Rabbi Moshe ben Nachman, the 13th century Jewish leader and scholar known as Ramban, earned himself a place alongside Rashi as one of Judaism's primary Torah commentators. His commentary, which encompasses a vast panorama of Jewish learning -- language, halachah (Jewish law), philosophy, Kabbalah (Jewish mysticism), and history -- offers a penetrating analysis of the Torah that will both enlighten and inspire. Rabbi Dr. Chavel's elegant English translation is based on the original Hebrew manuscripts. Insightful notes offer clarification of Ramban's commentary and provide his sources.
