Rabbi Heschel Greenberg has launched a new series of classes on the Rambam’s Mishneh Torah in response to the Rebbe’s call to learn at least one halacha in depth.

The Rebbe initiated a major effort to unite all Jews with the study of the entire encyclopedic work, Mishneh Torah, by learning three chapters a day and completing the entire work in less than a year. Alternatively, one can learn one chapter and complete the entire Mishneh Torah in close to three years. The Rebbe also gave a third option to study Maimonides’ companion work, Sefer Hamitzvos that parallel the Mishneh Torah.

In addition, the Rebbe requested that we learn one halacha in depth.

We recently began the 46th cycle of Mishneh Torah which inspired Rabbi Greenberg to record brief classes on selected passages of the Mishneh Torah.

Rabbi Heschel Greenberg is a shliach of the Rebbe in Buffalo, NY and the Director of the Jewish Discovery Center, and, for over 50 years, has taught thousands of classes on all aspects of Jewish knowledge.

Rabbi Greenberg has also authored dozens of works on diverse subjects including several volumes of commentary on the Mishneh Torah.

Many of Rabbi Greenberg’s classes can be accessed on his website rabbigreenberg.com.

What if I told you that simply speaking words of consecration could earn you Malkus (lashes) — even though Jewish law normally requires a physical action for such a penalty? In this deep, Rambam masterclass, we unpack one of the most fascinating and counterintuitive halachos in the entire Mishneh Torah: the prohibition against sanctifying a blemished animal (Ba’al Mum) for the Mizbeach. This isn’t dry legal theory — this is a window into Rambam’s revolutionary legal mind, the power of speech in creating spiritual realities, and the profound debate between two great Rishonim (Chinuch and Lechem Mishneh) that reveals how “just words” can carry real halachic weight. Whether you’re a serious Torah student, a halacha enthusiast, or simply fascinated by how Jewish law thinks about intention, speech, and holiness, this video will transform the way you understand the gravity of our words and commitments.
