Rav Schwab on Chumash

"Many of the Chiddushei Torah in this volume were originally written in Rav Schwab's magnum opus , 'Maʻayan Beis Hoshoʼeivah', and have now been carefully selected, translated, and written over. Others were original chiddushim that have never been published before, which were heard from the Rav by his family and students" -- page 4 of cover.
