Yemenite-Israeli rabbi, scholar and translator (1917–2000) From Wikipedia, the free encyclopedia
Yosef Qafiḥ (Hebrew: יוסף קאפחpronounced[josefqafiħ], Arabic: يوسف القافح), widely known as Rabbi Yosef Kapach (27 November 1917 – 21 July 2000), was a Yemenite-Israeli authority on Jewish religious law (halakha), a dayan of the Supreme Rabbinical Court in Israel, and one of the foremost leaders of the Yemenite Jewish community in Israel, where he was sought after by non-Yemenites as well.[1] He is widely known for his editions and translations of the works of Maimonides, Saadia Gaon, and other early rabbinic authorities (Rishonim), particularly his restoration of the Mishneh Torah from old Yemenite manuscripts and his accompanying commentary culled from close to 300 additional commentators[2] and with original insights. He was the grandson of Rabbi Yiḥyah Qafiḥ, a prominent Yemenite leader and founder of the Dor Deah movement in Yemen. Qafih was the recipient of many awards, as well as an Honorary Doctorate from Bar-Ilan University.
Yosef Qafiḥ was born 27 November 1917 in Sana'a in Yemen. His father was Rabbi David Qafiḥ, who died after being assaulted by an Arab man, when his son Yosef was less than one year old. At the age of five, Yosef also lost his mother and was raised by his grandfather Rabbi Yiḥyah Qafiḥ, under whom he studied Torah. In 1927, Yosef helped his grandfather retrieve the oldest complete Mishnah commentary from the Jewish community's genizah in Sana'a, containing Rabbi Nathan ben Abraham's elucidation of difficult words and passages in the Mishnah.[3] The commentary was later published in Israel. (Young children in Yemen were often employed as copyists of ancient manuscripts.) At the age of thirteen, Yosef wrote out a complete copy of Maimonides' Guide for the Perplexed in Judeo-Arabic.[4]
When Yosef was 14, his grandfather died. When he and two of his acquaintances went to visit the burial-site of Yosef's grandfather, and then his father, they were accused of having burnt the grave of his grandfather's chief disputant, and were arrested and held in bonds. Because of the rift in the community between those who adhered to kabbalah and the rationalists, the two informers told the Arab authority about the young Yosef being a Jewish orphan, and that under the laws of the state's Orphans' Decree he was required to be taken under the arms of the Islamic State and converted to Islam. The child was questioned about his father and upon the realization that his forced conversion to Islam was the informants' intent–with the arson accusation being a means to render him vulnerable to Muslim authority and attention–he did not answer his interrogator, and was released by the prison authority for no explained reason.[5] The Imam, Yahya Muhammad Hamid ed-Din, urgently requested that they find him a bride to bypass forced conversion to Islam as an orphaned child. Rabbi Yihye al-Abyadh (the king's physician) arranged for Yosef's marriage to Bracha Saleh (Tzadok) in the same year of his grandfather's passing. In his early years, he worked as a silversmith.
Rabbi Yosef Qafiḥ was a member of the Chief Rabbinate Council of Israel and president of the Yemenite community in Jerusalem. He died on 21 July 2000 at the age of 82, and is buried in Jerusalem's Har HaMenuchot cemetery.
