Meilah in Konamot: Title vs. Monetary Ownership in Hekdesh

This shiur delivers a comprehensive analysis of meilah (misappropriation) in the context of konamot (vows formulated like hekdesh), reconciling an apparent contradiction in the Rambam (רמב"ם) and establishing a fundamental distinction between title and monetary ownership in hekdesh. The shiur opens with a steira (contradiction) in the Rambam. In Perek Dalet Hilchos Meilah (10), the Rambam rules according to Rav Amar that when someone says "kikar olecha hekdesh" (this loaf is to you like hekdesh) and gives it, the nosen is not mo'el because lo asur alo (it's not prohibited to him), and the mekabel is not mo'el because he can say "had I known it was prohibited, I wouldn't have wanted to acquire it"—yet he is mo'el kashyotzi (when he removes it from hekdesh's domain). The Ran explains this is because had the mekabel known it was prohibited, he wouldn't have wanted to acquire it, so there's no meilah on kabbalah b'shogeg (receiving unknowingly). However, in Perek Vav (7), the Rambam discusses a case where both nosen and mekabel are mo'el, and states clearly that if both act b'shogeg, the second person is not mo'el only because it already exited to chulin (yotza l'chulin). This implies that a mekabel b'shogeg would be mo'el if not for yotza l'chulin—a direct contradiction to Perek Dalet.
