In this deep dive, Rabbi Heschel Greenberg uncovers one of the most elegant and profound explanations in all of Rambam’s writings. Why does the Rambam forbid a Kohen from seizing Terumah or Maaser — even with words? Why must it be taken with dignity? And how does this single characterization — that the Kohen is eating from Hashem’s table — solve one of the strongest questions Tosafot ever asked on Rashi regarding the prohibition of Tevel (untithed produce)? This is not just dry halachah. This is Rambam at his philosophical best: revealing the inner spiritual mechanics behind the mitzvah and answering a question that has bothered learners for centuries • Read More, Watch

Rabbi Heschel Greenberg unpacks one of the most fascinating technical distinctions in Rambam’s Hilchos Gittin: the rules of shlichus when a get is delivered. What happens when a shliach can’t finish the job? Can he appoint a second shliach? The answer, according to Rambam and the Rishonim, is a razor-sharp “yes… but only sometimes.” This isn’t abstract theory – it’s the practical machinery that determines whether a Jewish divorce is valid or invalid, and it reveals Rambam’s razor-sharp legal brilliance in action • Read More, Watch
