Musar for Shabbat 296:9
ואי לא ניתנה ליתבע מאי משמט שאני התם דאיגלאי מילתא דחול הוא
what does it cancel! — There it is different, because it is [retrospectively] revealed that it was a weekday.<span class="x" onmousemove="('comment',' Sc. the last day of Elul, in spite of the fact that it was celebrated as New Year. ');"><sup>13</sup></span> Come and hear [a refutation] from the second clause: 'but if not, it does not cancel the debt'. Now, it is well if you say that it can be claimed, hence he teaches [that] it does not cancel [the debt]; but if you say that it cannot be claimed, then what is meant by 'it does not cancel [the debt]'? — That if he [the debtor] pays him, he accepts it: whence it follows that the first clause means that [even] if he pays him he must not accept!<span class="x" onmousemove="('comment',' Surely not! The year of release does not actually cancel debts but merely deprives the creditor of his right to exact them. ');"><sup>14</sup></span>
