Dunash ben Labrat

Biographical Background and the Cultural-Geographical Context of the Cordoba School

Rabbi Dunash HaLevi ben Labrat, known in Hebrew and exegetical sources also by the name "Adonim HaLevi" or "Adoniyah," represents one of the most revolutionary and influential figures at the beginning of the Golden Age of Spanish Jewry in the tenth century.^[1] The name "Dunash," which was common among Jews in North Africa and the Iberian Peninsula under Islamic rule, has been linked in etymological research to the Spanish honorific "Don," meaning lord, a hypothesis supported by the fact that in many Hebrew sources his name was translated directly as "Adonim" or "Adoniyah."^[1] Other scholars suggest that the name is of Berber origin.^[1] Dunash was born and educated in the city of Fez, Morocco, around 920, which was at that time a vibrant spiritual and cultural center.^[1] In his youth he traveled to the center of Torah and knowledge in Babylonia, where he studied in the yeshiva of Rav Saadia Gaon (Rasag), and there are even traditions suggesting that he was the Gaon's grandson.^[1] The period of his studies in Babylonia shaped his linguistic and philological worldview; there he was exposed to the scientific methods of analysis of Arabic and Hebrew, began to compose poems that gained him a name and reputation, and acquired the foundations of his innovative grammatical method.^[1]

The central turning point in Dunash's life and activity occurred when Rabbi Hasdai ibn Shaprut, the minister and leader of the Jews of Cordoba, began his efforts to establish an independent center of Jewish culture, poetry and science in Spain.^[1] Hasdai, who sought to eclipse the dominant centers of Torah in the East, invited Dunash to Cordoba as part of gathering the finest minds of the generation.^[1] In Cordoba Dunash joined the royal court and the linguistic and literary activity there, until his death around 990.^[1] Dunash's personal life was revealed in part through the findings of the Cairo Genizah, in which delicate and melancholy poems were found that Dunash and his wife, a poet, exchanged when he was forced to wander, which attests that his wife was a unique and influential poetic figure in her own right in that period.^{[1, 2]}

His Grammatical Teaching and the Comparative-Linguistics Approach

Dunash ben Labrat's grammatical teaching laid the foundations of scientific Hebrew linguistics. He was active at a time when Hebrew grammar was still in its first stages of formation, and he sought to introduce a systematic and structural methodology for the analysis of the language. Dunash is credited with a series of morphological and syntactic innovations that students and scholars of the language use to this day:

The initial distinction between the intransitive (omed) and transitive (yotzei) verb is attributed to Dunash, who was the first grammarian to define explicitly and methodically the syntactic and semantic difference between intransitive verbs (omedim) and transitive verbs (yotz'im).^[1] This breakthrough enabled precise analysis of the relations of subject and object in the biblical sentence. In addition, Dunash was the first to propose the use of the root letters pe-ayin-lamed as a systematic model (paradigm) for the conjugation of verbs and their division into light and heavy binyanim.^[1] This development significantly simplified the description of the morphological system in Hebrew, which until then had been described in a cumbersome and inconsistent way.

Dunash championed the scientific principle that the Hebrew language should be compared with the Arabic language in order to understand difficult biblical words and to decipher ambiguous grammatical structures.^[1] He sharply criticized his contemporaries, foremost Menachem ben Saruq, who avoided this philological comparison out of an isolationist outlook.^[1] Dunash argued that the two languages share a common Semitic origin, and therefore the rules of Arabic can shed light on Hebrew. This approach aroused a fierce controversy in Cordoba and led to the writing of his famous work "His Replies to the Notebook of Menachem" (Teshuvot Dunash al Mahberet Menachem).^[1] At the same time, Dunash did not hesitate to disagree even with his primary teacher, Rav Saadia Gaon, and wrote about 200 grammatical and exegetical critiques of Rasag's translations and commentaries on Scripture, in the work known as "The Replies of Dunash ben Labrat to Rasag."^{[1, 3]} Although some scholars have suggested that the author of these critiques is a sage named Adoniyah who is not Dunash, the exegetical and scholarly tradition for the most part accepts the identification of Adoniyah as Dunash ben Labrat.^[1]

