However, between day and night people do not err, and therefore there is no concern that they might have erred in this regard. And similarly, by right we should give them even more leeway at the end of the period. However, this too is not a reasonable discrepancy, as at five hours of the day the sun is in the east and at seven hours the sun is in the west. No one confuses the morning with the afternoon.,In light of the above conclusions, the Gemara returns to address the issue of leaven. We learned in the mishna that Rabbi Meir says: One may eat leaven the entire fifth hour of the fourteenth of Nisan, and one must burn it immediately afterward at the beginning of the sixth hour. Rabbi Yehuda says: One may eat the entire fourth hour, and one places it in abeyance for the entire fifth hour, and one burns it at the beginning of the sixth hour.,The Gemara raises a difficulty: According to Abaye’s explanation in accordance with the opinion of Rabbi Meir, that he said a person does not err about the time at all, let him eat leaven for the entire sixth hour, as by Torah law it is permitted to eat until the end of the sixth hour, i.e., midday. The Sages issued a decree prohibiting the consumption of leaven from the beginning of the sixth hour, lest one unwittingly come to eat after midday. However, according to Rabbi Meir, people do not err in this regard at all and that concern is unfounded. And according to that version of Rabbi Meir’s opinion, that he said a person errs a bit, let him eat leaven until just before the end of the sixth hour.,And according to Abaye’s explanation in accordance with the opinion of Rabbi Yehuda, that he said: A person errs by half an hour; let him eat leaven until the midpoint of the sixth hour. And even according to the version of Rabbi Yehuda’s opinion, that he said: A person errs by an hour plus a bit; let him eat leaven until just before the end of the fifth hour. From the fact that this is not the ruling of these Sages, apparently Abaye’s assessment of the amount of time that a person errs is incorrect.,Rather, Abaye said: There is a difference between the issues of testimony and leaven, as testimony is entrusted to the vigilant. One comes to testify only if he thoroughly scrutinized the subject of his testimony. Therefore, he will not err significantly with regard to the time in question. However, the prohibition against eating leavened bread is a halakha entrusted to all, and not everyone is able to correctly determine the time. Consequently, Rabbi Meir and Rabbi Yehuda both extend the margin for error, so that people will not unwittingly eat leaven after the time that it is prohibited to do so.,The Gemara raises another difficulty: And according to Rava’s explanation in accordance with the opinion of Rabbi Meir, that he said: A person errs by two hours less a bit; from the beginning of the fifth hour let one no longer eat leaven. After all, one could confuse the fifth hour with the seventh hour, when it is prohibited to eat leaven by Torah law. The Gemara answers: Since at five hours the sun is in the east and at seven hours the sun is in the west, no one confuses morning with afternoon.,The Gemara raises a difficulty: If so, during the sixth hour let him eat leaven as well, as one distinguishes between the sixth hour and the seventh hour since the sun tends westward only during the seventh hour. Rav Adda bar Ahava said: In the sixth hour, the day, i.e., the sun, stands at the meridian, equidistant between east and west, and it is unclear toward which direction it tends. Therefore, confusion between the sixth and seventh hours is possible.,The Gemara asks: And according to Rava’s explanation in accordance with the opinion of Rabbi Yehuda, that he said: A person errs by three hours less a bit; from the beginning of the fourth hour let one no longer eat leaven. The Gemara answers: If, since at five hours the sun is in the east and at seven hours the sun is in the west, one does not confuse the morning with the evening, and all the more so one will not confuse seven hours of the day with four hours of the day, when the sun is further east. The Gemara raises a difficulty: If so, i.e., there is no concern lest one confuse morning and afternoon, during the fifth hour let him eat leaven as well.,Abaye interpreted it in accordance with the opinion of Rava: Testimony is entrusted to the vigilant, and therefore a witness is less likely to err, whereas the prohibition against eating leavened bread is entrusted to all. Since a common person is more likely to err, the Sages were more stringent with regard to