Son of Rav Sholom Segal of Zbaraz. Son-in-law of Rav Yosef Yuska of Alik Rav Aryeh Leib was one of the great disciples of the Mezritcher Maggid. He was Rav in Voltshisk which borders Galicia and Volhyn and was considered among the giants in Torah among the chassidim. Afterwards, he was offered the rabbonus of Jassi, but he refused it and offered it to his son, Rav Yosef Yuska instead. He himself left for Eretz Yisroel in תקסה and settled in Tiveria.
He was counted among the rabbonim and gaonim that the Kozhnitzer Maggid consulted regarding the aguna of Stashuv. He became a mechutan with Rav Nachman of Breslov and the Chozeh of Lublin when their descendants married. Rav Tzvi Hirsch, the son of the Chozeh, married his daughter.
His sons, Rav Pinchos and Rav Chaim Feivish, as well as his son-in-law, Rav Duvid Koppel Horowitz, a grandson of the Chozeh, all moved to Eretz Yisroel together with him. They settled in Tzefas and established a chassidic center independent from the one in Tiveria that was under the Vitebsker and Kalisker. This is why their aliyah is not mentioned in the letters of Tiveria and their signatures do not appear among them.
He passed away 23 Tammuz 1813 תקעג and was laid to rest in Tzefas between the Arizal and the Bais Yosef. His burial place is in the maaras kevura--the same cave, together with Rav Dovid Shlomo Eibshitz of Soroka, author of Arvei Nachal and Rav Avrohom Dov Auerbach of Avritsh, author of Bas Ayin.
His other children who remained in the diaspora were: Rav Yosef Yuska of Jassi; the wife of Rav Yeshaya Leib, son of Rav Yosef Moshe of Krasna; the wife of Rav Tzvi Hirsch, the son of the Chozeh of Lublin. In Chayei Moharan it mentioned that his son, Maharash, married in Berditchev, perhaps to the daughter of Rav Levi Yitzchok? Many other details about his family in Eretz Yisroel are unknown. We know that his son, Rav Chaim Feivish, survived the earthquake of תקצז, and that he went on to marry the daughter of Rav Yaakov Shimshon of Shpetivka who was also in Eretz Yisroel.
