Maggid (Hebrew: מַגִּיד), sometimes spelled as magid, is a traditional Eastern European Jewish religious itinerant preacher, skilled as a narrator of Torah and religious stories. A preacher of the more scholarly sort was called a "darshan", and usually occupied the official position of rabbi. The title of "maggid mesharim" (= "a preacher of uprightness"; abbreviated מ"מ) probably dates from the sixteenth century.
There always have 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) Zecharia 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 "maggid." When there were no questions the maggid chose a Biblical text, which was called the "petichah" (opening).
