceptually temporary and therefore permitted to be tied, he simultaneously rescues the community from the prohibition of untying them.
His ruling is a masterclass in rabbinic responsibility. He refuses to allow a formalist stringency to transform a joyful day of rest into a day of legalistic dread.
Two Angles
To appreciate the uniqueness of Rabbi Epstein’s approach, it is highly instructive to contrast his view with that of his contemporary, Rabbi Yisrael Meir Kagan, in the Mishnah Berurah.
=============================================================================================
Halakhic Axis Mishnah Berurah (Rabbi Yisrael Meir Kagan) Arukh HaShulchan (Rabbi Yechiel Michel Epstein)
---------------------------------------------------------------------------------------------
Primary Metric Objective Temporal Thresholds Functional Teleology & Intent
(Strict 24-hour / 7-day clock) (The inherent nature of the object)
Double Knots Highly stringent; views them as Permissive; views them as temporary
on Shoes potentially rabbinically forbidden by definition since shoes are meant
if left tied over Shabbat. to be put on and removed.
Halakhic Philosophy Protective formalism; builds fences Pastoral realism; seeks "limud zechut"
to prevent accidental transgression. to align law with intuitive practice.
=============================================================================================
Angle 1: The Mishnah Berurah’s Objective-Temporal Approach
The Mishnah Berurah in Mishnah Berurah 317:1 adopts a highly cautious, defensive posture. Heavily influenced by the Chayei Adam, the Chafetz Chaim rules that the primary metric for defining a "permanent knot" is time.
If a knot is tied with the intention of remaining intact for more than twenty-four hours, it immediately enters a zone of rabbinic prohibition. If it is meant to remain for more than seven days, it is treated as a severe rabbinic or even biblical issue.
Therefore, according to the Mishnah Berurah, if you tie a double knot on your shoe on Friday afternoon and do not plan on untying it until Sunday morning, you have violated Shabbat. The Mishnah Berurah prioritizes objective, quantifiable time to create a clear, protective boundary (seyag) around the laws of Shabbat, ensuring that no one inadvertently crosses into biblical desecration.
Angle 2: The Arukh HaShulchan’s Functional-Teleological Approach
In contrast, the Arukh HaShulchan rejects this strict temporal clock as the sole arbiter of halakha. Rabbi Epstein argues that a human being is not a robot controlled by a stopwatch. Instead, he views the world through a phenomenological lens.
A shoe is an item of clothing; clothing is inherently dynamic and temporary. Therefore, any knot tied on a shoe is structurally and conceptually "temporary" because its ultimate purpose is to be untied, regardless of whether a particular individual lazily leaves it tied for days.
For Rabbi Epstein, the Mishnah Berurah's 24-hour rule is an "excessive stringency" (choumarah yeteira) that ignores the teleology of human garments. The Arukh HaShulchan prioritizes the lived reality and common sense of the community, refusing to let abstract mathematical time override the functional meaning of human actions.
Practice Implication
How does this conceptual debate shape our actual, physical observance of Shabbat today? The insights of the Arukh HaShulchan provide a highly practical, anxiety-reducing framework for navigating modern domestic life.
Consider three common Shabbat scenarios:
1. Double-Knotted Athletic Shoes and Children's Shoes
It is highly common for parents to tie their children’s shoes with tight double knots to prevent them from tripping, or for runners to double-knot their sneakers. Often, these knots are left tied for days or even weeks.
- According to the strict view of the Mishnah Berurah, untying a double knot that has been left intact for several days is a serious halakhic problem, as the knot may have retroactively acquired the status of a permanent knot (kesher shel kayamah).
- According to the Arukh HaShulchan, however, because a shoe is fundamentally designed to be put on and taken off, the double knot remains conceptually "temporary" in its essence. If a double knot on a shoe becomes tight or tangled on Shabbat, you may untie it without hesitation or guilt, as the functional identity of the shoe overrides the elapsed time.
2. Garbage Bags and Trash Can Liners
When taking out the trash on Shabbat, we often pull the drawstrings of a garbage bag and tie them in a tight double knot before placing the bag in the bin.
[Garbage Bag Tie] ----> Never to be untied ----> "Permanent" by intent ----> FORBIDDEN TO TIE
[Shoelace Tie] ----> Meant to be untied ----> "Temporary" by nature ----> PERMITTED TO TIE
Here, the Arukh HaShulchan’s focus on intent and teleology cuts both ways:
- Because the garbage bag is being thrown into the dumpster and will never be untied, tying a double knot on it is a permanent act. Even though the bag's active life in your hands is short, the knot is meant to remain forever.
- Therefore, under Rabbi Epstein’s framework, one must avoid tying a tight double knot on a trash bag on Shabbat. Instead, one should tie a simple slipknot (a bow) or use a single fold, which is not structurally permanent.
3. Twist Ties and Plastic Bread Bags
We often encounter plastic bread bags closed with paper-wrapped wire twist ties. Is twisting a wire considered "tying" (Kosher)?
Applying the Arukh HaShulchan’s logic, a twist tie on a loaf of bread is designed to be opened and closed repeatedly throughout the week as one eats the bread. It has no professional craftsmanship (ma'aseh uman) and is completely temporary in its function. Therefore, twisting and untwisting a bread bag tie is entirely permitted on Shabbat, as it lacks both the structural permanence and the professional nature required to violate the Melacha.
Chevruta Mini
To deepen your understanding and prepare for a vibrant discussion with your study partner, explore these two challenging questions that surface the profound tradeoffs within Rabbi Epstein's methodology:
Question 1: The Limits of Intent vs. Physical Structure
Rabbi Epstein argues that the functional teleology of an object (e.g., a shoe is meant to be taken off) can prevent a physical double knot from being classified as permanent, even if it is left tied for weeks.
- The Tension: If human intent and the object's function are this powerful, where do we draw the line? If a person ties a double knot on a temporary outdoor shelter (like a Sukkah canvas) with the explicit intent to take it down in two weeks, does the physical tightness of that professional-grade knot become "temporary" and permitted to be tied on Shabbat?
- The Tradeoff: At what point does an objective, physical structure override our subjective intentions? If we rely too heavily on the "intent of untying," do we risk transforming the objective physical boundaries of the 39 Melachot into purely psychological states?
Question 2: The Authority of "Minhag" (Custom) and Pastoral Leniency
In paragraph 20, Rabbi Epstein famously uses the phrase "מנהג אבותינו תורה היא" (the custom of our ancestors is Torah) to justify the common practice of tying double knots on shoes.
- The Tension: What is the active ingredient in this legal justification? Is the custom of the community authoritative because the masses possess an intuitive, holy understanding of the law, or is the rabbi simply using legal brilliance to reverse-engineer a defense for a practice that the community would refuse to change anyway?
- The Tradeoff: If a halakhic authority always seeks to find a limud zechut (meritorious defense) for common practice, how does the law retain its power to challenge, refine, and elevate human behavior? When should a rabbi say, "The community is simply wrong and must change," and when should they say, "The community's behavior is Torah"?
Takeaway
The Arukh HaShulchan teaches us that the structures we build on Shabbat are defined not merely by their physical form, but by their functional relationship to human life, communal rhythm, and the ultimate purpose of creation.