His main work in the field of Torah literature was his translation and publication of manuscripts of numerous works by SephardicRishonim, including HaNivchar BeEmunot u'va-Deot of Saadia Gaon, the Torat Chovot HaLevavot by Bahya ibn Pakuda, the Kuzari by Judah ha-Levi and many other works in Judaeo-Arabic. The prime place in his oeuvre is reserved for the writings of Maimonides: he translated the Guide for the Perplexed, Commentary on the Mishnah, Sefer Hamitzvot, letters and Beiur M'lekhet HaHiggayon and edited a 24-volume set of the Mishneh Torah (posthumously divided into 25). His works and translations received recognition from the academic and Rabbinic world alike. His edition of Maimonides' Commentary on the Mishnah in particular is a regularly cited source in ArtScroll's Yad Avraham Mishnah Series, with Rabbis Nosson Scherman and Meir Zlotowitz recognizing it as a "justly acclaimed translation of what is assumed to be Rambam's own manuscript."[9] Rabbi Ovadia Yosef wrote that the seven years he sat with "the great Gaon Rabbi Yosef Qafiḥ ZT"L" in the beth din were "seven good years"[10] and that Rabbi Qafiḥ toiled over his Torah day and night.[11]
Qafih wrote extensively about the heritage of Yemenite Jews, describing in a book, “Halichot Teman”, the Jewish life in Yemen, eclipsing even the renowned works of Amram Qorah and ethnographer, Yaakov Sapir. He published several works of Yemenite Jewish provenance, such as Meor ha-Afelah by Nethanel ben Isaiah (14th-century), and Garden of the Intellects by Natan'el al-Fayyumi (12th-century). He also published a book under the title of “Shivat Tzion” Tiklal, a Yemenite prayer book reflecting the views of Maimonides in three volumes. In 1993 he published a new version under the title of “Siaḥ Yerushalayim” in four volumes (posthumously edited to six). Qafiḥ's seminal work, however, was his commentary on Maimonides' Mishne Torah, where he highlighted textual variations based on the Yemenite handwritten manuscripts of Maimonides' Code of Jewish law. Qafiḥ identified with the Dor Dai tendency, except that he did not publicly express opposition to the Zohar beyond saying that it was preferable to draw sustenance from the teachings of Maimonides. In his leadership of the Yemenite community in Israel he endeavored to maintain peace between the main factions in the community and worked to preserve Yemenite customs. In matters pertaining to Yemenite customs, even where later customs conflict with the earlier custom, Rabbi Mordechai Eliyahu regarded the opinion of Rabbi Qafiḥ, who he called Mori Yusef (Hebrew: מארי יוסף),[12] to be decisive.[13]
The fruit of Rabbi Qafiḥ's scholarship remains, for the most part, untranslated and as such largely inaccessible to the English-speaking public. Examples of English translations based on his bilingual (Hebrew/Arabic) editions include Saadia on Job by Dr. Lenn E. Goodman,[14] Professor of Philosophy and Jewish Studies, and Maimonides' Sefer Hamitzvot[15] by Rabbi Berel Bell, Dayan of Kehilas Lubavitch on the Beth Din of Montreal and the founding dean of Chaya Mushka Seminary.
Rabbi Qafih's followers observe halakhah as codified in Maimonides' Mishneh Torah with Qafih's commentary. Halakhic literature stemming from the rulings of Maimonides and Qafih has been published, often as essays. Although Rabbi Qafih had serious reservations about learning halakhah from halakhic compendiums and abridgments,[16] for the benefit of the general public his students have published books to aid in following the rulings of Maimonides and Qafih. Among these works, the following has been published:
ברכת משה על הלכות ברכות by Rabbi Aviad Ashwal,[17] on the laws of b'rakhoth;
מועדי משה: הלכות חנוכה by Rabbi Aviad Ashwal, on the laws of Chanukkah;
שמטת משה על הלכות שביעית by Rabbi Aviad Ashwal,[16] on the laws of Shmitta.
Of note is an index volume of sorts, Lanhotam (Hebrew title: לַנְחֹתָם דרך 'משנה תורה'), by Yosi Seri[19] which is a reference guide for learners of the Mishneh Torah with Rabbi Qafih's commentary.
Written responsa of Rabbi Qafih have been printed (listed below in Published Works) and continue to be publicized on a monthly basis in Allon Or Hahalichot.[20] Responsa drawn from Rabbi Qafih in oral conversations have been put to writing in תשובות הרב יוסף קאפח לתלמידו תמיר רצון (edited by Rabbi Itamar Cohen)[21] and שו"ת טל יוסף: הרב יוסף קאפח of Rabbi Shmuel Tal.[22]
Alongside the written works, shiurim rooted in Maimonidean doctrine and the exposition of Rabbi Qafih's teachings are given on a regular basis by a number of Rabbis in Israel such as Rabbis Ratzon Arusi, Uri Melammed,[23] and Elyaqim Tzadoq. Shiurim of Rabbi Ratzon Arusi, Qafih's foremost student, are made freely available at net-sah.org.
