This volume contains an English translation of the Arabic translation and commentary on the book of Proverbs composed by one of the most acclaimed, innovative, and prolific exegetes of the Karaite “Golden Age” (10th –11th centuries), Yefet ben ʿEli ha-Levi. A critical edition and an extensive introduction was published by Ilana Sasson as vol. 1 (KTS 8) in 2016. Dr. Sasson worked for many years on an English translation of the work and, before her untimely death in 2017, passed her unfinished manuscript to the series editors. The translation was then completed, edited, and prepared for publication by Dr. Wechsler. Yefet’s commentary on Proverbs is a masterpiece of literary and rational-contextual analysis of one of the most difficult and important books of wisdom in the Hebrew Bible. His work is an invaluable link in the history of interpretation of the book of Proverbs.
