Yefet Ben Ali - Approach

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: (1) the Rabbinites, who, except in special cases, determine it by the molad; (2) the sect of the Tiflis, which follow the molad absolutely; and (3) a sect which is guided by the first appearance of the moon.
