Daf Yomi Eruvin: Lesson
Class description

Eruvin 2a and Eruvin 2b, presenting the first debates about the acceptable height and width of the opening of a mavoi, a private space shared by several other joint private spaces, and whether those dimensions are derived from the Beit HaMikdash.

August 12, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 4a and Eruvin 4b, a new suggestion for the reason 20 amot was the limit on height of the korah at the opening of a mavoi, why a Mishnah had to say it about both Sukkah and mavoi, and then where amot in halakhah are made up of 5 or 6 tefahim.

August 13, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 4a and Eruvin 4b, whether amot being all 6 tefahim is a debate of tannaim or universally accepted (Abbaye/Rava), the idea of many fundamental issues–measurements, barriers to immersion, construction of walls– are halakhah le-Moshe mi-Sinai, given to Moshe at Sinai separately from the Torah, and what those are, and then about how to fix a korah that’s too high.

August 14, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 5a and Eruvin 5b, issues of the height of the korah, the beam at the entryway of the mavoi, how to raise the floor, how much floor to deepen if it’s less than ten, the minimum length of a mavoi, how long a lehi (post) can be and still be valid, and whether rules of mavoi can be derived from rules for hatzer, courtyards.

August 14, 2020 7:30 pm - 8:30 pm
Daf Yomi Eruvin: Lesson
Class description

Eruvin 6a and Eruvin 6b, mostly about breaks in alleyway walls, particularly a mavoi akum, an L-shaped (or U-shaped) mavoi, where the third wall of each segment has a break in it at the corner, and how to treat that. We encounter in that context the idea of bakei bah rabim, if lots of foot traffic goes through an opening, it cannot be considered a break in a wall, it is considered open. We closed with the beginning of the discussion of taking two stringencies of different rabbis, and how that is not considered optimal halakhic behavior.

August 16, 2020 11:30 am - 12:30 pm
Daf Yomi Eruvin: Lesson
Class description

Eruvin 7a and Eruvin 7b, the cases where combining stringencies is allowed or is foolish, and then alleyways that verge on other open spaces, whether used or unused, and whether or not they then open onto a public space.

August 18, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 9a and Eruvin 9b, some more korah issues– it has to be above or within the mavoi itself, can use lavud from both walls, as well as havut rami, see an elevated korah as coming down into the space, and then a move to lehi issues, whether  the people in the mavoi can carry within the space opposite the post as well, whether the mavoi abuts a reshut ha-rabim, a highway or public market, or a karmelit, and then how being visible only from the outside or only from the inside affects matters.

August 19, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 10a and Eruvin 10b, finishing up the issue of nir’eh mi-bahutz ve-shaveh mi-bifnim, whether walls visible from outside an area but not inside can count as walls, thence to how wide R. Yehudah would have allowed an opening of a mavoi to go, with the contrast case of pasei bira’ot, a four cornered area Hazal allowed for drawing water from a well, and then to how we close off extra space of a mavoi entrance, depending on atei avira de-hai gisa u-de-hai gisa, air on both sides nullifying a post, and omed merubbah al ha-parutz, whether solid material has to be more than empty space to nullify it, or just equal to it.

August 20, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 11a and Eruvin 11b, the uses of a tzurat ha-petah, the shape of a door, and the possibilities of it even covering up for parutz merubah, more open space than solid material, with some relationship between the wall for kil’ayim, mixing types of produce, for Shabbat, and for mezuzah.

August 21, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 12a and Eruvin 12b, the ways to close off a mavoi or a hatzer, the difference between them, what qualifies as a reshut hayahid at a Biblical level, and how to define a mavoi as opposed to a hatzer, an alleyway as opposed to a courtyard. Plus some leniencies around water.

August 22, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 13a and Eruvin 13b, identifying the student who would quote R. Yishmael to R. Akiva, seeing how R. Meir studied with both, and why, and how brilliance expresses itself, and why we follow Beit Hillel for halakhic purposes.

August 23, 2020 11:30 am - 12:30 pm
Daf Yomi Eruvin: Lesson
Class description

Eruvin 14a and Eruvin 14b, odd shaped korot, beams at the opening of mevo’ot, and some rules of lehi, including a rare occasion we follow Abbaye rather than Rava.

August 25, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 16a and Eruvin 16b, a lot about how we construe unenclosed space, where we treat it as if its enclosed or at least not a problem, first for the question of parutz ke-omed, if the enclosed space is exactly the same amount as the unenclosed, and then with walls we construct where lavud fills in the unenclosed space and how far we can push that.

