Description

🔥 Brushing teeth on Shabbos – four primary halachic approaches – Issue is multi-faceted: **Memareiach**, **Sechitah**, **Hachanah**, **Refuah**, **Melabein**, **Uvdin d’chol**, **Chavalah** are all discussed in the literature. – **View 1 – Rav Soloveitchik / Rav Hershel Schachter**: – Permits **normal toothbrushing** on Shabbos with: – Regular toothpaste – Wet toothbrush – Rinsing the toothbrush afterward – Memareiach: Unlike smoothing a surface, brushing does not **grind down/smooth the teeth themselves**, only removes plaque. – Hachanah concern (washing toothbrush “for after Shabbos”): – Rav Schachter said it is **for cleanliness and Shabbos oneg**, not to prepare for after Shabbos (e.g., to avoid spouse being upset at a messy bathroom on Shabbos). – **View 2 – Rav Ovadia Yosef**: – Allows **wet toothbrush** and **regular toothpaste**. – Requires a **designated Shabbos toothbrush** to avoid **Uvdin d’chol** (weekday-like behavior). – Advises **not washing the toothbrush** afterward due to **Hachanah** concerns. – **View 3 – Rav Shlomo Zalman Auerbach / Rav Elyashiv (Rav Elyashiv Weinberg cited)**: – Forbids **regular toothpaste** due to **Memareiach**. – Allows **liquid toothpaste**. – Not particularly concerned with **Sechitah** when using liquid toothpaste. – **View 4 – Rav Moshe Feinstein** (followed by Rav Willig in practice): – Forbids using **any paste/gel** due to **Memareiach** when the paste is spread over the teeth. – Squeezing toothpaste from the tube is **not the issue**; the issue is smoothing it on the teeth. – Forbids **wetting the toothbrush** before brushing because of **Sechitah**. – Forbids **washing off the toothbrush** afterward because of **Hachanah** (preparation for post-Shabbos use). – Recommended method: – Put **mouthwash** in the mouth. – Use a **dry toothbrush** to brush while the mouthwash is in the mouth. – Avoid turning on **hot water** (Bishul concerns). – Do **not** rinse off the toothbrush after. 💼 Office Mincha with a Gerer chassid who skips Tachanun at Mincha – **Gerer minhag**: Not to say **Tachanun at Mincha** (ever). – If the **minyan location “belongs” to the Gerer** (e.g., his office, or he “owns/runs” the place): – “Ba’al habayis, minhago” – he can set the **minhag of that place**. – Others generally follow that minhag, as with a Sefardi-run minyan factory where **Birkat Kohanim is daily**; Ashkenazi Kohanim participate since the hosts’ minhag governs. – If it is **not his space** and the minyan is more “neutral”: – One person’s private minhag (e.g., a single Gerer) **should not override** the general minhag of the group. – It is appropriate to have others **daven for the amud** so Tachanun is not regularly dropped. – Distinction from Rav Shlomo Zalman: – If a place has a **real minhag not to say Tachanun**, one follows that minhag. – If Tachanun is skipped **simply to shorten davening** with no minhag basis, one should **say Tachanun** anyway. 🕍 Wearing a tallis over the head – who, when, and where in davening – **Source and status of Atifa (covering the head with tallis)**: – Gemara in Kiddushin and Magen Avraham: – **Unmarried men** do **not** do **Atifas haRosh**. – Atifa originally associated with **Talmidei Chachamim / distinguished people**. – Gemara in Berachos: **Kos shel beracha with zimun** requires Atifa. – By **kal vachomer**, **devarim shebikdusha** (which require a minyan) should also have Atifa. – Common practice: – **Shemoneh Esrei** and **Kaddish / Borchu / Kedusha** said with **Atifa** for a married man. – **Krias Shema and Atifa**: – Beis Hillel: **“Kol adam korei kidarko”** – Shema can be recited **in whatever body position you are already in**. – Since one may not insist on a specific **Amidah** (standing) position for Shema, Atifa, which parallels Amidah for devarim shebikdusha, is also **not required**. – Taz and Midrash: Hashem does **not burden** Klal Yisrael to say Shema specifically **standing and with head covered** as would be required for a royal proclamation; **any posture is acceptable**. – **Rav Chaim / Brisker minhag as transmitted by Rav Soloveitchik and Rav Schachter**: – Tallis **over head** (Atifa) for: – **Kaddish** – **Borchu** – **Kedusha** – **Shemoneh Esrei** – Tallis **off the head** for: – **Birchos Krias Shema** – **Krias Shema** itself – Reasons: – Fulfill **“Kol adam korei kidarko”** for Shema. – Allow **Tefillin shel Rosh and the Kesher** to remain **visible**, in line with “**V’rau kol amei ha’aretz ki Shem Hashem nikra alecha** – these are the Tefillin shel Rosh.” – **Other devarim shebikdusha** and Atifa: – In general, **devarim shebikdusha** require **Amidah and Atifa** unless they take the form of a **pasuk or bracha**, in which case the **“Shema model”** applies and they can be without. – This explains why **kerias haTorah**, though a devar shebikdusha (requires a minyan), does not require standing or Atifa for each listener. 