This book presents an edition and English translation of a medieval commentary on the book of Hosea that was written by an anonymous Karaite author in the Middle Ages. The text has been established by joining together hundreds of small fragments that have been preserved in the Cairo Genizah collections. The edited work is written in Judaeo-Arabic (Arabic in Hebrew letters). The publication includes copious notes, which clarify the meaning and background of the text. This book brings into the light of scholarship an important but hitherto lost text in the intellectual history of the Karaites.
