Jacob Weil, later known as Mahariv (Hebrew: יעקב בן יהודה ווייל) was a German rabbi and Talmudist who flourished during the first half of the fifteenth century. He was one of the foremost pupils of Jacob Moelin (Maharil), who ordained him in the rabbinate, and authorized him to officiate in Nuremberg. Weil, however, did not avail himself of this permission lest he should offend an older scholar, Solomon Cohen, who had been appointed rabbi of that city long before. Weil was later called to the rabbinate of Erfurt; and congregations far and near, recognizing him as an authority, addressed their problems to him. Of Weil's works only a collection of opinions and decisions, "She'elot u-Teshubot", has been preserved. To this work was added an appendix entitled "Sheḥiṭot u-Bediḳot," containing regulations for slaughtering and for the examination of slaughtered cattle. These rules have been regarded as authoritative by later rabbis, have run through seventy-one editions, and the responsa have been the subjects of various commentaries and additions.
