 Having displeased Veitel-Heine Ephraim, one of the most influential leaders of the community, by rendering a judgment against him, he was compelled at the expiration of his term of office (1734) to resign.After having been for seven years rabbi of Metz he became chief rabbi of Frankfort-on-the-Main; but the unfavorable attitude of the local authorities toward the Jews, and the fact that the community was divided by controversies, made his position there very precarious.Soon afterward, the quarrel between Rabbis Yaakov Emden and Yonatan Eybeschütz broke out.
