He is also referred to by the Hebrew acronym מהרצ"א. Tzvi Elimelech was a nephew of Elimelech of Lizhensk and a student of Menachem Mendel of Rimanov, Yaakov Yitzchak of Lublin and Yisroel Hopstein.
The traditions of Zvi Elimelech Spira continue among his descendants and followers in Brooklyn.
Rabbi Spira's best known work is the Bnei Yissaschar ( בני יששכר; "Tribe of Issachar").
[2] It discusses mystical aspects of the Sabbath and festivals and is arranged according to the months of the year.
The title of the work is based on the verse "Of the Issacharites, men who knew how to interpret the signs of the times" (I Chronicles 12:33), an allusion to the book's explanation of the Jewish festivals.
