Jacob Ben Judah Weil, later known as Mahariv (Hebrew: יעקב בן יהודה ווייל) was a German rabbi and posek who as one of the Rishonim, was an active Talmudic authority during the first half of the fifteenth century.

Weil's main teacher was Jacob Moelin (the Maharil), who ordained Weil into the rabbinate, and appointed him to the rabbinate in Nuremberg and to establish a yeshiva there.
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 (Maharya) 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.
Of Weil's works only a collection of opinions and decisions, "She'elot u-Teshubot" (Venice, 1549; republished in Hanau, 1610), 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.

This appendix was printed separately in Amsterdam for the first time, and is offered here at auction.
