Commentary for Pesachim 198:6
אמר מר זוטרא מאן לימא לן דמתרצתא היא
R'Jose said: He may go on eating until nightfall! - Said R'Huna: This [our Mishnah] is necessary only on the view of R'Jose, who said: He may go on eating until nightfall: that is only on the eves of Sabbaths and [other] Festivals; but with respect to the eve of Passover he agrees [with R'Judah], because of the duty of [eating] unleavened bread.<span class="x" onmousemove="('comment',' For since the eating of unleavened bread on the first night of Passover is compulsory (v. Ex. XII, 18) it is unfitting that should be eaten when one is already satisfied.');"><sup>7</sup></span> R'Papa said: You may even say [that it must be taught on] R'Judah['s view too]: there, on the eve of Sabbaths and Festivals, it is forbidden only from minhah and after, but close to minhah it is permitted; whereas on the eve of Passover it is forbidden even close to minhah too. Now is it permitted just before minhah on the eve of the Sabbath and Festivals? Surely it was taught: A man must not eat on the eve of the Sabbath or Festivals from nine hours<span class="x" onmousemove="('comment',' I.e., about three p.m., whereas minhah time was nine and a half hours, about half past three p.m., two and a half hours before nightfall.');"><sup>8</sup></span> and onwards, in order that he may enter the Sabbath with an appetite: [these are] the words of R'Judah. R'Jose said: He may go on eating until nightfall? - Said Mar Zutra: Who is to tell us that this is authentic?
