The Mekhilta of Rabbi Shimon ben Yochai () is midrash halakha on the Book of Exodus from the school of Rabbi Akiva attributed to Shimon bar Yochai.

No midrash of this name is mentioned in Talmudic literature, but Nachmanides (d.1270) refers to one which he calls either Mekhilta de-Rabbi Shimon ben Yochai, Mekhilta Achǝrita de-Rabbi Shimon, or simply Mekhilta Acheret. Todros ben Joseph Abulafia (d.1285) also refers to Mekhilta de-Rabbi Shimon ben Yochai. pg. 47-49

Date The current scholarly consensus is that the Mekhilta dates to the period of the Amoraim (200–500 AD).

References by later writers Passages from this Mekhilta are cited in later works, especially by Nahmanides in his Pentateuchal commentary,On Genesis 49:31; Exodus 14:19, 21:3, 22:12; Leviticus 23:24 and by Todros Abulafia in his works Sefer ha-Razim and Otzar ha-Kabod.MSS. in the Königliche Hofund Staatsbibliothek, Munich; comp. M. H. Landauer in Orient, Lit. 1845, vi. 182 et seq. Maimonides, in his Sefer Hamitzvot (assertive command no. 157), also cites from the Mekhilta of Rabbi Shimon ben Yochai.

Until the early 1900s, aside from these quotations and some given by certain authors of the 16th century (such as Elijah Mizrahi in his Sefer ha-Mizrachi, Shem-Ṭob ben Abraham in his Migdal Oz, and R. Meir ibn Gabbai in his Tola'at Ya'akovp. 63b, Cracow, 1570), the only known extract of any length from Mekhilta de-Rabbi Shimon was the one published by R. Isaac Elijah Landau from a manuscript of R. Abraham Halami, as an appendix to his edition of the Mekhilta.Vilna, 1844

There were, therefore, various erroneous opinions regarding this lost work. ZunzG. V. p. 419, note a considered it as a kabbalistic work ascribed to R. Shimon ben Yochai. M. H. Landauerl.c. identified it with the Mekhilta of Rabbi Ishmael, while J. Perlesin Monatsschrift, 1858, pp. 145 et seq. held that the medieval authors applied the name "Mekhilta de-Rabbi Shimon" merely to his maxims which were included in the Mekhilta de-Rabbi Yishmael, since separate sentences could be called "mekhilta". M. Friedmann was the first to maintainIn his introduction to the Mekhilta of R. Ismael, Vienna, 1870, pp. 54 et seq. that, in addition to R. Ishmael's work, there was a halakhic midrash to Exodus by R. Shimon, which was called the "Mekhilta de-Rabbi Shimon," and that this Mekhilta formed part of the Sifre mentioned in the Talmud Bavli.Sanhedrin 86a; Berachot 47b; Megillah 28b; Kiddushin 49a; Shevuot 41b; Hagigah 3a

This assumption of Friedmann's was subsequently confirmed by the publication of a geonic responsum,A. Harkavy, Teshubot ha-Ge'onim, p. 107, No. 229, Berlin, 1888 where a baraita from the Sifre de-Bei Rav to Exodus is quoted, which is the same passage as that cited by Nahmanides from the Mekhilta de-Rabbi Shimon ben Yochai, in his commentary on Exodus 22:12. This extract designates the work of R. Ishmael as the "Mekhilta of Palestine," in contradistinction to Shimon ben Yochai's midrash. It is clear, therefore, that the Mekhilta of R. Shimon was implied in the title Sifre de-Bei Rav;Compare David Zvi Hoffmann, Einleitung in die Halachischen Midraschim, p. 46 and it is mentioned in the Midrash Tehillimed. S. Buber, Wilna, 1891, p. 252 (comp. Buber's note there) under the Hebrew name Middat Rabbi Shimon ben Yochai.

It is possible also that Shimon himself intended to refer to his midrash in his saying: "My sons, learn my middot; for my middot are the finest of the finest middot of Rabbi Akiva".Gittin 67a The Judean sources, the Yerushalmi and the aggadic midrashim, introduce baraitot from this Mekhilta with the phrase, "Tanei Rabbi Shimon" = "Rabbi Shimon has taught".Compare Friedmann, introduction to his edition of the Mekhilta, pp. 55 et seq.; Hoffmann, l.c. p. 48 The phrase "Tana de-Bei Rabbi Shimon" is extremely rare, however, in the Talmud Bavli, where this midrash ranks as one of the "Sifre de-Bei Rav".Hoffmann, l.c. p. 50 Many sentences of Shimon are quoted there in the name of his son Eleazar, so that Hoffmann has very plausibly concludedl.c. p. 51 that Eleazar edited his father's midrash.

Current status The Mekhilta de-Rabbi Shimon had disappeared, but some extracts from it were preserved in the collection known as Midrash haGadol, as Israel Lewy first pointed out.Israel Levy, Ein Wort über die Mechilta des R. Simon (Jahrsbrecht), Breslau 1889 (in German) These fragments were collected by David Zvi Hoffmann and published under the title Mechilta de R. Simon b. Jochai.In the Hebrew monthly Ha-Peles, Volumes 1 to 4, passim

This Mekhilta compiled from Midrash haGadol preserves abundant material from the earliest Scriptural commentaries, quoting, for instance, a sentence from the Doreshei Reshumot on Exodus 21:12Ha-Peles, iii. 258 which is found nowhere else. It contains also much from post-Talmudic literature,Compare Hoffmann, l.c. p. 387, note 19 for the collector and redactor of the Midrash haGadol had a peculiar way of dressing sentences of such medieval authorities as Rashi, Ibn Ezra, Arukh, and Maimonides in midrashic garb and presenting them as ancient maxims.Compare S. Schechter, Introduction to Midrash ha-Gadol, p. 13, Cambridge, 1902

A critical version, using newly discovered fragments of texts, was later published by Yaakov Nahum Epstein and his student Ezra Zion Melamed. (first edition: ) The publication is an attempt to reconstruct the original Mekhilta of Rabbi Shimon ben Yochai, based on all extant sources.
