[If] someone declares cherem his son or daughter, his Hebrew manservant or maidservant, and his acquired land, they do not become cherem, because a person cannot render cherem something that is not his. Kohanim and Leviim cannot declare a cherem; [these are] the words of R’ Yehudah. R’ Shimon says: Kohanim cannot declare a cherem, because the charamim belong to them; [however,] Leviim can declare a cherem, because the charamim do not belong to them. Rabbi said: The view of R’ Yehudah is indicated with respect to real property, as it says (Lev. 25:34): For it is an eternal holding for them; and the view of R’ Shimon with respect to movable property, inasmuch as the charamim do not belong to them.
