Exhaustive supercommentary by R. Elijah Mizrachi (c. 1455 – 1525) on Rashi's commentary on the Torah. The work shows Rashi's Talmudic and midrashic sources, and elucidates obscure passages. Now counted in its own right as among the most important commentaries on the Torah, it was written, partially, to defend Rashi from the arguments of the later commentators, particularly Ramban.
