 While he refused to hold the office of a rabbi, he was for many years one of the "dayyanim" (judges) of the Wilna community.His chief merit, in addition to his work in these two posts, was his valuable services rendered to the Jews of Wilna and to those of all Russia in representing their interests before the Russian government.From 1849, when he was chosen as a delegate by the Jewish community of Wilna, he was always the representative speaker on behalf of that important community.