Close to 10 volumes of the Masorah L'Yosef journal have been published which include essays by authors of various persuasions that deal with Maimonides' and Rabbi Yosef Qafih's teachings. Other publications of note, with essays relating to Qafih's teachings, include ספר זכרון לרב יוסף בן דוד קאפח,[24]From Yemen to Israel (Hebrew: מתימן לישראל),[25] and דברי שלום ואמת.[26]
Of special note among Rabbi Yosef Qafih's expounders is Rabbi Aharon Qafih who in addition to giving many weekly shiurim[27][28] has published, among numerous essays,[29] the books יריעות אהרן[30] and מנחת אהרן[31] devoted to Maimonidean doctrine and the teachings of Rabbi Yosef Qafih.

Translations into Hebrew of Saadya Gaon's Arabic translation and commentary on Tanakh have included volumes on the Torah,[33] Megillot,[34] Tehillim,[35] Iyyov[36] (translated to English by Dr. L. E. Goodman),[14] Mishlei,[37] and Daniel.[38][39] (Although, on its own,[40] Saadia on Isaiah was not translated by Kafih, he sometimes translated portions that he quoted,[36] while at other times he referred[36] readers to Derenbourg's edition.[41][42][43])

Sefer Hamitzvot, in original Arabic with facing Hebrew translation (5731 [1971]).[82] This edition succeeded the Rambam L'Am edition of Sefer HaMitzvot (5718 [1958]) for which Rabbi Qafih provided his translation and notes. In his later edition Rabbi Qafih repeatedly called out the former edition for its printing of errors against his agreement and without his knowledge,[83] emphasizing that it should not be relied upon.[84]
Based on what was then the newly-published edition of Rambam L'Am,[85] Rabbi Dr. Charles B. Chavel translated Sefer HaMitzvot, published in two volumes by the Soncino Press in 1967 as The Commandments (Sefer Ha-Mitzvoth of Maimonides). Soncino Press described their edition as "the first complete English translation of the Sefer Ha-Mitzvoth based upon Rabbi Kapach's work." As Rabbi Bell would later note, "neither Rabbi Chavel nor Soncino were aware of Rabbi Kapach's reservations about the 1958 edition,"[86] as only 13 years thereafter, in 1971, would Rabbi Qafih supersede this Mossad Harav Kook edition.
Based on Rabbi Qafih's edition with the original Arabic, Rabbi Berel Bell produced an English translation (from Qafih's Hebrew)[87] of the mitzvot in two volumes.[88] His English translation, however, lacks Maimonides' Introduction and Principles.

Rabbi Yosef Qafih, recalling the event, describes it as follows: "There is a custom had among most of the people who assume oversight over the synagogues in Yemen that any book that has become worn-out or become very old they'd store it away in the vault situated beneath the hekhal (Ark) and this is its genizah. From time to time, when a sufficient quantity of books, fragments of books, pages and worn-out leaves [of books] has been amassed there, they collect them, place them inside earthenware jars and bury them in the cemetery, near one of the righteous men, and occasionally there are buried books, pages and leaves of valuable worth, which the same person who is meant to oversee [the affairs of the synagogue] has not fully appreciated their worth. To our happiness, many times the grave diggers are too lazy to dig deep, well beneath the earth. Wherefore, occasionally, after the rainy season, especially in the years that are blessed with plenty of rain, the heads of these jars are exposed because of rain erosion, where it eroded and made thin the upper layer of earth. My grandfather who is now deceased, the Rabbi Yihya Qafih, of blessed memory, would complain about the overseers of the synagogues and reprimand them over burying in the genizah things which contain pearls of great beneficial use, and of invaluable worth, without allowing for a man who is more adept [than he] and who knows how to examine them first and to determine what is worthy of being buried and what is still worthy of being used by the coming generations, so as to give some merit to the congregation. He commanded one of the caretakers of the cemetery that, in the event that the heads of the jars such as these should ever be exposed, he was to inform him, before he proceeded to dig deeper in order to bury them once more. I remember when I was about ten years old, the man came to inform my grandfather, of blessed memory, that such [a jar] that had been buried was now exposed. I remember that it was on a Thursday, before nightfall. On the next day, on Friday morning, my grandfather took me with him, and we went out together to the place of the genizah, according to where the