Rabbi Moshe Yehudah Leib Erblich, popularly known as Rabbi Moshe Leib of Sassov, (c. 1745 – January 13 1807) was one of the early Hasidic rebbes in 18th century Europe.
[1][4] He later went on to study under the Maggid of Mezritch himself as well as Rabbi Elimelech of Lizhensk.
[5] He was a contemporary of Hasidic rebbes Rabbi Levi Yitzchak of Berditchev, the Kozhnitzer Maggid, and the Chozeh of Lublin.
After a stint in Opatów, Rabbi Erblich moved to Sasiv where he established the hasidic court of Sassov,[4] which attracted many followers.
[4] He died on January 13, 1807, in Sasiv and was succeeded as rebbe by his son, Rabbi Yekusiel Shmuel Shmelke Erblich.
