The Alter Rebbe wrote this letter of condolence to his Chasidim in 1788 after the passing of his colleague and mentor, the saintly R. Mendele of Vitebsk (or Horodok), who had settled in the Holy Land in 1777. It concludes by rousing them to the mitzvah of tzedakah in general and particularly of maintaining the family of R. Mendel.
