Additional Notes for Class 2

Addendum on Origins of Mishna Berurah and Aruch Hashulchan: We spoke during Class 2 about the Mishna Berurah and the Aruch Hashulchan, but we did not have time to discuss the mysterious origin of how the Aruch Hashulchan came to be published and why some sections are missing from the set. See this link for an interesting article on that topic. I would add to this article that as recently as 1992 some missing sections were discovered, so it is possible that the remaining missing sections will still be found and the set will someday be complete. (The parts still missing are on Nedarim, vows – not a heavily traversed area of Halacha anyway.) The different ways in which the Mishna Berurah and Aruch Hashulchan came to be published might explain why the MB tends to be learned more nowadays than the AHS.

A word about the Levush: We did not talk about the Levush during the class because the world at large does not consider the Levush to be on the level of the books that we did discuss. However, as I think the Levush is highly underrated, I will add a word or two here about the Levush. In the fascinating introduction to the Levush, the author, Rabbi Mordechai Yaffe, a contemporary of Rav Yosef Karo, describes how he came to write his own work. He says that he began writing his own “Shulchan Aruch,” shortening the Tur and Beit Yosef for people to have an easier time learning. Then he heard that Rav Yosef Karo himself was working on such a work, so he stopped, believing that it would be better for the original Beit Yosef to shorten his own work than for someone else to do it. When Rav Karo’s Shulchan Aruch was finally released, Rabbi Yaffe writes, he was highly disappointed, as Rav Karo did not give any reasons or background for what he was writing, relying entirely on the Tur and Beit Yosef. As Rabbi Yaffe complains in the introduction, Rabbi Karo makes it seem as if the Halachot fell from the sky without any reason or basis behind them. So Rabbi Yaffe went back to writing his own version, but then he heard that the great Rav Moshe Isserles in Krakow was working on a project that would modify the Shulchan Aruch, and Rabbi Yaffe assumed this would be primarily to add reasons and background to the Shulchan Aruch. When the Rama finally released his work, Rabbi Yaffe saw that this, too, was inadequate, as it served primarily to correct the Shulchan Aruch for Ashkenazim and not to add reasons for the Shulchan Aruch’s own words. So Rabbi Yaffe went back yet again and completed his Levush. This history is to make the point that the advantage in learning the Levush is that, in contrast to the Shulchan Aruch, the Levush always gives the reason for every Halacha, and yet without going into as much debate or discussion as the Tur before him or the Aruch Hashulchan after him. His purpose is not to analyze Halacha from the prism of whether it is quoted correctly in the first place in the Tur and Beit Yosef, but simply to add reasons that the Halachot are what they are. He even follows the Shulchan Aruch’s order, not just in the Siman (chapter) but even in the Seif (paragraphs). If he wants to add something original, he does it at the end of an existing Seif, rather than mix us up by adding a new Seif and thus changing the numbering and order that the Tur and Shulchan Aruch had already devised. By maintaining the order of the Shulchan Aruch but adding in reasons (which he maintained makes it easier to learn and remember Halachot), the Levush becomes a great, readable resource, either on its own or as a companion volume to the Shulchan Aruch.
The name “Levush” (the full set is really called “Levush Malchut”) is based on words from Pesukim in Megillat Esther. The Levush is subdivided into sections with matching names – Levush HaTechelet on the beginning of Orach Chaim, Levush HaChur on the later parts of Orach Chaim, Levush Ateret Zahav on Yoreh Deah, Levush HaButz V’ha’argaman on Even Ha’ezer, and Levush Ir Shushan on Choshen Mishpat. There are also several parts of the set of Levush on other topics, such as Levush Ha’orah on Rashi’s Chumash commentary, Levush Pinat Yikrat on Rambam’s Moreh Nevuchim, and a super-commentary on Rikanati’s Chumash commentary, Levush Even Yikrah. There are ten “Levushim” in all. The non-Halachic ones, he explains in the introduction, he wrote in the years that he was waiting for Rav Yosef Karo and Rav Moshe Isserles to produce their own works, which he ultimately found disappointing.