August 26, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 17a and Eruvin 17b, finishing up our discussion of when we can use walls made up of just rope or just pickets, leading into a discussion of whether the definition of the eruv happens at Shabbat for that entire Shabbat, or problems that arise can be problems even for that Shabbat, and then ending the chapter with leniencies for armies, including not needing to make certain eruvin. Then starting the next chapter, about the posts we make to allow drawing from a well.

August 27, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 18a and Eruvin 18b, whether the permission of using corner-posts to “enclose” a watering hole applies to cisterns or tanks or only natural water wells, whether public or private, and then a series of statements by R. Yirmiyahu b. Elazar, a rare amora.

August 28, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 19a and Eruvin 19b, finishing up the series of statements of R. Yirmiyah b. Elazar, who moves into the acceptance of Divine judgment, leading into a bunch of digressions on who does or does not recognize Gd’s justice as just, who does or does not repent, and the names of Gehinnom. Then, back to Eruvin issues, in terms of the corner posts of a well and how to fix them if there is too much space, and what materials qualify as corner posts.

August 30, 2020 11:30 am - 12:30 pm
Daf Yomi Eruvin: Lesson
Class description

Eruvin 21a and Eruvin 21b, on the use of pasei bira’ot (and burgenin–guard huts that allow extending a city to not yet start counting the tehum of 2000 amot) outside of Israel, and then aggadeta about the importance of Torah, rabbinic law, and Torah scholars.

Daf Yomi Eruvin: Lesson
Class description

Eruvin 22a and Eruvin 22b, what it takes to become a Torah scholar, the limit of beit se’atayim for corner posts around a well, the effect of public traffic on walls for a reshut ha-yahid, whether man-made or natural, and then back to what kinds of bodies of water can be included in pasei bira’ot, four corner posts around.

September 1, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 23a and Eruvin 23b, the ruling on pasei bira’ot needing to be around a public source of natural water, the issue of the shape of an enclosure that’s not hukaf le-dirah, not enclosed for living in it, (and whether it needs some kind of living space), how we got to the idea of 50 by 100, or 5000 square amot, from the Mishkan, and what happens when some of an enclosed space is planted like a garden.

September 2, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 24a and Eruvin 24b, many configurations of how a karfaf, an area not originally enclosed for people to live in and use, could or could not be used for carrying within it, and how to re-enclose such areas to now make them fit for human habitation.

September 3, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 25a and Eruvin 25b, ways to rectify an area too large to be used with walls that were not originally placed there to make it a living space, either by reducing the space or by building a new wall, and how distinct it has to be. Or, by a pi tikrah yored ve-sotem, the lip of a ceiling can count as a wall coming down, and then when a karfaf borders on human inhabited spaces and how those work.

September 4, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 26a and Eruvin 26b, figuring out the right way to have fixed the Reish Galuta’s shaded pavilion to be able to carry from the house out there on Shabbat, what kinds of walls do or do not count as hukaf le-dirah, for human use, then how one is mevatel reshut, relinquishes ownership rights in a joint area on Shabbat, closing chapter Osin Pasin. Next chapter starts with the kinds of foods we can use in an eruv tehumin, shittuf mevo’ot, and–for Rashi– an eruv hatzerot.

September 5, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 27a and Eruvin 27b, the idea that rules stated generally in the Mishnah frequently have exceptions, even when the Mishnah itself listed some exceptions. On the substance of the Mishnah, salt water was a plausible candidate for use in an eruv or for purchase with ma’aser sheni money (a matter of debate), leading us to the idea of havla’ah, including something in a purchase price without naming it specifically, leading to a long discussion of subsidiary items permitted to be purchased with ma’aser sheni money (like the container for wine). And more.

September 6, 2020 11:30 am - 12:30 pm
Daf Yomi Eruvin: Lesson
Class description

Eruvin 28a and Eruvin 28b, how different rabbis wielded the principle of kelal u-perat u-kelal, meaning how to generalize from the specific examples in a verse, and then what foods do or do not count as food for an eruv, the requirement of edibility for an eruv as opposed to for tum’at okhlin, the ritual impurity of foods, and then about how much food is needed for an eruv.

September 7, 2020 11:30 am - 12:30 pm
Daf Yomi Eruvin: Lesson
Class description

Eruvin 29a and Eruvin 29b, many foods and the amounts of them needed for an eruv, with the surprising information that foods used as a part of a meal can qualify for an eruv in the amounts they would be used as the part of the meal. We don’t need two full meals worth of side dishes, in other words, but the amounts of those side dishes we would eat at a meal.

