1 Grinshpan, Yehuda, Ḥiyukha shel torah (Jerusalem, 1993)Google Scholar, 78. Regarding a portrait of Shneur Zalman's grandson, the writer Alexander Ziskind Rabinowitz (1854–1945; known by the acronym of his name, “Azar”) commented, “It is better for us to honor the words of our sages rather than their pictures.” Alexander Ziskind Rabinowitz, “Toledot mishpaḥat Shne'urzohn,” He-’asif 5 (1889), 167. Cf. Hazofe, November 23, 2007, 11 (translated partial transcript of a 1969 talk by Rabbi Joseph B. Soloveitchik, regarding the image of Shneur Zalman). While Azar and Grinshpan emphasized written legacy over portraiture, Soloveitchik waxed on the value of the (alleged) portrait of Shneur Zalman.

Posner suggested alternatives under the rubric of what he termed “judicial studies”—namely, “studies of a person's works with only incidental reference to his life” and “studying [the judge's] opinions, philosophy, style, legacy, and influence.” It seems that the sum total of judicial studies of a jurist, together with more than incidental references to his life, might add up to a worthy judicial biography.

14 To cite a few examples: I. A. Benjacob listed Shulḥan ‘arukh ha-rav and Shneur Zalman's other writings, omitting the role of Shneur Zalman's sons in the posthumous publication of their father's work. Benjacob, I. A., Oẓar ha-sefarim (Vilna: Rom, 1880)Google Scholar 139, 586, 587, 588. Samuel Joseph Fünn noted how unique it was that Shneur Zalman authored a code, though he mistakenly wrote that Shneur Zalman “published a number of sections of it.” Fünn, Samuel Joseph, Kenesset yisra'el (Warsaw: Zaks and Ẓukermans, 1886–1890), 331–33Google Scholar. In Fünn's entry for Shneur Zalman's son, Shneur Zalman's name appears as “Shne'ur Shlomo Zalman” and no mention is made of the son's role in the publication of the code. Ibid., 187. J. D. Eisenstein's encyclopedia lists only the 1854 edition of Shulḥan ‘arukh ha-rav, with no mention of Shneur Zalman's other legal works. Eisenstein, J.

26 Shulḥan ‘arukh begins Passover laws with bedikat ḥameẓ, the pre-Passover ritual where householders check that there is no forgotten leavened bread in the house. Shulḥan ‘arukh, oraḥ ḥayim 431:1. In contrast, Shneur Zalman opens with the biblical commandment and its rabbinical development that gave rise to the bedikat ḥameẓ ritual. Shulḥan ‘arukh ha-rav, oraḥ ḥayim 431:1–5. On the naming conventions of these two works, see note 36 below and accompanying text.

27 This distinction is reflected in the arrangement of laws: Shulḥan ‘arukh begins with the ideal course of action (lekhatḥila) and then considers post factum situations (bedi‘avad); Shulḥan ‘arukh ha-rav, with its educational goal, opens with the core elements of the requirement before considering later rabbinic embellishments or cautionary fences. Zevin's example is the time for morning prayers. Compare Shulḥan ‘arukh, oraḥ ḥayim 89:1 with Shulḥan ‘arukh ha-rav, oraḥ ḥayim 89:1.

28 In the section dealing with tort, Shneur Zalman ruled that one may not cause bodily harm to another, even where the would-be claimant expresses consent, explaining, “For a person does not have any ownership over his body to injure it.” The rule against harming one's own body appears in earlier sources; Shneur Zalman's articulation teaches a principle—a person's relationship to his or her body—in addition to the law. Shulḥan ‘arukh ha-rav, ḥoshen mishpat, hilkhot nizkei guf ve-nefesh ve-dineihem, 4.

29 In discussing the prohibition against erecting a tent on Sabbath, Karo did not include definitions for the pertinent legal categories “tent” and “temporary tent”; such definitions are offered by Shneur Zalman. Compare Shulḥan ‘arukh, oraḥ ḥayim 315:1, with Shulḥan ‘arukh ha-rav, oraḥ ḥayim 315:1.

30 Regarding preparations for the Passover seder, Shulḥan ‘arukh directs a person to set the table before the onset of the festival “in order to eat as soon as it gets dark . . . because it is a religious ideal to hasten and to eat so that the children will not fall asleep.” Shulḥan ‘arukh, oraḥ ḥayim 472:1. Shneur Zalman changed the wording: “in order to begin the seder as soon as it gets dark . . . because it is a religious ideal to hasten to begin the seder so that the children will not fall asleep.” Shulḥan ‘arukh ha-rav, oraḥ ḥayim 472:1. All agree that seder rituals and recounting the Exodus story precede the meal; Shneur Zalman's language is more precise.

