Rabbi Heschel Greenberg has created a series of classes on the Rambam's Mishneh Torah, focusing on a halacha concerning the prohibition of deriving benefit from forbidden items through sensory perception.
The class examines a teaching from the Rambam's Hilchos Meila: the sound, sight, and fragrance of consecrated items may not be benefited from. While there is no biblical violation in merely looking, hearing, or smelling such items, the Chachamim imposed a rabbinic prohibition. The Rambam extends this principle to other areas of issur hana'ah throughout Jewish law, including chametz on Pesach.
The series was prompted by a call to learn at least one halacha in depth. The Rebbe initiated an effort for Jews to study the Mishneh Torah, offering multiple approaches: three chapters daily for completion in under a year, one chapter daily for completion in roughly three years, or study of the companion work Sefer Hamitzvos.
Greenberg, a shliach in Buffalo, New York and director of the Jewish Discovery Center, has taught thousands of classes on Jewish subjects over more than five decades and authored numerous works including volumes of Mishneh Torah commentary. The recent start of the 46th cycle of Mishneh Torah study inspired him to record these focused classes on selected passages. His classes are available on rabbigreenberg.com.
