Mekhilta

Mekhilta, derived from the Mishnaic Hebrew term middah, is used to denote a compilation of Jewish exegesis attributed to a handful of members of Chazal.
There are three major Mekhiltas:

The Mekhilta of [Rabbi Ishmael], a midrash halakha on the book of Exodus attributed to Rabbi Ishmael.
The Mekhilta of [Rabbi Shimon ben Yochai], a midrash halakha on the book of Exodus attributed to Rabbi [Shimon ben Yochai].
The Mekhilta le-Sefer Devarim, a midrash halakha on the book of Deuteronomy that was edited in the third century BCE before going missing. Michal Bar-Asher Siegal, a Rabbinic Judaism scholar at Ben-Gurion University of the Negev, and Avi Shmidman, a lecturer at Bar-Ilan University, collaborated with Dicta to reconstruct the Mekhilta le-Sefer Devarim by employing computational textual analysis on Rabbi David ben Amram Adani's Midrash HaGadol, a 13th- or 14th-century Yemeni midrash aggadah.
