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 46nd 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.

Why doesn’t a house in Yerushalayim ever become tamei from a nega, even though the same house anywhere else in Eretz Yisrael would? The Rambam’s answer opens up a real machlokes about who actually owned Yerushalayim—and whether the Beis HaMikdash itself was ever divided among the shevatim.

The Rambam rules (Hilchos Tumas Tzara’as 14:11) that Yerushalayim and chutz la’aretz are not subject to tumas nega’im, because the halacha only applies to “a house in the land of your inheritance” (b’veis eretz achuzaschem)—and Yerushalayim, the Rambam holds, was never divided among the shevatim.
