The major medieval Karaite exegete, Yefet ben `Eli (Jerusalem, 10th century), wrote commentaries on the entire Hebrew Bible. His innovativeness and literary achievements had a formative effect on the development of medieval Jewish Bible exegesis as a whole. The book presents to the reader, for the first time, a critical annotated edition of Yefet`s central work on biblical prophecy, containing an extensive Introduction, the Judaeo-Arabic source text of Yefet`s translation and commentary on Hosea (with full manuscript apparatus), and a modern Hebrew translation, richly annotated in relation to comparative Rabbinic and Karaite sources.