31 E.g., explanations for disqualification of ḥameẓ (leavened bread that is forbidden on Passover) that was not disposed of before the onset of the festival, Shulḥan ‘arukh, oraḥ ḥayim 448:3; Shulḥan ‘arukh ha-rav, oraḥ ḥayim 448; for celebrating two days of Rosh Hashana, Rashi to Babylonian Talmud, Rosh Hashana 30b; Rosh to Rosh Hashana 4:14; Yaakov b. Asher, Arba‘ah turim, oraḥ ḥayim 600; Shulḥan ‘arukh ha-rav, oraḥ ḥayim 600:4; for rules for Gentile agency on Sabbath, Meir b. Yekutiel, Hagahot maymoniyot, hilkhot shabbat 6:2; Shulḥan ‘arukh ha-rav, oraḥ ḥayim 243:1.

32 E.g., the Sabbath prohibition against moving a plant potted in a container without holes, Shulḥan ‘arukh ha-rav, oraḥ ḥayim 336:12; the status of the day after Shavuot, ibid., 494:19.

33 E.g., the requirement to extend Yom Kippur beyond its official end. Ibid., 608:1. Shneur Zalman's innovative approach on this point has been discussed in Lubavitch literature before and after Zevin: Ha-tamim, no. 6 (1937): 620–21; Mondshine, Sifrei ha-halakhah, 31–33 (Hebrew numbers); Alashvili, Avraham, “Derashot ḥazal ‘al ha-pesukim be-shulḥan ‘arukh admor ha-zaken,” Pardes Chabad, no. 9 (2003): 93–95Google Scholar.

The kabbalistic elements should be examined for originality, e.g., Hilkhot talmud torah 1:4, 2:2, 2:9, 4:3–6. Apart from Ashkenazi's volume, see Shraga Faitel Ha-levi Levin, “Be-hilkhot t[almud] t[orah] le-’ad[mor] ha-z[aken],” Or Hadorom 1, no. 2 (1984): 11–30Google Scholar; Moskovits, Ḥayim, “Keiẓad ‘ḥokrim’ ḥasidut be-yameinu,” Heichal Habesht, no. 29 (2010): 179–84Google Scholar; Tworek, Wojciech, “Setting Times for Torah Study in R. Shneur Zalman of Liady's Thought,” Association for Jewish Studies Review 38, no. 1 (2014): 29–57Google Scholar. In an analysis reminiscent of Zevin's work, Levin highlighted five unique aspects of Shneur Zalman's Hilkhot talmud torah: practical instruction, novelty, explanation, precision, and compilation.

39 For Tchernowitz's example, compare Shulḥan ‘arukh, oraḥ ḥayim 25:1; Shulḥan ‘arukh ha-rav, oraḥ ḥayim 25:1–2. Alas, Shneur Zalman is not consistent in his grammatical choices; e.g., his treatment of the word makom in Shulḥan ‘arukh ha-rav, oraḥ ḥayim (masculine—mahadura tinyana 1:7, 2:2, 3:6, 3:7, 3:11, 4:1, mahadura kama 3:20, 4:3, 8:16, 10:13, 92:7, 164:2, 178:6, kuntras aḥaron 75:2; feminine—mahadura tinyana 2:1, kuntras aḥaron 75:1). See, however, Yehoshua Mondshine, “Tevila be-mei ha-da‘at,” He‘arot u-vei'urim, no. 753 (1998): 38; ibid., no. 755 (1998): 102–03. Shneur Zalman's insistence on correct grammar is highlighted in connection to his Siddur. For example, see his brother's approbation to the 1822 edition of the Siddur. Zevin, Soferim u-sefarim, 3:333–35.

40 Tchernowitz's example is that instead of the traditional but anachronistic term for the supplicatory prayers—nefilat appayim, literally meaning “falling on the face”—Shneur Zalman used the term taḥanun, meaning “supplication.” Shulḥan ‘arukh, oraḥ ḥayim 429:2; Shulḥan ‘arukh ha-rav, oraḥ ḥayim 429:8. Unfortunately, Tchernowitz overlooked numerous instances where nefilat appayim or its derivatives are used. Shulḥan ‘arukh ha-rav, oraḥ ḥayim 108:5, 111:3, 131, 292:7.

46 E.g., Zevin observed that Shulḥan ‘arukh ha-rav notes the legal sources of laws, a feature that does not necessarily appear in other codes. Alashvili dedicated his third essay to this feature. Rather than comparing the feature to other codes, Alashvili examined Shneur Zalman's language in presenting those legal sources and identified where Shneur Zalman departed from earlier sources. Alashvili then boldly presented the legal implication of the alterations.

