 This important work—the largest of the midrashic collections—came to popular attention only in the late 19th century through the efforts of Jacob Saphir, Solomon Schecter, and David Zvi Hoffmann.In addition to containing midrashic material that is not found elsewhere, such as part of the Mekhilta of Rabbi Shimon, Midrash HaGadol contains what are considered to be more correct versions of previously known Talmudic and Midrashic passages.The existence of the "Midrash HaGadol" was first brought to the attention of Jewish scholarship by Jacob Sapir, who in his "Even Sapir" (1866) reports seeing a manuscript of the work in the possession of the Chief Rabbi of Yemen.
