A maggid (Hebrew: מַגִּיד), also spelled as magid, is a traditional Jewish religious itinerant preacher, skilled as a narrator of Torah and religious stories. A chaplain of the more scholarly sort is called a darshan (דרשן‎). The title of maggid mesharim ('a preacher of uprightness'; abbreviated מ"מ‎) probably dates from the sixteenth century.

There have long been two distinct classes of leaders in Israel—the scholar and rabbi, and the preacher or maggid. That the popular prophet was sometimes called "maggid" is maintained by those who translate מַגִּיד מִשְׁנֶה‎ (maggid mishne) Zechariah 9:12, by "the maggid repeats" (Löwy, "Beqoret ha-Talmud," p. 50). Like the Greek sophists, the early maggidim based their preaching on questions addressed to them by the multitude. Thus the Pesiqta, the first collection of set speeches, usually begins with "yelammedenu rabbenu" ('let our master teach us'). An excellent example is the Passover Haggadah, which is introduced by four questions; the reciter of the answer is called the maggid. When there were no questions, the maggid chose a Biblical text, which was called the petichah (opening).

The term maggid comes from Jewish mysticism (see Magid) and originally referred to a celestial entity, most commonly an angel, who manifests itself as a voice delivering mystical secrets to a kabbalist, or sometimes speaking through the mouths of the chosen ones.

The greater popularity of the maggid as compared with the darshan is instanced from aggadic (homiletical or narrative material, as opposed to legal halachic material) stories in the Talmud (main text of Rabbinic Oral Torah discussion). The Talmud relates that the people left the lecture-room of R. Chiyya, the darshan, and flocked to hear R. Abbahu, the maggid. To appease the sensitive Chiyya, Abbahu modestly declared, "We are like two merchants, one selling diamonds and the other selling trinkets, which are more in demand" (Sotah 40a).Talmudic Sages like Rabbi Meir combined the functions of a darshan and a maggid (Sanhedrin 38b). When Rabbi Isaac Nappaha was requested by one in his audience to preach a popular haggadah, and by another a halakic discourse, he answered, "I am like the man who had two wives, one young and one old, and each wishing her husband to resemble her in appearance; the younger pulled out his gray hair while the older pulled out his black hair, with the result that he became entirely bald." R. Isaac thereupon delivered a lecture that embraced both halakah and aggadah (Bava Kamma 60b).

Levi ben Sisi, his son Joshua, and others were at the head of a regular school of rabbinical maggidim. R. Ze'era was opposed to their methods of twisting and distorting the Biblical verses to suit their momentary fancy. In Ze'era's estimation their works were of no more value than books on magic (Yer. Ma'as. iii. 9). In the Gaonic period and in the Middle Ages the principal of the yeshivah, or the rabbi, delivered a lecture before each festival, giving instructions in the laws governing the days of the festival. The maggid's function was to preach to the common people in the vernacular whenever occasion required, usually on Sabbath afternoon, basing his sermon on the sidra of the week. The wandering, or traveling, maggid then began to appear, and subsequently became a power in Jewry. His mission was to preach morality, to awaken the dormant spirit of Judaism, and to keep alive the Messianic hope in the hearts of the people. The maggidim's deliverances were generally lacking in literary merit, and were composed largely of current phrases, old quotations, and Biblical interpretations which were designed merely for temporary effect; therefore none of the sermons which were delivered by them have been preserved.

Maggidism reached a period of high literary activity in the 16th century. The expulsion of the Jews from Spain in 1492 revealed a master maggid in Isaac Abravanel. His homiletic commentary on the Bible became an inexhaustible source of suggestion for future maggidim. In his method of explaining every chapter, preceded by a number of questions, he followed the early maggidim and sophists. His long argumentations in an easy and fluent style were admirably suited to the purposes of a maggid. Moses Alshech, a maggidic scholar, was one of a community of great Jewish spiritual figures who shaped Jewish thought, in the 16th-century town of Safed in the Galilee. Others in his circle included the compiler of the Shulchan Aruch code, Yosef Karo, and the leading Kabbalists Moses Cordovero and Isaac Luria. In the mystical environment of this community, the Alshech preached every Sabbath before large audiences. Isaac Luria attended his expositions, which included Kabbalistic aspects. In his classic Biblical commentaries he followed closely the method of Abravanel. Alshech also became an authority for the maggidim, who quoted him frequently.

The persecutions of the Jews brought forth a number of maggidim who endeavored to excite the Messianic hope as a balm to the troubled and oppressed Jewry. The new articulation and cosmic doctrines of redemption in Kabbalah, taught by Isaac Luria in the 16th century, inspired a new mystical awareness and focus on Messianism. Messianic messengers and potential candidates sought to advance the Messianic quest in Judaism. Asher Lemmlein preached in Germany and Austria, announcing the coming of the Messiah in 1502, and found credence everywhere. Solomon Molcho preached, without declaring the date of the advent, in both Italy and Turkey, and as a result was burned at the stake in Mantua in 1533. R. Höschel of Cracow (d. 1663) delighted in the elucidation of difficult passages in the midrash known as the "Midrash Peli'ah" ('wonderful, obscure midrash'). H. Ersohn's biography of Höschel, in his "Chanukkat ha-Torah" (Pietrkov, 1900), gives a collection of 227 "sayings" gathered from 227 books by various writers, mostly Höschel's pupils. These sayings became current among the maggidim, who repeated them on every occasion. Some maggidim copied his methods and even created a pseudo-Midrash Peli'ah for the purpose of explaining the original ingeniously in the manner initiated by R. Höschel. Behr Perlhefter is considered the first Maggid of the Sabbatian Abraham Rovigo in Modena. Perlhefter restored the Sabbatian theology after the death of the pseudo-Messiah, and advocate of mystical heresy, Sabbatai Zevi (1626-1676).

Elijah ben Solomon Abraham ha-Kohen of Smyrna, in the beginning of the eighteenth century, published his "Shebet Moussar", which he divided into fifty-two chapters, one for each week. This book caused him to be known as the "Terror Maggid"; he preached moral and religious conduct as a safeguard against the terrible punishments of the day of judgment. Dante could not picture the horrors of hell and the punishments awaiting the wicked more minutely than did the author of the "Shebet' Musar". It established a new "fire and brimstone" school of maggidim. Musar ('admonishment') is a thread in traditional Jewish thought that seeks ethical inspiration, integrity or admonishment to motivate religious devotion. Classic texts of ethical guidance from the Middle Ages articulate spiritual and psychological levels to righteousness. The later 19th century Musar movement sought to incorporate spiritual introspection and self-analysis into the scholarly yeshiva curriculum. The Musar movement seeks to inspire spiritual advancement by discovering personal integrity and revealing the unworthiness of material temptations. Its spirituality does not always describe rewards and punishments, but admonishment can be a factor. It can draw ethical lessons from Jewish mysticism, but is often compared and contrasted with the mystical paths to inspiration of Kabbalistic dveikus (cleaving to God), and the popularisation of mystical fervour in Hasidism. Typically, Hasidism avoids rebuke of punishments, replacing it with shame and remorse from nullification of self-awareness, before the omnipresent Divine presence that awakens joy.
