R. Bachiah ben Asher ben Chalawa (13th-century), Dayan of Saragossa, was a Kabbalist of the school of R. Solomon ibn Adret of Barcelona (the Rashb"a). His Commentary here is one of the most influential encyclopedic works on the Torah. Utilizing a wide variety of sources, noteworthy are his Kabbalistic references, Midrashic interpretations as well as citations from lost Midrashim. The immense popularity of Rabbeinu Bachiah’s work is attested to by the dozens of super-commentaries that have been written upon it.
