Jacob Weil, later known as Mahariv was a German rabbi and Talmudist who flourished during the first half of the fifteenth century.
Biography
Of his life, few details are known, but, according to Grätz, he died before 1456. He was one of the foremost pupils of Jacob Moelin, 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. This despite the fact that Weil himself ruled that a rabbi had no lifetime tenure. Indeed, this example illustrates two facets of Weil's personality - his deep humility and his deep-felt desire to avoid unnecessary confrontation and conflict. He generally signed his responsa "the little one, Jacob Weil". Weil was later called to the rabbinate of Erfurt; and congregations far and near, recognizing him as an authority, addressed their problems to him. Among the rabbis who addressed questions to him are Rabbi Israel Isserlein and his student Rabbi Israel of Brno. Weil approved of the pilpulistic method only as an aid to study, but rendered legal decisions purely on the basis of logic. Weil was especially severe on contemporary rabbis who regarded themselves as having peculiar privileges transcending the rights of the laity, declaring in a responsum that no rabbis of his time had any such prerogatives, and that, moreover, no man could be regarded as a scholar in the Talmudic sense. Despite his humility and his belief in the value of peace, when he felt that the need arose Weill did not spare his pen. After his father in law refused to repay the debt of a man who paid the ransom of his mother in law, Weill ruled that "since I am close to the case, it is my responsibility to take action and to nullify his evil decree so that a mishap does not occur in Israel and the door is not closed on those who perform good deeds and the name of heaven is not desecrated... and if he does not obey this strict ruling he is to be cursed and excommunicated and separated from all that is holy". 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 have been the subjects of various commentaries and additions.
