Miriam Goldstein examines the commentary on the Pentateuch authored in the late tenth century by Yusuf ibn Nuh, a leader of the Karaite scholarly community in Jerusalem, and revised and updated by his student Abu al-Faraj Harun. Goldstein examines the work ́s historical background and reception, as well as its exegetical method, a combination of traditional Jewish techniques with methods inspired by the Arabic-Islamic environment. The resulting examination serves as a general introduction to the Karaite school of Judeo-Arabic exegesis (10th/11th c. C.E.), a crucial link between traditional rabbinic literature and the Jewish Bible exegesis of Europe. This book is intended for students of the Bible and biblical exegesis and of medieval Jewish and Middle Eastern history, as well as those simply curious to learn more about this vibrant period of creative composition in Judeo-Arabic.
