[2] Feivel was the son of Rabbi Yaakov Koppel Kamiel, an expellee of Schnaittach, Germany, and Pearl[3] (who might have actually been his grandmother),[4] a relative of Yom-Tov Lipmann Heller.
During his career, Hager didn't lead a congregation, nor did her serve on a rabbinate board, but made his living from a small resale store.
[8] According to Hasidic oral tradition, the Besht promised Hassid that the Jewish community of Maramureș would be under the rabbinate of his descendants.
[9] He was called a "Shvitinik" by the gentile population of his town due to the way that he held his hands over his eyes occasionally, even when trading, and would read the verse "Shivviti ADONAI lenegdi tamid ki mimini bal-emmot".
(Psalms 16:8)[10] In his final years, he lived in Tysmenytsia, where he helped grow the Hasidic movement in the area and defended Rabbi Meshullam Egra following a dispute that arose between him and the residents of the city.
