Rabbi Chaim Kanievsky

Expert Report: The Work and Torah Teaching of Maran Rabbi Shemaryahu Yosef Chaim Kanievsky, of Blessed Memory

Part A: The Background and Torah Foundation of Leadership

Chapter I: Lineage, Biography and the Shaping of the Figure of the "Sar HaTorah"

2.1. Roots and Lineage at the Lithuanian Torah Centre

Rabbi Shemaryahu Yosef Chaim Kanievsky, called "Reb Chaim" and "Maran Sar HaTorah" in the Haredi sector, was born on 15 Tevet 5688 (1928) in Pinsk, Poland.^[1] His standing as a prominent spiritual leader of the Haredi-Lithuanian community stemmed not only from his personal greatness in Torah but also from his central lineage. He was the eldest son of two pillars of Lithuanian Jewry as it was renewed in the Land of Israel: Rabbi Yaakov Yisrael Kanievsky, known by his byname "the Steipler" (author of the book "Kehillot Yaakov"), and Mrs. Pesha Miriam, who was the sister of the "Chazon Ish" (Rabbi Avraham Yeshaya Karelitz).^[1] This double lineage gave him generational legitimacy as a direct descendant of the spiritual and halakhic architects of the Lithuanian community in Bnei Brak. At his circumcision he was given the name Shemaryahu Yosef Chaim, after his two grandfathers: Rabbi Shemaryahu Yosef Karelitz (rabbi of Kosova) and Rabbi Chaim Peretz Kanievsky.^[1]

A scholarly understanding of his standing must include the combination of authority created by his marriage on 7 Kislev 5712 (December 1951) to Mrs. Bat Sheva Esther.^{[1, 2]} She was the daughter of Rabbi Yosef Shalom Elyashiv, of blessed memory, who was already at that time a dominant halakhic figure in Jerusalem.^[1] This family union created a unique axis of Torah authority that joined the school of the established study halls of Bnei Brak (the Chazon Ish and the Steipler) with the school of halakhic ruling and rabbinic adjudication of Jerusalem (Rabbi Elyashiv). Thus Rabbi Kanievsky found himself at the centre of the Lithuanian leadership system while still young, receiving an intellectual and dynastic mandate to lead.

2.2. His Course of Study and Complete Devotion to Torah

The Kanievsky family immigrated to the Land of Israel on 1 Nisan 5694 (1934) and settled in Bnei Brak.^[1] As a child, Rabbi Kanievsky studied at "Talmud Torah Rabbi Akiva – Merkaz" and devoted much time to studying with his father, the Steipler, with whom he studied most of the tractates of the Talmud (Shas).^[1] At the age of 10 he entered the "Tiferet Zion" yeshiva in Bnei Brak, and after six years of study moved to "Beit Yosef" and finally to the Lomza Yeshiva in Petah Tikva.^[1] This course, which combined in-depth personal study under the guidance of his father and of his uncle the Chazon Ish (whom he would meet every week before the Sabbath) ^[2] with formal study in the central yeshivas, shaped his comprehensive method. At the age of 17, during his first year at the Lomza Yeshiva, he had already completed the entire Talmud.^[1]

The figure of Rabbi Kanievsky was woven around a narrative of complete devotion to Torah, which reached its peak during the War of Independence. When the war broke out, the students of the Lomza Yeshiva were mobilized to stand guard on the Egyptian front, equipped only with sticks and stones. The commander, Rabbi Shmuel Grossbard, instructed the young student Chaim Kanievsky to go up to the top of the hill and study there with his Gemara instead of taking part in the guard duty, until the fighting ended.^[2] This story became a cornerstone of the Haredi public narrative, representing the ideal of torato umanuto (Torah as one's sole occupation). Its meaning is that not only was Rabbi Kanievsky an immensely learned scholar, but his strength stemmed directly from the supremacy of Torah study as a spiritual protective force for the community, which lent deep legitimacy to his standing.