Halacha – Comparing MB and AHS

Additional Notes for Class 3

1) Ein Mishpat Ner Mitzvah: Regarding the authorship of the navigational tools, this link describes briefly the life of Yehoshua Baruch (16th century Italy), who compiled three important navigational tools – Ein Mishpat Ner Mitzvah (Gemara –> Halacha), Torah Ohr (Gemara –> Tanach), and Mesoret HaShas (cross references between similar sugyot within the Gemara). It is interesting that although today we have a combined “Ein Mishpat Ner Mitzvah,” it was originally compiled as two separate glosses and was only combined later. Here is a screen-grab from HebrewBooks from a 1548 printing of the Gemara, which would make this about the earliest insertion of the Ein Mishpat / Ner Mitzvah on the page. Notice that all the way on the left is “Ein Mishpat,” which, when needed, informs us that a particular Halacha (“Heivi’u Lifanav Pat …”) can be found in Rambam Perek 3 of Hilchot Berachot and Tur Orach Chaim Chapter (Siman) 240. But there is also “Ner Mitzvah,” closer to the Gemara text, which informs us that the same Halacha is #292 (I assume in Masechet Berachot). Keep reading below the picture.

Halacha Early Ein Mishpat Ner MitzvahNow here is the same page in a modern-day Gemara, with the combined Ein Mishpat Ner Mitzvah. Keep reading below the picture.

Halacha New Ein Mishpat Ner Mitzvah

Comparing the two pages of Gemara, there are many things to notice: The Ner Mitzvah component has indeed been combined with the Ein Mishpat into a single gloss on the left side of the page, but the 292 number has been replaced with the number 35. It seems that over time, the numbers went from continuing through the entire volume to instead enumerating the Halachot chapter by chapter. Furthermore, there are many changes to the gloss itself. The words with the Ein Mishpat and Ner Mitzvah in the earlier printing (“Heivi’u Lifanav Pat …”) do not have Ein Mishpat Ner Mitzvah on the new page, but the same reference in Rambam and Tur/Shulchan Aruch is now pointed to from earlier words on the same page (“Aval Itay …”). Where there was only one Ein Mishpat and Ner Mitzvah reference on the earlier version of this page, there are now seven, so clearly much emendation of the Ein Mishpat has taken place over the centuries. Not to mention the fact that the earlier references to “Tur” have now given way to “Tur and Shulchan Aruch,” because the Shulchan Aruch was first printed in 1563 and this earlier printing of the Gemara page was from 1548! So again, quite a lot has happened to the Ein Mishpat and/or Ner Mitzvah over the centuries. What seems to have started out as a considerably more modest project to highlight the major Halachic decisions on the page (hence only one reference on the 1548 page) mushroomed over time to include every possible Halachic decision on the page, including ones that might be very tangential to the overall flow of the Gemara’s discussion (hence seven references on the new page). Even today, each new edition of the Gemara seems to unearth new Halachic references on the page which become added to the Ein Mishpat Ner Mitzvah on the side of the page.

2) Be’er Hagolah: It turns out the compiler of the Be’er Hagolah, the notes which send the reader from the page of Shulchan Aruch (or Mishna Berura) backwards to the source of the Shulchan Aruch’s words, was Rabbi Moshe Rivkash (1640-1672), who lived a very fascinating (and very tragic) life. See this link to read about him.

3) Gemara Page: As a review of the major features and tools on the Gemara page, check out this nice (if technically dated) web page (link). Mouse over the page and click to learn about the different features of the Gemara page.

4) Beracha in a new place during a meal: We touched on the subject of whether a new beracha needs to be made if one moves to a new place during a meal. Although various opinions and scenarios are presented in Tur and Shulchan Aruch (remember, same order) Orach Chaim (the part about daily routine) Siman (Chapter) 178, the Rama (for Ashkenazim) in Seif (Halacha) #2, as explained by Mishna Berurah #26, differentiates between one who was previously eating bread and one who was eating fruits or other non-Birkat Hamazon foods. In the first case, one knows when he leaves that he will be returning for Birkat Hamazon, so his leaving is not considered a break (hefsek) in the meal and he does not make a new beracha. If he is eating fruits or vegetables or drinking something, on the other hand, which do not require one to return to where he started to say Borei Nefashot, he is considered to have made a hefsek by leaving and he would therefore need to make a new She’hakol. See later on the same page of Gemara that we were discussing during the class, Pesachim 101a, which is Page 6b of the handouts.