🛏️ Learning Torah while lying down – Gemara in Berachos: Torah should be learned **“b’eimah, b’yirah, b’retet, u’v’zeiah”** – with awe, seriousness, and exertion. – Rav Schachter’s father: word is **“zeiah” (sweat)**, not “ze’ah” (trembling), indicating **physical exertion / ameilus**. – Ideal posture and demeanor should reflect **kavod haTorah** and focused effort, rather than a relaxed, lounging attitude. – Gemara in Megillah: – In times of Rabban Gamliel, Torah was learned **standing**; after his death, people weakened and began to learn **sitting**. – Rashi calls the shift from standing to sitting a **reduction in kavod haTorah**. – Hence, in principle, **standing** is the highest standard; **sitting** is a concession; **lying down** is a further reduction in formal kavod. – However, there is also value in **having Torah on one’s mind even when lying down**: – While resting / going to sleep, it is better to **occupy the mind with Torah** than with nonsense or nothing. – **Hirhur (thinking) in Divrei Torah** is certainly permissible in any posture. – Practical balance: – **Core learning sessions** should be done in a manner reflecting **seriousness and effort** (not lying down). – When one **already needs to lie down** (e.g., for rest, bedtime), it is positive to **read/think Torah** at that time. 📚 Considering a career in chinuch (Jewish education) vs. financial concerns – Two simultaneous responsibilities in guidance: – **Encourage** those who are genuinely suited for chinuch. – **Discourage** those who are not appropriate for it. – When a person: – Has **talent and desire** for chinuch, – But is **paralyzed by financial uncertainty** and needs a clear, predictable pay path, – This often reflects either: – A **lack in bitachon (trust in Hashem)**, or – A **rigid personality** that cannot tolerate financial ambiguity. – If one is **unable** to get over this “bitachon hump,” chinuch may **not be a viable path** for that individual. – Observed outcomes: – Most people who entered chinuch and were reasonably suited **do not regret it**, and their families had their basic needs met (food, schooling, etc.), though often **without luxuries** such as expensive vacations. – Some leave chinuch later, but conversely some **leave other careers** (e.g., law) to go **into** chinuch for greater meaning. – Rav Silver’s practical guidance (re: choosing between law school and chinuch): – Law: clear, structured **career trajectory**, salary ladder, partner track. – Chinuch: often **no clear trajectory**, but: – There can be periods of **significant stability** (e.g., secure positions in schools and shuls). – One’s actual career path may be **much more expansive** than imagined (e.g., ending up teaching at **Beis Midrash / Semicha level**, which might never have been anticipated). – Hashkafic point: – “Those who take care of Hashem’s children, Hashem takes care of them.” – Communities often **value and seek to support** excellent mechanchim respectfully. – Broader reality check: – **No field** is fully secure today; **AI and economic shifts** can destabilize even previously “safe” professions. – Thus, fear of instability should be weighed against the fact that **other fields also lack guarantees**. 🕯️ Havdalah candle – is a single braided wick acceptable? – Halachic ideal: **Avukah** for Havdalah. – Gemara in Pesachim: Mitzvah Min HaMuvchar to use an **avukah**. – Rambam: defines avukah as **a strong, multi-flame light**. – Shulchan Aruch (O.C. 298:2): – “Mitzvah min hamuvchar le’varech al avukah.” – If one does not have an avukah, some say to **light a second candle and join them**. – Rema: **Any candle with two wicks** already has the halachic status of an **avukah**. – Mishnah Berurah: **Better** for the avukah to be a **wax candle**, but still focused on having **multiple wicks**. – Status of a **single braided wick**: – Technically, the bracha on the fire is **on any visible flame**, so one can be yotzei with a **single flame**. – However, the **“mitzvah min hamuvchar”** is specifically a multi-wick avukah. – A single braided wick is **not** an avukah in the strict sense, but it does provide **a larger, more substantial flame** than a thin single wick. – Therefore: – One **fulfills Havdalah** with such a candle. – But le’chatchila, a **two-wick candle** is preferred to fulfill the **ideal of avukah**. 