2.3. The Kollel Years and the Proclamation "Mara de-Khula Talmuda"

After their marriage, the Kanievsky couple lived at first in Petah Tikva, where Rabbi Kanievsky continued to study at the Lomza Yeshiva.^{[1, 2]} They then moved to Bnei Brak and lived at first in an apartment shared with the families of other rabbis, before moving to a more spacious apartment.^[2] In Bnei Brak Rabbi Kanievsky began to study at the "Ateret Yosef" kollel, later known as the Chazon Ish Kollel, where he devoted decades of continuous study.^{[1, 2]}

His Torah standing was recognized officially already at his wedding, when the Chazon Ish praised the groom and crowned him with the title "Mara de-Khula Talmuda" (master of the entire Talmud).^[2] This title emphasized that his leadership would be founded on his extraordinary mastery of every part of the Torah. His choice to remain a kollel scholar devoting all his time to study, rather than to fill an official post as head of a great yeshiva, reflected his image as one whose greatness stemmed solely from his pure Torah work. After the death of his father, the Steipler, in 5745 (1985), Rabbi Shach, the leader of the generation at the time, confirmed his standing when he said that the father had "left a son like himself."^[2] These declarations established his public standing as the greatest halakhic authority of the next generation.

Part B: The Doctrine of Study – Principles of Mastery, Methodology and Halakhic Ruling

Chapter II: The Foundations of the Method of Study – Torah Encyclopedism as a Method

3.1. Broad Mastery as a Research Tool

Rabbi Kanievsky earned the title "Sar HaTorah" because of his complete and comprehensive command of the entire Torah literature.^[1] His Torah method does not focus only on a deep understanding of selected topics, but on encyclopedic mastery encompassing every layer of the Oral Torah and of Torah literature. Special importance attached to his command of the literature of the Sages, including minor midrashim that others tend not to engage with.^[1]

His way of study was essentially an all-embracing synthesis: his method of research was based on comparing diverse sources and explaining them in light of one another.^[1] Rabbi Kanievsky used the vast scope of this knowledge as a methodological tool to resolve contradictions, to understand hidden connections and to ground halakhic rulings comprehensively. This approach, which emphasizes comprehensive and summarizing knowledge over intensive analysis of small textual units (as was customary in other yeshiva schools), positioned him as an encyclopedic genius who knew how to derive practical halakha from a vast database.

3.2. The Mishnah and the Yerushalmi at the Centre of Study

In Rabbi Kanievsky's teaching one can identify a marked emphasis on the study of the foundational orders of the Oral Torah, and especially the Mishnah and the Jerusalem Talmud. This focus is not accidental; it reflects his holistic conception of Torah study. He composed the book "Sha'arei Emunah," which contains explanations and novel insights on the mishnayot of the Order of Zera'im ^[3], as well as a work of his own on the Jerusalem Talmud, edited on the basis of his lessons.^[3]

The fact that the eulogies for him emphasized the need to "always run to the Mishnah more than to the Talmud" ^[4] points to the conceptual link between his approach and the importance of the Mishnah as a foundation. The emphasis on the Yerushalmi, which is the Talmud of the Land of Israel, complements the focus on the Order of Zera'im, which deals with the commandments dependent on the Land.^[3] This approach makes it possible to resolve new halakhic questions arising from the settlement of the Land of Israel, and strengthens the idea of the completeness of the Torah and its preparation for the redemption.

3.3. His Ways of Halakhic Ruling: Continuer of the Lithuanian Legacy

In his halakhic rulings Rabbi Kanievsky directly reflected the legacy of his father's house and of his uncle. He continued the "legacy of the laws and instructions" of Rabbi Yaakov Yisrael Kanievsky (the Steipler) and Rabbi Avraham Yeshaya Karelitz (the Chazon Ish).^[5] Within this framework, he adopted the halakhic rules laid down by the Chazon Ish on the subject of the commandments dependent on the Land, such as measures and boundaries.

The format in which he chose to present his rulings was didactic and practical. His central book, "Derech Emunah," was written in the format of the "Mishnah Berurah" of Rabbi Yisrael Meir HaKohen, while dealing with the Book of Zera'im in Maimonides' (Rambam's) Mishneh Torah.^[3] This choice of the Mishnah Berurah format expresses an aspiration to make settled halakha, grounded in study, sources and halakhic deliberation, practically accessible to the general public.^[3] He turned academic topics, which are not in common daily use, into practical halakha, thereby filling the void left by the lack of orderly engagement with these laws in the yeshiva world.

Part C: The Comprehensive Literary Enterprise – Completeness and Precision

Chapter III: Analysis of the Halakhic Enterprise on Maimonides' "Mishneh Torah"

Rabbi Kanievsky was known as the author of many books in a variety of Torah disciplines.^[1] The main thrust of his literary enterprise focused on filling the halakhic gaps remaining in established halakhic ruling, and in particular in connection with the monumental work of Maimonides, the "Mishneh Torah."