leaven than with regard to testimony.,And Rava said: That is not the reason for the added hour in the opinion of Rabbi Yehuda, as he is not concerned lest people err. Rather, Rabbi Yehuda conforms to his standard line of reasoning, as he said: The removal of leaven can be performed only by burning it, and therefore by prohibiting the consumption of leaven, the Sages provided him with one hour during which to gather wood to burn the leaven.,Ravina raised an objection to the opinion of Rava from a baraita. Rabbi Yehuda said: When is it that the elimination of leaven can be performed only by burning it? It is only when one removes the leaven not at the time designated for its removal. Then, one should seek out the preferred method of removal and implement it in the ideal manner. However, when one removes the leaven at the time designated for its removal, at the end of the sixth hour when he must remove the leaven immediately, the removal of leaven may be performed in any manner, and one need not seek wood for burning. Why, then, was it necessary for the Sages to provide him with an hour to gather wood?,Rather, Rava reconsidered the previous explanation and said: It is a rabbinic decree due to a cloudy day, when one is unable to observe the precise position of the sun, increasing the likelihood of confusion. The Gemara raises a difficulty: If so, then even at fourth hour let one no longer eat leaven, as according to Rabbi Yehuda a person errs by three hours less a bit. Rav Pappa said: The fourth hour is mealtime for everyone, and therefore everyone is aware of that hour and will not confuse it with another.,In light of Rav Pappa’s statement, the Gemara discusses the topic of mealtimes. The Sages taught in a baraita: Eating in the first hour of the morning is the time of eating for Ludim, who are members of a nation of cannibals, and they are ravenous and in a hurry to eat. The second hour is the time of eating for robbers [listin]. Since they spend the night stealing, they eat early in the morning. The third hour is the time of eating for heirs, i.e., people who inherited a lot of money and do not work for their sustenance. Their only preoccupation in the early hours of the morning is eating. The fourth hour is the time of eating for workers. The fifth hour is the time of eating for Torah scholars. The sixth hour is the time of eating for all people.,The Gemara raises a difficulty: But didn’t Rav Pappa say that the fourth hour is the time of eating for all? Rather, reverse the fourth, fifth, and sixth hours: The fourth hour is mealtime for all people, the fifth hour is the time of eating for workers, and the sixth hour is the time of eating for Torah scholars.,One who eats from this point forward does not benefit from eating, as he is like one who throws a stone into a leather bottle, i.e., it does not contribute to his health. Abaye said: We only said that eating from the sixth hour onward is not beneficial, when he did not taste anything in the morning; however, if he tasted something in the morning we have no problem with it.,Rav Ashi said: Like the dispute between Rabbi Meir and Rabbi Yehuda with regard to testimony, so too is their dispute with regard to leavened bread. The Gemara comments: This is obvious, as this is precisely that which we said. The Gemara explains: Rav Ashi comes to teach us that the answers that we answered, distinguishing between the cases of testimony and leaven, are legitimate answers. And do not say that the different rulings in the two cases reflect a dispute between tanna’im with regard to the opinions of Rabbi Meir and Rabbi Yehuda and the answers are merely forced attempts to resolve the contradiction but not legitimate answers.,Rav Shimi bar Ashi said: They taught that the court does not reject testimony due to a discrepancy over time only with regard to testimony ascribed to different hours of the day. However, if one witness says that the incident occurred before sunrise and the other one says it occurred after sunrise, their testimony is void. The Gemara asks: It is obvious that this is the case, as a blatant contradiction of this kind could not possibly be the result of miscalculation.,Rather, emend the previous statement: If one witness says the incident occurred before sunrise and one says it occurred during sunrise, their testimony is void. The Gemara asks: That too is obvious, as the difference between those times is similarly conspicuous. The Gemara answers: It is necessary to teach this halakha, lest you say that both of the witnesses are saying one matter, and the fact that one witness says
