Iyunim B’hilchos Shabbos Summer Zman 2021


Me-Think of shir hashirim as a metaphor for the relationship between HKBH and the Jewish people as he asks us to stay one more day after sukkot


Chaver-This version might be more appropriate, if after 7 days of Sukkot you might be Running on Empty.


Me- Outstanding! I’ve been running on empty and running behind so long but at least I do know what I’m hoping to find

HaRav Asher Weiss: Sunday 4/11/21-הקדמה להלכות קידוש בשבת

Is kiddush something we do to be a mkadeish Shabbat or is it simply acknowledging the kedusha?

Interesting points include: does saying good shabbos count as kiddush? (no); When the S”A says tzarich does it mean only lchatchila?; and Mitzvat dibbur only requires ikkar dibbur to be yotzeih.

HaRav Meir Tzvi Spitzer: Tuesday 4/13/21-טעימה בכוס של ברכה

Is the requirement to taste from the kos shel bracha due to bracha lvatala concerns or because it’s gnai not to?  It may depend on the nature of the kos shel bracha.

HaRav Shlomo Cynamon: Wednesday 4/14/21-יסוד דין קידוש ביום ולילה

There’s no issue of mitzvot chavilot on birchat hakos if there’s a relationship between the subjects of the bracha.  The kos as hatchalat haseuda may also avoid this problem.

A kos shel bracha may always need a bracha achrona even if a shiur hasn’t been drunk.

HaRav Simcha Bunim Londinsky: Thursday 4/15/21-בענין קידוש

Is kiddush a shevach to HKBH a formal bracha or zechira balma?  Some would say just saying “good shabbos” is enough to be mkayem the mitzvah.  Have in mind (or is this stam daat) not to be yotzeih kiddush in the amidah or you might have an issue being motzi others.  When does a woman’s chiyuv for kiddush start in the a.m.?

HaRav Asher Weiss: Sunday 4/18/21-קידוש במקום סעודה

What food counts for kiddush bmakom seudah?  Is it a din in seudah or kiddush?  Perhaps the reason for allowing kiddush on mezonot in shul is because it’s considered the beginning of your meal at home.

Great side point—R’Weiss’s shul allows only one standard kiddush for all!

HaRav Michoel Frank: Tuesday 4/20/21-בענין יקנה”ז

Yaknahaz—why the differences of opinion over ordering of these brachot?  Are kiddush and havdala really one bracha?  Implications include:  Sitting vs. standing, use of bread and women saying havdala.

HaRav Shraga Kallus: Wednesday 4/21/21-עיונים בהלכות קידוש

Kiddush bmakom seudah—what is makom? Does it change by house to house, room to room, or corner to corner?  Does seeing or intent help?  What counts for seudah? (focus on sushi!)

HaRav Dovid Zucker: Thursday 4/22/21-קידוש על ידי שומע כעונה

Can a mother be yotzei kiddush (duraita) with shomea koneh through her son who was recently bar mitzvah (chazaka draba only works drabanan)?

Are women chayav in seudah?  There are halachic implications (e.g., forgot addition in birchat hamazon).

HaRav Asher Weiss: Sunday 4/25/21-חמר מדינה לקידוש והבדלה

Can chmar medina be used for havdala, evening kiddush or daytime kiddush (lchatchila or bdieved)?  R’Weiss believes there is no chmar medina today due to changes in eating patterns.  Grape juice works like wine!

HaRav Yehoshua Goldstein: Tuesday 4/27/21-בין קידוש להבדלה


Analysis of the Rambam on the nature of kiddush and havdala on shabbat and yom tov.

HaRav Shlomo Gottesman: Wednesday 4/28/21-ל”ג בעומר ולשמחה מה זה עושה

History of the relationship between Lag Baomer, R’Shimon bar Yochai and the Arizal.  Was it a Yahrtzeit or a day of simcha?

HaRav Shraga Kallus: Thursday 4/29/21-עיונים בהלכות הבדלה

Wine is always preferred, he still likes orange juice as chmar medina (since used daily).

HaRav Asher Weiss: Sunday 5/2/21-איסור מלאכה לפני הבדלה

Is not working/eating before havdala a din in kedushat Shabbat (keeping longer) or in havdala (similar to not starting to eat when it’s time to daven)?

