Ketubot 18 - July 24, 25 Tamuz

Why didn’t the Mishna mention a case of one who claimed that they borrowed money from another, but already paid it back? Why didn’t it mention the case of one who said “Your father lent me money but I paid him back half.” Rabbi Eliezer ben Yaakov and the rabbis disagree regarding that case – what does each hold and why? Why is it different than a standard case of modeh b’miktzat, one who admits to part of the claim, who is obligated to swear regarding the half in question? The Mishna brings another case where one is believed as we only know of the claim at all from what the person told us and therefore, they are believed about the rest. The case is regarding verification of signature on a document. When the witnesses verified their signatures, they claimed they were forced into it or were too young to testify or were disqualified witnesses. Rami bar Chama limits one of the cases of the Mishna but there are two versions as to which one he is limiting. How does the Mishna work with the principle that once one has testified, one can no longer change their testimony? How does it work with the principle that a person does not come to court and self-incriminate themselves? A braita brings a debate between Rabbi Meir and the rabbis regarding the law in our Mishna. The Gemara raises a difficulty with Rabbi Meir’s opinion.