September 8, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 30a and Eruvin 30b, on whether and when personal standards affect halakhic issues– so, e.g., an elderly person needs to use only the smaller amounts of food s/he eats as the size of a meal in his/her eruv, but a person with a large appetite follows the usual standard. Then, about how having taken an oath prohibiting a certain food affects its use in an eruv, and the views of Beit Shammai and Sumkhos as to how plausible it has to be for the person to be able to eat the food in the eruv.

September 9, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 31a and Eruvin 31b, in the context of figuring out how a kohen could or could not put terumah in a cemetery for an eruv, three concepts: mitzvot performance is/is not considered hana’ahhalakhic benefit, an eruv tehumin should be set up only for mitzvah purposes (or not), and once an eruv establishes residence, it is or is not any longer of interest to the owner. Then, to foods whose halakhic status might make them inaccessible, like untithed produce at a rabbinic level, and, finally, messengers who cannot put the eruv down for us.

September 10, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 32a and Eruvin 32b, several attempts to prove we can trust messengers to do what they undertook, whether observant Jews will violate halakhah in a relatively minor way to protect a less observant Jew from a more significant violation, and the issues in putting an eruv tehumin in a tree, both in terms of sharing a space with the eruv and using the tree, a matter of whether Rabbinic rules apply even bein ha-shemashot, as Shabbat enters.

September 11, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 33a and Eruvin 33b, the complications of putting an eruv on a tree when the branch is outside of the four amot of the base of the tree, and the person intends his/her place of resting on Shabbat to be at that base.

Daf Yomi Eruvin: Lesson
Class description

Eruvin 35a and Eruvin 35b, other versions of how a locked closet could or could not be ok for the eruv inside, then where a problem arises with the eruv, especially if we don’t know if the problem happened before or after bein ha-shemashot.

September 14, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 36a and Eruvin 36b, on how we evaluate safek situations, situations of doubt, particularly when the doubt is about when a certain status changed, when a presumed status helps us with the eruv, as well as the principle of the eruv needing to have been defined before it took effect. Then, moving on to bererah and the ervu, to whether a Jew can set up one or multiple eruvin and only later have events define which or whether the eruv took effect.

September 15, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 37a and Eruvin 37b, bererah, bererah, and more bererah, when a later event can be considered to reveal what happened at an earlier time, such as setting an eruv up and only later deciding when it takes effect, setting up a tithing situation to be defined only later, and more.

September 16, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson

Eruvin 38a and Eruvin 38b, whether holidays and Shabbat that abut each other count as one long sanctity (so eruvin have to be for both or neither) or two separate ones, allowing switching the eruv from one to the other, with the prohibition of hakhanah, preparing from one day of sanctity to another.

September 17, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 39a and Eruvin 39b, more examples of where we can or cannot treat 2 days of holiday as separate sanctities, allowing for setting up separate eruvin or taking terumah to be used on the second day. Rosh HaShanah is a questionable case, and the issue of 2 days of holidays outside Israel comes up as well.

Daf Yomi Eruvin: Lesson
Class description

Eruvin 42a and Eruvin 42b, what happens to food and people that are taken out of their original tehum, their original defined 2000 amot, and/or then returned, unwittingly or deliberately.

Daf Yomi Eruvin: Lesson
Class description

Eruvin 45a and Eruvin 45b, when people who leave their Shabbat boundaries for permissible reasons can go all the way back or only two thousand amot, with or without their weapons, depending on what kind of war, what kind of city, and whether they won or lost.  Then on to questions of establishing a tehum without realizing it, for objects and people.

Daf Yomi Eruvin: Lesson
Class description

Eruvin 46a and Eruvin 46b, proving R. Yohanan b. Nuri does think objects acquire Shabbat boundaries even without an owner, the idea that we always follow the lenient view in eruvin and in mourning, even though in Rabbinic issues we would usually follow the majority (as we prove from sources about niddah and about mourning). Then we move to rules of whom we follow in halakhic disputes, it being a matter of the person rather than the ideas.

September 25, 2020 10:15 am - 11:15 am
Daf Yomi Eruvin: Lesson
Class description

Eruvin 47a and Eruvin 47b, trying to prove or disprove the ideas of decision rules for which tanna we follow in disputes, and then trying to establish whether the property of non-Jews develops a tehum as Shabbat or Yom Tov starts.
