This volume consists of an English translation of Sadan's edition (published in KTS 12) of the Arabic translation and commentary on the book of Job by one of the preeminent litterateurs of the Karaite "Golden Age" (10th-11th centuries), Yefet ben 'Eli ha-Levi. This English translation grants readers access to one of the earliest systematic witnesses to Jewish exegetical thought--and hence its history and development--on this fascinating biblical book, among both Karaites as well as Rabbanites.