informant had directed us. Now since my grandfather, of blessed memory, was already old, above eighty years in age, and it was difficult for him to bend down, I was the one who took out books and fragments of books, and ordinary pages that were wet and moldy, dusty and muddy, both hand-written manuscripts and printed texts; my grandfather, of blessed memory, sitting throughout all this time upon a stone, examining them and sorting them, one by one, until the early afternoon, and then we returned the rest inside the jar and covered it up. We took with us what we had sorted and returned to the city. At the departing of the Sabbath, my grandfather sat down to sort through his spoils, to take-apart the pages [of books] that had already stuck together because of the wetness from the rains that had penetrated within the jar. In this genizah we found hand-written pages from the Babylonian Talmud, and also fragments from Maimonides' Guide for the Perplexed, from Mishnah commentaries, from the commentaries of Rabbi Saadia Gaon, from the Midrash Hagadol, and many more. Whatsoever our hook brought up on that blessed day is today in my possession. Some of them still show upon them the vestiges of the soil and clay to this very day. Among the spoils, we found an old hand-written book, the majority of whose pages were already sticking together, clumps upon clumps. My grandfather sat a long time, slowly soaking them in water and with great patience, after he had checked and saw to his satisfaction that the letters were not being erased by soaking them in water. I still remember how the pages were strewn across the entire room of my grandfather's workshop, of blessed memory, so that they could dry. After drying and arranging the pages, it was clear that this was the very Mishnah commentary which we now present before our readers. This book was the only surviving sort of its kind in the world, which, had it not been for this action, it would have been lost to the world. The book was missing a few pages, in the Order known as Moed, at the introduction to Tractate Shabbat, it was missing perhaps one page, and in Tractate Pesahim it was again missing perhaps one page, as also in Tractate Yoma it was missing perhaps one page, but the remainder of the book, to our delight, was found altogether complete, from beginning to end" (Six Orders of the Mishnah - Commentaries of the Rishonim, vol. 1, pub. El ha-Meqorot: Jerusalem 1955, s.v. Appendix: Perush Shishah Sidrei Mishnah [Introduction], p. 6).

In a different context Kafih referred to Dr. N. [Naftali Joseph] Derenbourg as having satisfactorily translated and published, from and with the Judeo-Arabic, Maimonides' commentary to Taharot (Kafih edition of the Mishnah with Maimonides' commentary, Seder Zera'im, p. 10).
Fred Rosner published an English translation of Maimonides' entire commentary on Tractate Sanhedrin (published as Maimonides Commentary on the Mishnah: Tractate Sanhedrin [New York, 1981]) for which Rabbi Kafaḥ's Hebrew translation was one of two major source works used, his second major source work being "the annotated Hebrew translation of Gottlieb (Hanover. 1906)" (p. xvi-xvii).
In an earlier translation of his Rosner published Moses Maimonides' Commentary on the Mishnah: Introduction to Seder Zeraim and Commentary on Tractate Berachoth (New York, 1975), but Kapach's translation was not central to this with Al Harizi's Hebrew translation being the major source work used, although Rosner noted that "[c]onsultation with the new Hebrew translation of Kapach was very valuable in many instances" (p. 32-33).
Chavel states "the present English translation, which covers the Negative Commandments also, is based throughout on the new Jerusalem Hebrew text" published by Mossad Harav Kook (Jerusalem, 5718), to whom Chavel states he is "greatly indebted for their permission to make use of their new text" (The Commandments, Volume One, foreword, p. xv).

Responsa of the Rambam ed. Blau (Rubin Mass and Makhon Moshe, Jerusalem, 2014), volume one, Divrei b'rakhah of Rabbi Ratzon Arusi (Hebrew): "ואליבא דאמת, שהתרגום של מהרי"ק למספר תשובות אינו תרגום במלוא מובנה של המילה, כי יש והוא רק תמצית התשובה,"... "כך שתרגומיו של מהרי"ק לאותן תשובות הן קרובות לעיבוד מאשר לתרגום, ובהן השתמש מהרי"ק לצורך פירושו למשנה תורה."... "הנה נצא ונראה כיצד דקדקו חכמי התלמוד בביאור לשון המשנה, תוך השוואה עם ברייתות, אפילו ברייתות שאין בהן מחלוקת על המשנה אלא שינוי לשון, כי אין שני נביאים מתנבאים בסגנון אחד, וכל שכן המתרגמים, ושינויי לשון, יש בהם כדי לסייע ללומדים לעמוד על הכוונה היותר אמתית של המחבר."