4.1. "Derech Emunah" – The Great Supplement on the Book of Zera'im

His book "Derech Emunah" is apparently the most important and best known of his comprehensive works.^[3] It is his great book, which explains the Book of Zera'im in Maimonides. It was written in a format whose aim is to make Maimonides' laws accessible as settled halakha, similar to the way in which the Mishnah Berurah explained the Shulchan Arukh, Orach Chaim.^[3]

The Book of Zera'im deals mainly with the commandments dependent on the Land – terumot, tithes, the Sabbatical year and more. These topics, which were less relevant in the period of exile, returned to the centre of halakhic discussion with the establishment of the Jewish settlement in the Land of Israel. This work provided an established and practical halakhic code, based on the tradition of the Chazon Ish, for the Haredi public facing questions of agriculture and the observance of these commandments in the modern state. Its aim was to fill a fundamental literary gap and to provide a halakhic anchor in these subjects.

4.2. Supplements on Kodashim and Hidden Laws

Rabbi Kanievsky's literary enterprise went on filling gaps in every part of Maimonides, including subjects that do not apply at all in the present time. He composed "Derech Chochmah" on the laws of Kodashim (sacred offerings) in the Mishneh Torah, and "Shekel HaKodesh," a commentary on the laws of Shekalim and of the Sanctification of the New Month in Maimonides.^[3]

A central part of his method is the "doctrine of completeness" – the conception that Torah study is an end in itself, and that all its parts must be studied and explained, including those that have no everyday relevance today. This position is highlighted in the composition of booklets dealing with topics that do not apply in practice: "Nachal Eitan" on the laws of the eglah arufah (the heifer whose neck is broken; a booklet he composed already in his youth), "Emet VeTzedek" on Tractate Gerim, "Metzaref UMetaher" on Tractate Kutim, and "Kinyan HaGuf VeKinyan Peirot" on Tractate Avadim.^[3] The comprehensive engagement with these laws strengthens the conception of the Torah world as a complete and full system. Rabbi Kanievsky also composed introductory works to Maimonides, such as "Kiryat Melech" (source references) and "BeSha'ar HaMelech" (on Maimonides' introduction to the Mishneh Torah).^[3]

Chapter IV: Works Beyond Settled Halakha – Bible, Mussar and the Esoteric

5.1. Commentary on the Bible (Ta'ama DeKra, Limchaseh Atik)

Rabbi Kanievsky did not restrict his writing to the fields of settled halakha and the Talmud. He composed novel insights on the Bible entitled "Ta'ama DeKra," and "Limchaseh Atik," which locates and explains places in the Bible where the verse is obscure and the Sages interpreted its meaning.^[3] These works reflect an exegetical method in which the plain meaning of the verses must be explained solely through the traditional interpretive tools of the Sages (midrash and aggadah). Rabbi Kanievsky used his vast mastery of the literature of the Sages ^[1] to show how the true plain meaning accords with the midrashic interpretation.

5.2. Engagement with Esoteric Literature

Within his conception of the completeness of the Torah, Rabbi Kanievsky also addressed the esoteric layer. He composed "Bahir BaShechakim," which comprises two volumes: Volume 1 is a commentary on the Sefer HaBahir (one of the foundational books of Kabbalah), and Volume 2 contains glosses on further foundational esoteric books such as Sefer Raziel HaMalach, Sefer Noach and Sefer Chanokh.^[3]

This engagement with early kabbalistic literature, such as the Sefer HaBahir, is exceptional among modern mainstream Lithuanian halakhic authorities. This move enhanced his standing as "Sar HaTorah" in a broader sense, as one who knows all the layers and secrets of the Torah. His expertise went beyond the realm of the revealed (nigleh) and entered the realm of the hidden, creating a link between the halakhic system and its spiritual sources.

5.3. Moral Guidance and the Collections of Responsa

Alongside his halakhic work, Rabbi Kanievsky also engaged in imparting the foundations of ethics and conduct. His book "Orchot Yosher" contains teachings on ethics and character traits, gathered mainly from the words of the Sages, the Rishonim and the Acharonim.^[3] It is a tool for personal and communal spiritual guidance.

