Yefet ben 'Eli (fl. 960-1005) was the most prolific and influential biblical exegete in the Karaite tradition. He was possibly the earliest Jew to write a commentary on the entire Hebrew Bible, and his writings were cited and borrowed from by Karaites and Rabbanites alike, from his own time to the early modern period. Despite his importance, however, only a small percentage of his works have been published. The present volume makes available for the first time his commentary on Joshua, which includes an Arabic translation of this difficult book with full Arabic commentary. The story of Rachab, the "second circumcision," the covenant with the Gibonites, and the Sun standing still are among the things that captured Yefet's interest, who surveyed different views on these crux passages before presenting his own, very original exposition.