The Cordoba Controversy: A Confrontation Between Grammatical and Theological Schools

The debate between Dunash ben Labrat and Menachem ben Saruq was not merely a linguistic dispute but a deep cultural and theological struggle that shook the Jewish community in Spain and shaped the future of biblical exegesis. Menachem ben Saruq composed the "Mahberet," a comprehensive dictionary of biblical words, in which he presented a conservative approach that identifies many Hebrew roots as consisting of only one or two letters, because of a failure to recognize defective roots (such as those lacking pe-nun or ayin-vav).^{[4, 5]} Menachem believed that the Hebrew language is a unique divine language, and therefore he opposed comparing it with Arabic or any alteration of the letters of Scripture by means of methods of letter substitution or transposition.^[5]

Dunash sharply attacked Menachem's approach and accused him of a tendency toward Karaite interpretation, because Menachem proposed interpretations that were based directly on the plain meaning of Scripture and at times contradicted the midrashim of the Sages and the rabbinic tradition.^{[1, 5]} These accusations, directed to their common patron Hasdai ibn Shaprut, led to harsh political consequences: Hasdai accepted Dunash's claims, removed Menachem from his court, and sent messengers who burned his house in the midst of the Sabbath day and exiled him from Cordoba.^[5] Menachem sent Hasdai a poetic and painful rhetorical letter in which he protested the injustice done to him and claimed his complete innocence.^[5]

The controversy continued to resonate in later generations through the students of the two sages, who conducted an extensive literary war. Menachem's students—Yitzchak ben Kaprun, Yitzchak ibn Gikatilla and Yehuda ben David (later Hayyuj)—wrote the book "The Replies of Menachem's Students," in which they repelled Dunash's claims and attacked his metrical method based on Arabic.^{[4, 5]} On the other side, Yehudi ben Sheshet, one of Dunash's outstanding students, came to the defense of his teacher in a work full of anger and rhetoric ("The Replies of Dunash's Student"), in which he attacked Menachem's students in return.^{[1, 4, 5]}

Below is a table that comprehensively compares the two schools, their students, the principal works that were created in their wake and the later rulings:

The Metrical Revolution and the Establishment of the Arabic Poetic Meter in Hebrew

One of the greatest and most influential contributions of Dunash ben Labrat was the metrical revolution he brought about in Hebrew poetry.^[1] Until his time, Hebrew poetry and the piyyut of the Land of Israel and of Babylonia did not obey rigid rules of meter based on a quantitative distinction between syllables.^[8] Dunash was the first to introduce the quantitative meter of Arabic poetry into Hebrew poetry.^{[1, 8]}

The Meter of Yatedot (Pegs) and Tenuot (Movements)

Since in Hebrew there was no phonological distinction between short and long vowels such as exists in Arabic, Dunash devised an ingenious solution: he established the mobile shva and the hataf vowels as parallel to the short vowels, while the full vowels (open or closed syllables) he established as parallel to the long vowels.^{[1, 8]} This method received the name meter of yatedot and tenuot ^{[1, 8]}:

• Tenuah (movement): represents an ordinary syllable, open or closed.^[8]
• Yated (peg): consists of a mobile shva or a hataf followed by a full vowel.^[8]

Thus, for example, the poem "Libi BaMizrach" by Rabbi Yehuda HaLevi is built in the meter of "two tenuot and a yated, tenuah and yated / two tenuot and a yated, tenuah and yated," with the words divided into exact syllables: "Li-bi (tenuah-tenuah) be-miz-rach (yated-tenuah) ve-a-no-chi (yated-tenuah) be-sof ma'arav."^[8] This method remained consistent and preserved rigid rules, and it continued to influence later poets as well, including the Jews of Yemen, who used this meter until recent generations, even though the theoretical terms "yated" and "tenuah" were not formally known to them.^[8]

