 From 1828 until his death he was chief rabbi of the grand duchy of Weimar, residing first at Lengsfeld and later at Eisenach.Although the measure had aroused great dissatisfaction among the Jews, he strictly enforced the decree of the government (June 20, 1823) ordaining that Jewish services should be conducted exclusively in the German language and that the reading in Hebrew of sections of the Bible should be followed by their translation into the vernacular.The position of rabbi as government official became very unpleasant, as he was required to inform against those who failed to attend the services, a requirement which even the progressive Jews, who approved of the ordinance, condemned.