49 E.g., deciphering Kuntras aḥaron, Shneur Zalman's in-depth excursuses that supplement the code. The endeavor to identify the sources of the code resulted in the series entitled Mar'ei mekomot ve-ẓiyunim by Nissan Mangel (three volumes, 1969, 1973, 1974), Mordekhai Shmuel Ashkenazi (1971), and Levi Bistritsky (1974, 1975, 1977). In 1976 these publications (except for Bistritsky's 1977 volume) were reprinted in a single volume, together with an index of Shulḥan ‘arukh ha-rav prepared by Aharon Chitrik in 1965. Bistritsky also published two volumes under the title Leket ẓiyunim ve-he‘arot le-shulḥan ‘arukh admor ha-zaken (1982, 1986). This project culminated in a new edition of Shulḥan ‘arukh ha-rav (see below). Regarding Ashkenazi's first volume, see Yisrael Alfenbein and Moshe Marinovsky, “‘Akhshav efshar lada‘at ma be-’emet pasak admor ha-zaken,” Aspaklarya, no. 1231, April 20, 2007, 24.

50 Levin was also editor of and a regular contributor to the New York Yagdil torah; in 2003 he published a volume on Shneur Zalman's laws for Passover, and in 2006 he published a volume about how to instruct a Gentile to do work for a Jew on Sabbath according to Shneur Zalman. Levin's two-volume Dover shalom contains comments on specific rulings in Shulḥan ‘arukh ha-rav. Video and audio recordings of Levin's lectures on Shulḥan ‘arukh ha-rav, mostly in Yiddish but also in Hebrew and in English, together with source sheets, and multiple-choice exams are available at http://video.chasidut.net/videos/load/levin, www.chabadlibrary.org/shiurim, www.chabadlibrary.org/mivchanim, accessed December 11, 2014.

83 E.g., the latest permissible time for reciting the morning shema is earlier in Shulḥan ‘arukh ha-rav than it is in the Siddur.

94 Tchernowitz, Toledot ha-posekim, 3:265. Lavot opposed the notion of Shneur Zalman revising his opinions, yet it is unclear how he understood the relationship between the texts. Noe responded that it is not disrespectful to suggest that Shneur Zalman revised his positions: the Talmud has many such cases, and it is clear that Shneur Zalman did just that. See also Sat, “Ha-hevdeilim,” 147–50. For a defense of Lavot, see Yehoshua Mondshine, “Sidduro shel rabbeinu ha-zaken: pirkei ‘iyun, birur u-sekirah,” in Oberlander, Ha-siddur, 153–55.

95 E.g., Shulḥan ‘arukh ha-rav, oraḥ ḥayim 318:11; Raskin, Siddur, 243. This is also an example of Shneur Zalman's initial reliance on Magen Avraham and later revision.

96 Maidanchik argued that Noe's reasons can be subsumed under Lavot's explanation. She claimed that both scholars acknowledged that Shneur Zalman's attitude towards Kabbalah as a legal source constitutes the prime difference between his early and later works. “Shinuyim be-fiskei ha-rav mi-L'adi,” 124. Note that from Noe's language it is apparent that he thought he was rejecting, not explicating, Lavot's approach.

109 Regarding commentary, Rabbi Shneur Zalman Mordekhai Schneersohn of Zhitomir (d. 1866) annotated Shneur Zalman's Seder netilat yadayim li-se‘uda and Seder birkat ha-nehenin, and added the title Kuntras shem ha-gedolim. In 1946 Ramash began to prepare the manuscript for publication, adding his own notes. Ramash did not complete the project, but the unfinished work was published in 1999.

Regarding an abridged version, the information on this attempt is sparse. According to Lubavitch tradition, one of the Hasidic masters instructed Moshe Rosenblum (1850–1928) to write such a work. Once the project was completed, a fire broke out in Rosenblum's home on Sabbath. Exercising self-control, Rosenblum did not transgress Sabbath in order to save the manuscript from the flames.

113 Mondshine, Sifrei ha-halakhah, 14n2 (Hebrew numbers). Aharon, son of Rabbi Yissakhar Dov Rokeaḥ of Belz, reported the tradition in his father's name. Mondshine suggested that the account may be referring to a no longer extant version, as opposed to the four extant sections of mahadura tinyana. Cf. Heilprin, Sefer ha-ẓe'eẓa'im, 19n. Heilprin cites an alternative testimony regarding the Belz tradition. For sections of Shulḥan ‘arukh ha-rav that may have been written after the Siddur, see Oberlander, “Sidduro shel admor ha-zaken,” 37; Sat, “Ha-hevdeilim,” 1–2.

In the specific case that precipitated the discussion, the earlier text (608:6) followed Magen Avraham, while the later text (156:7) rejected this position: a further example of Shneur Zalman's initial reliance on Magen Avraham, and later reversal. In addition, the later ruling could be sourced to Zohar: a further example of greater weight given to kabbalistic sources in Shneur Zalman's later writings.