Menachem's students attacked this metrical revolution very sharply, claiming that Dunash was corrupting biblical Hebrew and forcing it into foreign and unsuitable molds.^[1] They showed that in order to meet the requirements of the meter, Dunash was forced to alter biblical grammatical forms, to turn quiescent shvas into mobile ones and to change the patterns of words.^{[1, 6]} Despite the criticism, the quantitative meter became the hallmark of Hebrew secular poetry in Spain, while other meters were used mainly for liturgical piyyut.^[8]

Below is a table comparing the different systems of scansion that developed in medieval Hebrew poetry:

"Dror Yikra" as a Case Study of the Metrical and Poetic Application

The piyyut "Dror Yikra" for Shabbat, composed by Dunash ben Labrat, serves as a clear case study of the practical application of his poetic and metrical teaching.^{[1, 6, 9]} The piyyut gained enormous popularity in all the dispersions of Israel, and many melodies were composed for it in various communities, such as Yemenite Jewry and Georgian Jewry, and it was even adapted to the Arabic musical maqam "Kurd."^{[6, 9, 10, 11]} The poem expresses the national longing for redemption and for liberation from enemies (Babylon and Edom) within the framework of the festivity and rest of the Sabbath day.^{[6, 11]}

In structural and poetic terms, the poem exemplifies the characteristics of Dunash's revolution:

• Acrostic: The author's name, "Dunash," is signed in the first, second, third and sixth stanzas, a tradition that confirms his authorship of the work.^{[6, 9]}
• Meter of a yated and two tenuot: The poem is built strictly according to the quantitative meter.^[1] In order to adapt the Hebrew language to the rigid metrical structure, Dunash was forced to make exceptional philological changes. A clear example is the alteration of the biblical word "בָּבָה" (babah; "apple of the eye," Zechariah 2:12) to the artificial form "בָּבַת" (babat) in the first stanza: "וְיִנְצָרְכֶם כְּמוֹ בָבַת" ("and He will guard you like the apple of the eye").^{[1, 6]} Likewise, the word "נָעִים" (na'im, with a kamatz, an adjective) was changed to a construct form with a mobile shva ("נְעִים שִׁמְכֶם"), in order to preserve the yated.^[1]
• Rich biblical allusions: The poem weaves together whole verses from diverse sources in Scripture. The phrase "and proclaim liberty throughout the land to all its inhabitants" (Leviticus 25:10) is the inspiration for the opening line; the prohibition of work on Shabbat is based on Exodus 20:9 ("you shall not do any work, you and your son and your daughter"); the description of the growth of desert trees in the last stanza ("myrtle, acacia, cypress, plane tree") is based directly on the prophecy of Isaiah 41:19 ("I will put in the wilderness the cedar, the acacia, and the myrtle... I will set in the desert the cypress, the plane tree").^[6]

In addition to "Dror Yikra," Dunash composed in the same quantitative meter of a yated and two tenuot also the opening for the invitation to the Seven Blessings meal, known as "Devai Haser," which is accepted to this day in the Ashkenazi communities.^[1] These works prove how Dunash's poetic solutions became an integral part of the Shabbat liturgy and Jewish joy throughout the generations.

The Medieval Rulings and the Controversy over the Defense of Rasag

Dunash ben Labrat's influence extended beyond his own brief life, and continued to stir controversies and stormy discussions among the greatest commentators and halakhic authorities of the Middle Ages. His works and critiques were examined again and again through the lens of textual conservatism versus systematic innovation.

Safah Yeterah by Abraham ibn Ezra

Dunash's critiques of Rasag aroused the anger of Rabbi Abraham ibn Ezra (Raavad), who saw in Rasag a supreme authority. Between 1140 and 1142, while staying in the city of Lucca in Italy, Ibn Ezra wrote the book defending Rasag known as "Safah Yeterah" (An Additional Language).^{[1, 12, 13, 14]} In this book he comes out sharply against Dunash's claims and saves Rasag's commentaries from his critiques.^{[12, 14]} Ibn Ezra praised the book in rhetorical verse: "A book, a foundation of grammar like a crown; a book that will cleanse the heart like natron; a book in the name of a disciple whose name is Chayim" ^[12], thereby seeking to re-establish Rasag's grammatical authority against Dunash's structural analysis.

