Grand Rabbi Shimon Nathan Nata Biderman, Admur Lelov-Karlin-Bnei Brak

Lelov (Yiddish: לעֶלוֹב) is a Polish-Israeli Hasidic dynastic court, which traces its origins to the town of Lelów, Poland where the court was established in 1815 by Rabbi Dovid Biderman (1746-1814).

The Lelover dynasty migrated from Poland to Jerusalem when Rabbi Dovid's son, Rabbi Moshe Biderman (1776-1851), moved there in the last year of his life. Rabbi Moshe Biderman of Lelov was the son-in-law of Rabbi Yaakov Yitzchak Rabinowicz, known as the Yid Hakudosh (Holy Jew) of Peshischa. Since then the Hasidism bore a Jerusalem character and has become part of the Old Yishuv. Today there are several descendants as Lelover Rebbes, in Bnei Brak, Jerusalem, Beit Shemesh and Brooklyn.