🎄 Buying kosher foods with non-Jewish holiday themes (e.g., “Christmas tree” cookies) – Products like **kosher Christmas-themed cookies** are common in Western markets. – Halachic core: – They are **not actual avodah zarah** and not direct **korbanos / offerings** to avodah zarah. – Primarily a **marketing and design choice** tapping into local culture and season. – Discomfort vs. prohibition: – Many would find **hosting or serving** such items (e.g., “Merry Christmas” napkins) in a shul or Jewish home **inappropriate** due to the **religious messaging and symbolism**. – However, issuing a blanket **issur** is difficult because the item itself is not a religious act nor a direct support of avodah zarah. – Practical: – Halachically **not clearly forbidden**. – Best practice in many communities: **avoid** overt Christmas-themed items out of **kavod Yisrael and distance from foreign religious imagery**. 📜 Violating website “Terms of Service” (ToS) – halachic status – When a user clicks **“I agree”**: – This creates a **binding commitment** under **“hin shel tzedek”**: – Torah requires one’s **“yes” to be a real yes** and one’s **“no” to be no**; obligations created by one’s declarations and clicks must be honored. – **Intellectual property** aspects: – Many ToS are designed to protect **copyrights, usage rights, and proprietary data**. – Rav Willig’s approach (as reported): these are governed by **Dina deMalchusa Dina** (the law of the land). – If secular law recognizes the ToS and protects the company’s intellectual property, **halacha obligates compliance** via Dina deMalchusa. – Conclusion: – Intentionally violating ToS after agreeing is **halachically problematic** due to: – **Breaking one’s word (“hin tzedek”)**. – **Violating Dina deMalchusa** in areas such as IP and contract law. 📖 When Mishnah Berurah brings a dispute – how should a layperson decide? – **Baseline**: – Most of halacha (**“99%”**) is non-controversial; learning Shulchan Aruch and Mishnah Berurah gives strong guidance on the majority of cases. – When encountering a **machlokes** in the Mishnah Berurah: – Step 1: **Check minhag ha’olam**: – See how **frum communities actually practice** in that situation. – If there is a consistent minhag, that is often the **default path**. – Step 2: If **no obvious minhag** (rare/special case): – Ask **your Rebbe / Rav**; that is what Rebbeim are for. – Step 3: For someone who **themselves is a Rebbe / Rav**: – Even then, one ideally consults **older Rebbeim** when possible. – Where that is not possible, one investigates **sources and seforim**, understands **each side’s reasoning**, and decides based on the **stronger argument and weighting of authorities**. 🎧 Are mosh pits “Chukas HaGoyim”? – **Definition** (dictionary): Area near a stage where people **jump, thrash, and deliberately collide** while listening to music. – Halachic framework of **Chukas HaGoyim**: – **Smag**: Practices that are **“Me’yuchad lahem”** (distinctly theirs) are problematic. – **Gra**: Focus on practices tied to **idolatrous worship** (e.g., trees in churches). – **Maharik / Beis Yosef**: – Two main issues: – Acts of **Pritzus** (licentiousness). – Practices **with no rational explanation** – suspected **remnants of avodah zarah**. – If there is **no logical reason**, assume it may be **idolatry-based**. – Applying this to **mosh pits**: – Origins: late **197s Southern California punk scene**, later spreading to Washington, D.C., Boston, New York, and into metal, grunge, EDM, and hip-hop. – Purpose: a **high-energy, intense physical expression** of the music for youth with lots of energy; essentially a **social/entertainment phenomenon**, not a religious ritual. – Therefore, it does **not appear to be rooted in avodah zarah**. – As such, it is probably **not Chukas HaGoyim** in the strict halachic sense. – Other halachic and hashkafic issues: – Documented as being **violent** enough that: – Some venues **ban** it. – Some performers have been **arrested** for inciting it. – Injuries and property damage can occur. – Halachically: – **Assur to harm others** or put them in **unreasonable danger**. – If damage occurs (e.g., torn clothing, injuries), there may be issues of **nezek** (damages). – There is a possible argument of **implicit mechilah / assumption of risk** (similar to Purim damage halachos) where everyone entering knows and accepts the risk, but that is a complex Choshen Mishpat discussion. – Hashkafically and practically: – Even if not Chukas HaGoyim, it is likely **not an appropriate practice** to organize or join, given **violence, danger, and lack of refinement**.Support this podcast at — https://redcircle.com/ten-minute-halacha/donationsAdvertising Inquiries: https://redcircle.com/brandsPrivacy & Opt-Out: https://redcircle.com/privacy

