Bava Metzia 55 - 1st Day of Pesach, April 23, 15 Nissan

If one misuses consecrated property unknowingly, one must repay the value and add one-fifth (chomesh). Rabbi Yehoshua ben Levi held that the additional one-fifth payment is not added if one is redeeming a secondary hekdesh, an item that was sanctified from an item that was already sanctified (via hatpasa). The Gemara questions a statement made in a braita that was brought to support Rabbi Yehoshua ben Levi and resolves it. Another braita is brought as support for Rabbi Yehoshua ben Levi. The Mishna lists the minimum amount of money for ona'ah and partial admission (modeh b'miktzat). It also lists five laws for which the minimum amount is a pruta. Levi has a different list of the five laws and the Gemara discusses why each list differs from the other. The Mishna lists 5 cases where one needs to add one fifth. One of the items is d'mai – a case where there is reason to think that ma'asrot (tithes) may not have been taken and the rabbis required one to separate the tithes just in case. Rabbi Elazar questions why the Mishna lists that one would add one-fifth if a non-kohen ate truma taken from d'mai, which is only truma by rabbinic law. Why would it be treated as stringently as a Torah obligation? They answer that the Mishna is according to Rabbi Meir's approach that the rabbis make their decrees as strong as the Torah as is proven from a case of divorce law where Rabbi Meir is stringent. However, they raise a difficulty with saying that this is Rabbi Meir's position.