As his circles of influence widened, books began to be assembled of topical responses that Rabbi Kanievsky had given in writing. These responses, numbering in the thousands, were collected and arranged by Torah scholars and compiled in series such as "Da'at Noteh" and "Derech Sicha."^[3] These collections are essential for understanding how Rabbi Kanievsky's complex method was applied to halakhic situations in real time. The responsa literature provides an indispensable interface for understanding his topical and individual rulings, and illustrates the methodology in specific decisions.

Below is a summary of his Torah oeuvre, illustrating the range of fields in which he engaged:

• Classification of Rabbi Chaim Kanievsky's Books by Field
• Part D: Spiritual and Socio-Halakhic Leadership
• Chapter V: His Work as Leader of the Generation – From Personal Greatness to Public Influence

6.1. The "Sar HaTorah" Model of Leadership in the Lithuanian System

Rabbi Kanievsky served as one of the most prominent spiritual leaders of the Haredi-Lithuanian community in Israel and the Diaspora.^[1] Nevertheless, he adopted a unique model of leadership: a leadership that involves neither direct institutional management nor routine political intervention. It was written of him that he bore "the burden of myriads of the children of the Diaspora and the children of the Holy Land on his shoulders," yet at the same time "he did not wish to intervene in all that took place in the leadership."^[5]

This model of "passive spiritual activism" created a kind of authority free of political interests. His authority stemmed solely from his unchallenged greatness in Torah – the title "Sar HaTorah."^[1] This standing enabled him to influence the central political, social and public decisions through purely Torah rulings, without needing to hold official positions. He was the supreme spiritual figure to whom heads of yeshivas, political leaders and the broad public turned for a decision, thanks to his power in Torah and halakha, which was "a wonder and a marvel."^[5]

6.2. Leadership in Times of Crisis and the Use of the Power of Prayer

Rabbi Kanievsky became famous among the general public as early as the Gulf War (1991), when he said in the name of the Chazon Ish that missiles would not fall on Bnei Brak.^[1] The fulfilment of this statement, which was proclaimed as the realization of a spiritual blessing, gave Rabbi Kanievsky the status of a spiritual protector with special powers, a status vital for mass leadership.

The Rabbi repeatedly stressed the direct link between the spiritual state of the community and its practical success, using the power of prayer as a means of intervening in reality. For example, following concern over the spiritual state of the observant community in Jerusalem, he multiplied prayers and the recitation of Psalms concerning the results of the municipal elections in the city. For this purpose he even travelled specially to pray at the Western Wall on the day before the elections.^[5] These actions illustrate that his leadership, though entirely spiritual, was highly active when he feared that the spiritual and social balance was in danger. His influence on practical outcomes, as happened in the Jerusalem elections, lent dramatic weight to his spiritual decisions.

6.3. Ties with Various Circles and Engagement with Redemption

Although he was a quintessential leader of the Lithuanian stream, Rabbi Kanievsky maintained ties with various circles, and in particular with Chabad Hasidim. The report notes his ties with the leaders (Rebbes) of Chabad and with Chabad Hasidim in general, and his engagement with "anticipation of the Messiah."^[1] His respectful and warm attitude to Chabad was exceptional in the Lithuanian establishment landscape, which is sometimes characterized by reserve.

This demonstrates his broad conception of Torah, which does not confine its leadership to a specific faction. The focus on anticipation of redemption and on the commandments connected with the Land of Israel (through his books on Zera'im ^[3]) reinforces his conception of the comprehensive responsibility of the whole of Israel and of the need to prepare the spiritual ground for the coming of the redemption.

Part E: Perpetuating the Legacy and Continuity (Legacy and Continuity)

Chapter VI: The Next Generation, the Editing of His Torah and the Preservation of His Method

7.1. Creating Infrastructure for Processing and Perpetuating the Literary Enterprise

Although Rabbi Kanievsky was a prolific author, a considerable part of his Torah came in the form of written replies to questioners or brief notes, like the tradition of the great Torah sages of Israel in the 21st century. In order to preserve his Torah and make it accessible, an institutional mechanism of editing and publishing was required. His sons and sons-in-law played a decisive role in turning the treasures of his Torah, which by force of his genius were sometimes less orderly, into usable halakhic codes.

His son, Rabbi Yitzchak Shaul Kanievsky, studied together with his father, wrote some of his letters to the public, and heads the publication of the book series "Da'at Noteh," which presents Rabbi Kanievsky's halakhic rulings with sources and explanations.^[3] After the death of Rabbanit Bat Sheva in 2012, Rabbi Yitzchak Shaul moved into his father's home in order to assist him.^[3] His son Rabbi Avraham Yeshaya helped edit his books and edited the book "Karyana DeIgarta."^[3] This pattern, in which the descendants serve as "intellectual publishers," is an innovative pattern that ensures the preservation and processing of the halakhic legacy in a form accessible to future generations.