Chapter 1: What is the main topic discussed in this episode?

0.858 - 18.934 Rabbi Jonathan Cohn

Okay, everybody, welcome back to another week of Answering Your Shailas. And again, all of these shiurim should be lezchus rufu shalema for Yonatan Eitan Ben Basheva Bracha, our dear friend, Rabbi Jonathan Cohn, Joko, he shall have a rufu shalema b'soch sharchol Yisrael, and we thank him so much.

18.914 - 39.365 Rabbi Jonathan Cohn

for the idea of this year, for implementing it, for pushing me to do it, for arranging all the questions, for putting together a team of people who help arrange all the questions. Thank him for everything that he does with this and all of his other wonderful, wonderful work. So let's begin right away. Question number one.

Chapter 2: What are the halachic considerations for brushing teeth on Shabbos?

39.445 - 42.97 Rabbi Jonathan Cohn

What are the halachs of brushing one's teeth on Shabbos?

43.01 - 67.307 Rabbi Aryeh Lebowitz

This question for me is like... It's what they call a layup. The very first article I ever wrote, the very first major halachic topic that I ever researched in a significant way is brushing teeth on Shabbos. I wrote an article more than 20 years ago. probably close to 25 years ago in the Journal of Halachic and Contemporary Society on brushing teeth on Shabbos.

67.387 - 93.53 Rabbi Aryeh Lebowitz

I've since translated that article into Hebrew and published it in my Hakona Olamo Chela Gimel on Shabbos. But essentially, we'll try to keep it brief. Essentially, there are several, many, many issues that come up with brushing teeth on Shabbos. It is a very dynamic topic. You have to talk about mimareach, you have to talk about tzchita, hachana, refuah, melabein, uvduduchol, chavala.

93.79 - 103.444 Rabbi Aryeh Lebowitz

So I remember at the time that I was researching the topic, I remember Rav Shechter had told me that he holds, and Rav Solveitchik held, that you're allowed to brush teeth on Shabbos, normally, with regular tooth.

103.424 - 126.16 Rabbi Aryeh Lebowitz

toothpaste and with water and everything and cleaning off the toothbrush afterwards so I remember I put together a list of all of the of all the issues and I went over to Rav Shachten and I went through one by one why does Rav Yehold this is not an issue why does Rav Yehold that's not an issue At the end of the day, there are four basic shitos about brushing teeth on Shabbos.

126.18 - 145.046 Rabbi Aryeh Lebowitz

Opinion number one is one I just referred to, Rav Salveitchik and Rav Schechter, that hold that it's absolutely moot to brush teeth on Shabbos, even with a wet toothbrush, even with regular toothpaste, and you could wash the toothbrush off after brushing. I asked, why isn't it hachanah? Ramesh holds it's hachanah to wash the toothbrush off. After brushing, Rav Shechter said, I have nine children.

145.426 - 163.811 Rabbi Aryeh Lebowitz

If we all had left dirty toothbrushes in the bathroom, my wife would get angry at us on Shabbos. It wouldn't wait until after Shabbos. So it's not a hachana for after Shabbos. It's so that she doesn't get upset on Shabbos that we have left a mess all over the bathroom. So that's the way Rav Shechter said it.

