Yefet ben Ali


Yefet ben Ali was perhaps the foremost Karaite commentator on the Bible, during the "Golden Age of Karaism". He lived during the 10th century, a native of Basra Later in his life, he moved to Jerusalem, between 950 and 980, where he died. The Karaites distinguished him by the epithet maskil ha-Golah.
His commentaries were written in Judeo-Arabic, and covered the entire Tanakh. They were accompanied by a very literal translation of the Hebrew text, which often violated the rules of Arabic grammar. These writings influenced the rabbinical sage Abraham ibn Ezra, who quotes Yefet forty-two times in his commentary of the minor prophets.

Approach

Unlike his Karaite predecessors in the field of Bible exegesis, Yefet realized the importance of grammar and lexicography for the interpretation of Scripture, although he did not excel in either. The interest which his commentaries present lies chiefly in the accumulation of material for the history of the differences between traditional Judaism and the Karaites; for he enters into lengthy disputes with traditional rabbis, especially with Saadia, from whose commentaries on the Bible and polemical works, including some no longer in existence, he gives many extracts. Thus in regard to Ex. xxxv. 3 he discusses with Saadia the kindling of a fire by a non-Jew on Sabbath, a practise which the Karaites considered to be forbidden. Yefet reproaches Saadia with being unfaithful to the principles he himself had laid down for the interpretation of the Law, according to which no deductions by analogy are admissible in definite revealed precepts. On Lev. xxiii. 5 Yefet cites fragments from Saadia's "Kitab al-Tamyiz", a polemical work against Karaism, in which the author states that there are three sects which are divided on the question of the new moon: the Rabbinites, who, except in special cases, determine it by the molad; the sect of the Tiflis, which follow the molad absolutely; and a sect which is guided by the first appearance of the moon.

Exegesis

Yefet claims full freedom for the exegete, refusing to admit any authority for the interpretation of the Law; and, although he sometimes uses the thirteen hermeneutic rules laid down in the Mishnah, he denies their authority: they are to be applied, he claims, only when it is not possible to explain the passage literally. Thus, notwithstanding his veneration for Anan ben David, the founder of Karaism, and for Benjamin Nahawandi, he often rejects their interpretations.
Yefet was an adversary of the philosophico-allegorical treatment of Scripture. He, however, symbolizes several Biblical narrations, as, for instance, that of the burning bush, in which he finds a representation of Israel, whom enemies can not annihilate; and he admits that the Song of Solomon is an allegory.
Yefet attacked Islam with the greatest violence. For him the words of Isaiah, "Woe to thee that spoilest", refer to Mohammed, who robbed all nations and dealt treacherously with his own people, and Isa. xlvii. 9 to the downfall of Islam. In the following verse he sees an allusion to the sufferings inflicted by Muslim rulers on the Jews, who are loaded with heavy taxes, compelled to wear badges, forbidden to ride on horse-back, etc.
Yefet was no less bitter in his attacks on Christianity and on rabbinical Judaism, to which he refers many prophecies. Unlike his predecessors, he was not an opponent of secular science. To him the word "da'at" denotes "the knowledge" of astronomy, medicine, mathematics, etc., the study of which is to be undertaken before that of theology.

Influence

Yefet's commentaries were much used by succeeding Karaite exegetes, and were often quoted by Ibn Ezra. Written in Arabic, some of them were rendered into Hebrew either in full or abridged.
Nearly the whole Arabic text on all the Biblical books is extant in manuscript in European libraries. The parts which have been published are: on the Psalms and the Song of Solomon, by Abbé Bargès ; on Proverbs, by Z. Auerbach ; on Hosea, by Tottermann and M. Polliack and E. Schlossberg ; on Daniel, by Margoliouth ; on Ecclesiastes i.-iii., by E. Günzig ; on Ruth, by N. Schorstein ; on Esther by M. Wechsler by P. D. Wendkos, unpublished phd thesis and Joshua A. Sabih, ; Judaeo-Arabic translation, J. A. Sabih.

Other works

He was also known for his expertise of Hebrew grammar, and for his polemics against Rabbinic Judaism, Islam, and Christianity. One of his comments about the Rabbanites, writing on his Arabic commentary on Isaiah, Yefet ben Ali digresses as follows: "This section refers to the people of the Diaspora and to the best among them as well. They are at present divided into four classes :
  1. The Exilarchs who pretend to be the possessors of knowledge;
  2. The common people who neither desire wisdom nor think about it; they know no more about religion than to go to the Synagogue from Sabbath to Sabbath and to say "Amen" and "shema Yisrael";
  3. The studious among the common people, whom the Exilarchs teach them the nonsense of the Talmud, and sorcery, instead of what might profit them;
  4. The "Maskilim".
Before devoting himself to Biblical exegesis Yefet wrote several other works of lesser importance. Among these were:
