Introduction
Rabbi Joseph ben Abraham HaNassi Hayyun was one of the central figures of Portuguese Jewry in the second half of the 15th century and the last spiritual leader of the Lisbon Jewish community before the expulsion of 1497. He gained renown as the greatest biblical exegete in Portugal and was an influential writer whose impact extended to his generation and beyond.
Biography and Status
Rabbi Joseph Hayyun was born into a wealthy and distinguished family in Portugal. Although many details of his life have not been preserved, it is known that he chose to abandon a life of affluence to devote himself entirely to Torah study and teaching. He played a central role as the spiritual leader of the Lisbon community, which was the largest and most significant Jewish community in Portugal at that time.
As the chief rabbi of Lisbon, Rabbi Joseph Hayyun served as the supreme halakhic authority in the community. Difficult halakhic questions were directed to him, and his responsa were recognized as binding and authoritative. His elevated status was also evident in the fact that Don Isaac Abarbanel, one of the great scholars of the generation, consulted with him on halakhic and biblical questions.
His Exegetical Works and Characteristics
Scope of His Works
Rabbi Joseph Hayyun was a prolific exegete who wrote extensive commentaries on numerous biblical books. Among his known works:
- Commentary on the Book of Psalms – A comprehensive and detailed commentary published in Salonika in 1523
- Commentary on the Book of Jeremiah – An in-depth work completed on the 5th of Tammuz, year 5231 (1471)
- Commentary on the Book of Ezekiel – An extensive commentary divided into two parts
- Commentary on the Book of Hosea – An important work in the exegesis of the prophetic books
- Commentary on the Book of Joel – A commentary preserved in manuscripts
- Millei de-Avot – A commentary on Tractate Avot, published in Constantinople in 1578 and reprinted in Venice in 1606
His Exegetical Method
Scholars have identified several unique characteristics in Rabbi Joseph Hayyun’s exegesis:
A. Extensive Introductions: Most of his works begin with a comprehensive introduction in which he discusses eight to ten general themes characterizing the book under discussion. This approach demonstrates his desire to provide readers with a holistic and systematic view of the subject.
B. Completeness in Commentary: Hayyun regularly copies the entire verse and explains all its parts and recurring expressions. He does not settle for partial explanation but strives for complete coverage of the biblical text.
C. Emphasis on Peshat (Plain Meaning): Most of his commentary is based on the plain meaning of Scripture, applying extensive knowledge of grammar and language. However, he does not refrain from occasionally bringing homiletical and mystical interpretations when appropriate.
D. Multiple Interpretations: His thorough nature led him to provide several interpretations for a single verse, examining various possibilities for understanding the text.
E. Anti-Christian Stance: His commentaries include many anti-Christian motifs, reflecting the Jewish-Christian polemic of his time.
F. Methodological Innovation: Hayyun’s main innovation was that he did not use at all the exegetical principle known as “repetition of content in different words.” Scholar Abraham Gross argued that this is a central motif in his commentary, distinguishing him from many other exegetes.
G. Sensitivity to Reality: His commentaries reflect high sensitivity to matters of order and organization, as well as attention to practical issues of daily life, as evident in his commentary on Jeremiah 35 concerning the Rechabites, where he explains the health benefits of living outside the city.
Theological Significance of His Commentaries
Rabbi Joseph Hayyun participated in central theological debates of his time. In response to a question Don Isaac Abarbanel posed to him regarding the level of creative freedom Moses had in writing the Book of Deuteronomy, Hayyun detailed his position on the relationship between prophecy and Scripture. This question and his answer mark a new chapter in the historical examination of Moses’ role in writing the Torah, as noted by modern scholars.
His Students and Influence
Rabbi Joseph Hayyun was a sought-after teacher who raised a generation of distinguished students who continued his path and developed his legacy. Among his prominent students:
Rabbi Abraham ben Nissim Hayyun
One of Rabbi Joseph Hayyun’s outstanding students who continued his path in study and exegesis. He was the author of the book “Amarot Tehorot” (Pure Sayings) and continued the Hayyun family tradition in Torah teaching and exegesis.
