Rambam In-Depth: The Halacha That Forbids Smelling Chametz on Pesach!

Welcome tRambam In-Depth: Hilchos Meila, Perek 5, Halacha 9

Can looking at something be “deriving benefit” from it? Can smelling something be forbidden even when eating it obviously is? In this shiur we unpack a fascinating and often overlooked halacha in the Rambam’s Hilchos Meila — one that reshapes how we think about issur hana’ah (forbidden benefit) far beyond the Beis Hamikdash.

The Rambam teaches that Kol, Mar’eh, v’Reach shel Hekdesh — the sound, sight, and fragrance of something consecrated — may not be benefited from. There’s no biblical (Torah-level) violation in merely looking, hearing, or smelling, but the Chachamim forbade it rabbinically all the same. From this single halacha, the Poskim extend the principle to other areas of issur hana’ah throughout Shas — Basar b’Chalav, Chametz on Pesach, and beyond.

🔎 In this video we explore:

• Why looking at Hekdesh is forbidden even without a biblical violation
• The Pri Chadash’s example: a kernel of chametz inscribed with pesukim
• The Maharam Shik’s application to studying medicine from a stillborn corpse
• The Tur (Yoreh Deah 142) and Rabbeinu Yerucham on gazing at scenery tied to Avodah Zarah
• The Marshag’s pushback — using a Shor Haniskal and a beautifully baked chametz cake as counter-proof
• Why the Alter Rebbe (Shulchan Aruch, siman 442) forbids smelling chametz fragrance on Pesach regardless of original intent
• How the Marshag ultimately distinguishes “benefiting from looking” vs. “benefiting from what you learn by looking”