163.951 - 185.622 Rabbi Aryeh Lebowitz

Now, you have to really go through the sugyas to understand the other issues, why it's not memarech and why it's not... why it's not sochit. In Nefsh HaRav, I think it says that they told Rav Soloveitchik that Rav Moshe holds that you're not allowed to brush teeth on Shabbos because it's memachek.

186.083 - 205.908 Rabbi Aryeh Lebowitz

And Rav Soloveitchik said if it were memachek, then when you brush your teeth a hundred times, you wouldn't have any teeth left. Because memachek means that you're scraping down a surface in order to smooth it out. So we may be cleaning the plaque off of our teeth, but we're not scraping down the surface itself in order to smooth it out. Of course, Rav Moshe didn't mean memachik.

Chapter 3: What do different rabbinic authorities say about brushing teeth on Shabbos?

697.452 - 724.753 Rabbi Aryeh Lebowitz

So the minig is therefore also to say Shmon Asher with Atifah, because the Pasuk says, That's a Pasuk in Tehillim. So it says, that a person is, when he's engaged in tefillah, he has an atifah. So that's as far as, like Kaddish and Kedushah, and as far as Shmona Esrei. So those things should have a proper atifah, a person should have the talus over their head, if they are a married person.

724.773 - 745.665 Rabbi Aryeh Lebowitz

What about kriyashma? So kriyashma could be different. There is a Mishnah in Brachos, in Daffy Laman Beis, that quotes the Sheet of Beis Hillel, that everyone could say kriyashma, however they prefer to say it. So you're allowed to say kriya shema, standing, sitting, lying down, walking, whatever you want. They still learn this from lech t'cha v'derech.

745.685 - 770.624 Rabbi Aryeh Lebowitz

Lech t'cha v'derech is however you happen to be. Beishamai says, no, v'shachachav kumecha, that when you're saying kriya shema shel avis, you need to lie down. When you're saying kriya shema shel shach, you need to sit up. Now, according to Beis Hillel, you're not allowed to even be makbid to assume a particular position during Kriya Shema. You go as is.

772.567 - 793.66 Rabbi Aryeh Lebowitz

Now, normally, Dovah Shabbat Kedushah requires both Amida and Atifa. Over here we see, according to Beis Hillel, Kriya Shema, you're not allowed to be makbid on Amida. You just have to be as is. Well, if you're not makbid on Amida, then you're not makbid on... on Atifa either. And therefore, Kriya Shema, there's a good argument to be made, does not require Atifa.

794.02 - 816.359 Rabbi Aryeh Lebowitz

The Taz in Ar Chayim Simuchas quotes a Medrash that describes that HaKadosh Baruch Hu told Bnei Yisrael that he doesn't burden Klal Yisrael with saying Shema while standing on their feet and with their heads uncovered like you would normally have to do when you're reading like a major declaration of a king or something like that. But, however you are, you come as is to Kriya Shema.

816.86 - 836.311 Rabbi Aryeh Lebowitz

Sitting, standing, with Atifa, without Atifa, it's all good. So, Rav Shechter always quotes from the Rav, in the name of Rav Chaim Salveitchik, in the name of his grandfather. that he would wear his talus with atifa for Kaddish and for Baruch Hu and Kedusha, but he would take it off of his head for Kriya Shema, and then do atifa again for Shemona Esrei.

836.671 - 846.45 Rabbi Aryeh Lebowitz

So when it came time after Yishtabach for Kaddish and Baruch Hu, he had his talus over his head, he'd have his talus over his head again for Shemona Esrei, but in between it fell off.

846.43 - 874.446 Rabbi Aryeh Lebowitz

he would definitely take it off during Kriya Shema as a fulfillment of another reason Rav Shechter points out to take the towels off your head during Kriya Shema is in order to expose the Tfilin Shal Rosh and the Kesher of the Tfilin Shal Rosh because the Gemara Menachem says and Rav Lazar Hagadol says so it's supposed to be the Tfilin Shal Rosh it's supposed to be visible

874.426 - 890.786 Rabbi Aryeh Lebowitz

And L'chaora, the same would apply to Kriyas HaTorah, because Kriyas HaTorah is equated with Kriyashma when it comes to Atifa, because the... You don't need a midah during Kriya Shema because Kol Adom Korik Adarko.
