Lelov (Hasidic dynasty)
Lelov is the name of a Hasidic dynasty which traces its origins to Rabbi Dovid Biderman (1746-1814) of Lelów, Poland.
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 Holy Jew of Prshischa. Today there are several Lelover Rebbes, in Bnei Brak, Jerusalem, and New York.
