Rabbi Joseph B. Soloveitchik (the Rav) was the towering rabbinic thinker of the twentieth century. In addition to his wellspring of Torah knowledge, the Rav taught, wrote and lectured extensively on Chumash. The Rav, however, never wrote a systematic commentary on Chumash, and, until now, the only way to study his interpretation and analysis of Chumash was to search for pertinent material by wading through the Rav's published writings and hard-to-find audio tapes of his lectures and shiurim. Now, for the first time, the Rav's teachings on Chumash have been collected into a published commentary on Sefer Bamidbar(The Book of Numbers). Commentary by the Rav on the weekly Haftarah is included.