HaRav Shraga Kallus: Thursday 4/29/21-עיונים בהלכות הבדלה

All the usual suspects in defining bein hashmashot.

HaRav Refoel Kahn: Tuesday 5/4/21-תשלומים להבדלה

If one forgot to make kiddush Friday night, do they make it on Shabbat as tashlumin or as a deferred completion?  What does one do about havdala if one was an onein on Shabbat?

HaRav Shraga Kallus: Wednesday 5/5/21-עיונים בהלכות הבדלה – ב’

Is havdala duraita or drabanan?  Is one chayav in havdala if they don’t keep Shabbat?  Other items discussed include:  Obligations of women and children; Standing vs. sitting; Telephone usage; and Eating or drinking before havdala.

HaRav Zev Smith: Thursday 5/6/21-ברכת בשמים בהבדלה

Besamim and ner are not intrinsic to havdala but are associated enough not to cause a hefsek.  Various applications discussed (e.g., early and late havdala).

HaRav Asher Weiss: Sunday 5/9/21-=הקדמה לתוספת שבת ויום טוב

Analysis of the general nature and requirement for tosefet Shabbat.

HaRav Yosef Elefant: Tuesday 5/11/21-ביסוד דין תוספת שבת ודברי חיזוק מעניני דיומה

Nature of tosefet yom tov—is it a complete switchover, an issur mlacha or a chalot shem yom tov (vs. things done on yom tov)?

HaRav Yitzchok Sorotzkin: Sunday 5/16/21-בדין תוספת שבת ויום טוב ודברי בתעוררות

Meron lessons plus a rerun of the TFNS debate.

HaRav Elya Brudny: Sunday 5/16/21-דברי התעוררות לשבועות

Fine for eretz yisrael and the mikdash.

HaRav Shraga Kallus: Wednesday 5.19.21-עיונים תוספת שבת ויום טוב

The gemara posits four possible definitions of bein hashmashot which quickly multiply into many possible actual applications.  Some leniencies discussed.

HaRav Meir Tzvi Spitzer: Thursday 5/20/21-קבלת שבת בתוספת

Accepting tosefet Shabbat has many extra-halachic benefits.  Then the general TFNS discussion.

HaRav Asher Weiss: Sunday 5/23/21-עיונים בקבלת שבת מקודם

R’Weiss is in favor of making early shabbos when circumstances are appropriate and explains how to properly do so.

Interesting side point—the radvaz says the magid mishneh is the best source for understanding the rambam’s thinking.

Also included—what is the nature of tosefet Shabbat?



HaRav Dovid Zucker: Tuesday 5/25/21-I Made Early Shabbos – Can I Ask Someone Who Didn’t To Do Melacha?


Why can I ask a ben brit who hasn’t accepted Shabbat yet to do a mlacha but amira lakum is forbidden?

HaRav Shraga Kallus: Wednesday 5/26/21-עיונים בקבלת שבת ויום טוב

There are a number issues with making early Shabbat (which is why the minhag in aretz is generally not to).  Some workarounds provided herein.

HaRav Simcha Bunim Londinsky: Thursday 5/27/21-עוינים בקבלת שבת מקודם

Yes, there are concerns with making early Shabbat (tartei dsatrei, kiddush timing, morning zmanim) but there is a long standing practice to daven maariv early on erev Shabbat as well.

HaRav Lipa Geldwerth: Sunday 5/30/21-דברי פתיחה

The aron kodesh defied the basic laws of physics, implying that there was no relation to gashmiut (physicality).  Torah to us is involuntary, like breathing.

HaRav Noach Isaac Oelbaum: Sunday 5/30/21-ביסוד חיוב מעשה ופעולת מלאכת שבת

Is melechet Shabbat defined based on the totza (result) or maaseh (act)? Specific applications discussed
HaRav Asher Weiss: Sunday 5/30/21-הקדמה לסוגיה: ריבוי בשיעורים

Marbeh bshiurim—is it duraita or drabanan?  Is there a difference in application in pikuach nefesh vs. ochel nefesh?  Is it hutra or dchuaya?  Is there a difference in definition in different mlachot (e.g., those defined by quantities)?

Smoking is forbidden, those in authority who don’t speak out against it will be called to account.