The Sefer HaHakhra'ot by Rabbenu Tam

In twelfth-century France, Rabbi Yaakov ben Meir (Rabbenu Tam), one of the greatest Tosafists and Rashi's grandson, was drawn into the controversy between Menachem and Dunash and wrote the "Sefer HaHakhra'ot" (Book of Rulings; also called "Hakhra'ot Rabbenu Tam").^{[1, 3, 4]} Rabbenu Tam analyzed the claims of both sides and in most cases ruled in favor of Menachem ben Saruq against Dunash's critiques.^[1]

Rabbenu Tam's anger at attempts to change the text of the traditional wording or to invent new grammatical rules that undermine the existing ones is reflected also in his famous work "Sefer HaYashar" (the section of novellae).^[15] In his introduction to Sefer HaYashar, Rabbenu Tam comes out sharply against correctors of books who change the readings of the words of the Amoraim and the Tannaim on the basis of their personal reasoning.^[15] He mentions the ban imposed by Rabbenu Gershom, Light of the Exile, on whoever corrupts the Talmud, and notes that his grandfather, Rashi, corrected readings in his commentaries but refrained from erasing and changing the original text of the books themselves.^[15] Rabbenu Tam even attacks his brother, the Rashbam (Rabbi Shmuel), for correcting and erasing old books on the basis of external evidence and his personal dialectic.^[15] This conservative worldview of Rabbenu Tam, which grants supremacy to the inherited textual tradition over logical reconstructions, explains why he ruled in favor of the conservative grammar of Menachem ben Saruq against the Arabist and structural system of Dunash.^{[1, 5, 15]}

The Sefer HaGalui by Yosef Kimchi

Another figure who took part in deciding the controversy was Rabbi Yosef Kimchi (Rikam), who was active in southern France (Provence) and wrote the "Sefer HaGalui."^[7] This work, written entirely in Hebrew, is divided into two parts: the first part contains rulings on the linguistic disputes between Menachem and Dunash, with direct reference to the rulings of Rabbenu Tam, while the second part offers new and original critiques against Menachem.^[7] In this book Rikam presented the famous division of the vowels into five great vowels and five small vowels, and gave them a mnemonic based on precise Hebrew rhyme ^[7]:

• The great vowels: "Barukh shomer piv" ("Blessed is he who guards his mouth").^[7]
• The small vowels: "Mikol tum'at peh" ("From all impurity of the mouth").^[7]

This historical development led to the four central works of the controversy—"Mahberet Menachem," "The Replies of Dunash," "The Replies of Menachem's Students and the Replies of Dunash's Student," and "The Replies of Dunash on Rasag"—being bound and printed together throughout the generations as a foundational linguistic collection that presents the fruitful dialectic of Hebrew grammar.^{[3, 4]}

Summary and Historical Perspective

From a broad historical perspective, the work and teaching of Dunash ben Labrat constituted an unprecedented catalyst for the development of Jewish studies. Although in his time he was persecuted and his works met fierce opposition from conservative circles that saw the introduction of Arabic meter and grammar as a violation of the sanctity of the Hebrew language ^[1], the scientific principles he set became the mainstream of Semitic linguistics. Indeed, the student of his great rival, Yehuda Hayyuj ^[5], ultimately adopted the principle of comparison with Arabic that Dunash had fought for, and by means of it resolved the question of the full root and established Hebrew grammar on three fixed consonants.^[5]

Dunash's exegetical influence is evident on every page of Rashi's commentary on Scripture, which cites Dunash's words as an authoritative exegetical anchor for understanding the plain meaning of words.^{[1, 2]} His poetry, foremost the piyyut "Dror Yikra," continues to be heard every Shabbat at the tables of millions of Jews throughout the world, and thus constitutes living testimony to the victory of the formal and metrical revolution led by this sage in Cordoba more than a thousand years ago.^{[1, 6, 9]}
