One of the most defining aspects of Avraham’s relationship with God is blessing.  God is consistently blessing Avraham and promising that Avraham will be a source of blessing for others.  Although blessings are common throughout the Torah, the mechanism of blessings—what they do and how they work—can be opaque.  R. Menahem Nahum of Chernobyl, the Me’or Einayyim, sees something in the language of blessing, berakhah, which teaches us not only what it means to be blessed by God, but also what it means to live a holistic religious life.