HaRav Nisan Kaplan: Monday 5/31/21-עיונים בריבוי בשיעורים ומעשה שבת

R’Moshe’s psak allowed for ribui shiurim in carrying a pack of cigarettes even though only a few were needed. (Does this extend to a key ring with a car key on it?  The chofetz chaim allowed carrying ancillaries with one’s gun on Shabbat for Cantonists.)  Is the heter one of a general nature or only because any one of the items might be the one you use?

HaRav Shlomo Cynamon: Monday 5/31/21-דברי פתיחה


More on ribui shiurim.  Focus on the gmar mlacha by bishul vs. that of other mlachot.

HaRav Yitzchok Lichtenstein: Monday 5/31/21-בדין ריבוי בשיעורים

Focus on maaseh Shabbat issues when done by a ben brit vs. a non-ben brit.  What’s the chashash that drives the knas and how does that inform on the applications? (e.g., Shabbat day vs. motzai Shabbat, what usages and by whom?)

HaRav Shraga Kallus: Wednesday 6/2/21-עיונים בהלכות מעשה שבת

More on maaseh Shabbat issues with a particular focus on mazid vs. shogeig and applications involving chilonim and baalei tshuva.

HaRav Shlomo Gottesman: Thursday 6/3/21-Egged, El-Al, and the Tram: Maaseh Shabbos?

There are real life applications of maaseh Shabbat issues (e.g., meizid, mumar, msayea, shinui bguf hadavar, amira lakum bshvilcha).

How can you board an El AL flight motzai Shabbat if you know the plane was prepped on Shabbat?  Given that the newspaper is printed on Shabbat, how can you read it?  Israeli public work projects (trains, light-rail, highways) if built on Shabbat, how can you use them?  Money quote—poskim were asked to “please come up with a heter.”

HaRav Asher Weiss: Sunday 6/6/21-יסוד דין מעשה שבת

Maaseh Shabbat issues reviewed.  Interesting approaches to motzai Shabbat airplane flights (it’s shaat hadchak?!) and public works projects (“they” can’t assur our trains).

HaRav Shraga Kallus: Wednesday 6/9/21-עיונים בריבוי בשיעורים ומעשה שבת

Marbeh bshiurim issues including:  Duraita vs. drabanan (and implications), and does marbeh’s definition vary by the mlacha/topic covered and material type involved?

HaRav Meir Tzvi Spitzer: Tuesday 6/8/21-מעשה שבת הלכה למעשה א

Maaseh Shabbat with focus on heterim for cows milked on Shabbat as well as train usage.

HaRav Dovid Zucker: Thursday 6/10/21-בדין ריבוי בשיעורים

Marbeh bshiurim—the duraita/drabanan and hutra/dchuya analysis.

HaRav Asher Weiss: Sunday 6/13/21-הקדמה לחשמל בשבת

Is electricity on Shabbat molid/drabanan (first generation poskim) or boneh/duraita (2nd generation)?  It’s probably better not to give specific technical explanations for the prohibition because people will argue the point (and if you say it’s uvda dchol you might as well say it’s a mutav).  We know it was like a bat kol/daat torah confirmed that it’s prohibited.  R’Weiss presents his maakeh bpatish explanation for the issur.

HaRav Meir Tzvi Spitzer: Tuesday 6/15/21-מעשה שבת ב’: חשמל בשבת

Possible heteirim for using electricity generated in eretz yisrael on Shabbat.

HaRav Shraga Kallus: Wednesday 6/16/21-עיונים בחשמל בשבת

Introduction to electricity on Shabbat—molid vs. boneh with focus on binyan bkeilim.

HaRav Dovid Zucker: Thursday 6/17/21-בדין ריבוי בשיעורים ב

Part II of ribbui bshiurim focusing on analysis of heating water for brit/mother.

HaRav Shraga Kallus: Wednesday 6/23/21-Electrical Appliances: Halacha Lmaaseh

Modern refrigerators have all kinds of Shabbat issues, this shiur focuses on the traditional compressor/thermostat and lights issues.  Issues include:  Koach rishon; Grama; Psik reisha; Eino mtkavein; Mlechet machshevet . . .  Is a change in electric current a mlacha??  Also, covered—motion sensors (better not to know) and elevators.