7.2. Leading Torah Institutions in His Path

Rabbi Kanievsky's descendants continue his path in leading central Torah institutions, which ensures that the method of study based on broad mastery and the completion of entire orders will be preserved and passed on. His son, Rabbi Shlomo Kanievsky, serves as head of the "Tiferet Zion" and "Kiryat Melech" yeshivas in Bnei Brak. The "Tiferet Zion" yeshiva is the institution in which Rabbi Kanievsky studied in his youth.^{[1, 3]} His son-in-law, Rabbi Zelig Braverman, is head of the "Derech Emunah" and "Netivot Yitzchak" yeshivas, and he also edited Rabbi Kanievsky's commentary on the Yerushalmi.^[3] The establishment of yeshivas whose names are directly linked to his works ("Derech Emunah") or to institutions that were milestones in his life ensures that the scholarly legacy will be passed on.

Below is an analysis of the next generation and its role in preserving Rabbi Kanievsky's teaching:

• The Array of Descendants and Their Role in Preserving Rabbi Kanievsky's Teaching
• Part F: Conclusions: Rabbi Kanievsky's Place in Modern Torah History
• Chapter VII: Concluding Assessment and Comparative Discussion

8.1. Summary of the Torah Teaching and the Place of the Halakhic Authority

Rabbi Shemaryahu Yosef Chaim Kanievsky, who passed away on 15 Adar II 5782 (2022) ^[1], embodied in a distinctive way the Lithuanian ideal of leadership based solely on greatness in Torah. His Torah method was characterized by unprecedented encyclopedic mastery ^[1], which served as a tool for synthesis and halakhic ruling. He did not content himself with the role of an everyday halakhic decisor, but acted as a mighty initiator of Torah projects, working to complete missing halakhic codes, with an emphasis on books that do not apply in the present time (Zera'im, Kodashim, eglah arufah).^[3] This enterprise was intended to ensure the completeness of study and the practical preparation for the renewal of every part of the Torah.

His focus on the laws of the Land of Israel (through "Derech Emunah" on the Book of Zera'im) and his in-depth study of the Yerushalmi underscored his commitment to the vision of a complete Torah leadership in the Holy Land. The scope of his work, extending from settled halakha and midrash to early esoteric literature (such as the Sefer HaBahir) ^[3], established his standing as one who commands every layer of the Torah.

8.2. Comparison with the Previous Generation and Sociological Influence

Rabbi Kanievsky can be placed in a unique context among the great figures of his generation. Unlike his father-in-law, Rabbi Yosef Shalom Elyashiv, who focused on detailed and precise halakhic ruling and on solving difficult problems in the rabbinic courts (divorces, agunot), or Rabbi Elazar Menachem Shach, who focused on leading the yeshiva world and on public political direction, Rabbi Kanievsky combined the depth of uncompromising scholarly mastery with a direct connection to the masses. He succeeded in maintaining the image of a pure "matmid" (unceasing student), detached from public wheeling and dealing, yet one who by the power of his Torah decided crucial public issues.^[5]

His standing as "Sar HaTorah" enabled him to lead the Lithuanian community without holding an official post, creating a charismatic model of leadership that was recognized also on the basis of manifest spiritual successes (such as the matter of the missiles in the Gulf War).^[1] The power of his leadership stemmed from the perfect integration of Torah genius and total devotion.

8.3. His Death and His Legacy for Future Generations

Rabbi Kanievsky's death in 2022 marked the end of an era of halakhic authorities who directly carried the authority of the Torah "transmission" from the founding generation of the Lithuanian centre in the Land of Israel (the Chazon Ish and the Steipler).^[1] His greatness and the scope of his work symbolize the peak of the Lithuanian methodology based on encyclopedic mastery.

His legacy now obliges the next generation not only to study his Torah, but to preserve and apply the comprehensive halakhic projects he left behind, by adding modern halakhic codes based on his writings, as has already been done in the "Da'at Noteh" and "Derech Sicha" series.^[3] Thus Rabbi Kanievsky remains a formative figure whose literary and halakhic legacy will influence Haredi-Lithuanian halakhic ruling for decades to come.