Rabbi Joseph Jabez (1438-1539)
One of the most famous students of Rabbi Joseph Hayyun. Jabez lived for a time in Portugal, where he became close to Rabbi Joseph Hayyun, who greatly influenced him and instilled in him the taste for mysticism that he later displayed in his writings. After the expulsion of the Jews from Spain, Jabez settled in Mantua, Italy, where he met his compatriot, the kabbalist Judah ben Jacob Hayyat, whom he encouraged to write the commentary “Minhat Yehudah” on the kabbalistic work “Ma’arekhet Elahut.”
Jabez was a staunch opponent of philosophy, basing the truth of religion on the miracles recorded in the Hebrew Bible. He criticized the thirteen principles of faith of Maimonides, the six of Hasdai Crescas, and the three of Joseph Albo. According to him, only three fundamental principles are alluded to in the verse “I Am that I Am” in the narrative of the burning bush in the Book of Exodus.
Among his known works: he wrote “Or HaHayyim” and “Hasde Hashem,” and also left numerous manuscript works which, according to Ghirondi, were still (as of 1906) in the possession of the author’s descendants. His son, Rabbi Isaac Jabez, continued his path.
Rabbi David ibn Yahia
Another important student who authored the books “Kav VeNaki,” “Kehilot Moshe,” and others. He continued the tradition of study and exegesis he received from his teacher.
Don Isaac Abarbanel
Although there is no complete agreement among scholars whether Abarbanel was formally Rabbi Joseph Hayyun’s student, the relationship between them was close and significant. Abarbanel consulted with Hayyun on halakhic and biblical questions and even wrote, following a question he posed to him, the work “Maggid Mishneh.” This work deals with profound issues regarding the prophetic status of the Book of Deuteronomy and Moses’ role in writing it.
Rabbi Moses Hayyun
The son of Rabbi Joseph, who served after him as the last rabbi of Lisbon. He continued his father’s path in leading the community until the expulsion.
Rabbi Judah Albotini
According to several scholars, Rabbi Judah ben Moses Albotini, who was the son of Rabbi Joseph Hayyun’s daughter, is also considered his student. He was a prominent head of yeshiva and kabbalist, author of “Yesod Mishneh Torah” and other works.
Rabbi Abraham Hayyun
Great-grandson of Rabbi Joseph Hayyun, who was the publisher of his work “Millei de-Avot.”
Exile and Final Days
When the decree of expulsion from Portugal was issued in 1496, Rabbi Joseph Hayyun left Lisbon and wandered to Constantinople, where many of the Jewish refugees from Portugal settled. There, in the city that became an important Torah center for Sephardic Jewry, Rabbi Joseph continued his Torah work.
Rabbi Joseph Hayyun passed away in Constantinople shortly after arriving there, in 1497. However, his spiritual legacy continued to live through his students, especially Rabbi Joseph Jabez, and through his writings which continued to be copied, studied, and disseminated among Sephardic Jewry in exile.
His Continuing Influence
Rabbi Joseph Hayyun’s commentaries continued to influence generations of scholars. His writings were printed in various editions over the centuries, and to this day they are considered important sources for research in biblical exegesis of Sephardic Jewry. In recent years, renewed interest in his work has emerged, and scholars have published critical editions of his commentaries on various books.
Numerous academic studies have been dedicated to researching Rabbi Joseph Hayyun’s exegetical method. Among these are the pioneering work of scholar Abraham Gross, “Rabbi Joseph ben Abraham Hayyun: Leader of the Lisbon Community and His Literary Work” (Bar-Ilan University, 1993), as well as research by Joseph Elitzur, Yohanan Kapach, Amos Frisch, and others.
Summary
Rabbi Joseph ben Abraham HaNassi Hayyun was a central figure in 15th-century Portuguese Jewry. As leader of the Lisbon community, he served as the supreme halakhic authority and spiritual guide for the community. As a biblical exegete, he developed a unique approach combining emphasis on the plain meaning with depth of analysis and sensitivity to theological questions.
His students, primarily Rabbi Joseph Jabez, continued his path and spread his teachings in the Sephardic communities in exile. His exegetical works, much of which has been preserved and published in various editions, constitute a significant contribution to the treasury of Jewish exegesis and attest to his greatness as one of the greatest biblical exegetes in Portugal and in general.
