בחולין שנעשו על טהרת תרומה ורבי יהושע לא ס"ד דקתני בשר דאי בתרומה בשר מי איכא with regard to the case of non-sacred food items that were prepared on the level of purity of teruma and in accordance with the opinion of Rabbi Yehoshua. The Gemara responds: It should not enter your mind that the mishna is referring to a case of the level of purity of teruma, as the mishna teaches a case of the slaughter of animals and birds and consumption of their meat. And if the mishna is taught with regard to non-sacred food items that were prepared on the level of purity of teruma, is there meat eaten with the level of purity of teruma? The practice of preparing non-sacred food items on the level of purity of teruma is done only so that one will not treat actual teruma in the correct manner, and teruma is separated only from produce that grows in the ground.
אלא מאי בקדשים חיה בקדשים מי איכא בשר בבשר מיחלף בשר בפירי לא מיחלף The Gemara asks: Rather, what is the case in the mishna? Is it a case of non-sacred food items that were prepared on the level of purity of sacrificial food? Is there an undomesticated animal that can be sacrificed as an offering and its meat is sacrificial food? The Gemara answers: Although undomesticated animals cannot be sacrificed as an offering, there are those who would undertake to eat their meat only when prepared on the level of purity of sacrificial food because meat of an undomesticated animal is sometimes interchanged with meat of a domesticated animal. No one would undertake to eat meat only when prepared on the level of purity of teruma, because meat would not be interchanged with produce.
אמר עולא חבריא אמרין בחולין שנעשו על טהרת הקדש ודלא כרבי יהושע Ulla said: My colleagues say that the mishna is referring to the case of non-sacred food items that were prepared on the level of purity of sacrificial food, and the mishna is not in accordance with the opinion of Rabbi Yehoshua, who says: Non-sacred food items that were prepared on the level of purity of teruma assume third-degree impurity, but non-sacred food items that were prepared on the level of purity of sacrificial food do not assume third-degree impurity.
ואנא אמינא רבי יהושע היא ולא מיבעיא קאמר לא מיבעיא חולין שנעשו על טהרת קדש דחמירי דאית בהו שלישי אלא אפילו חולין שנעשו על טהרת תרומה נמי אית בהו שלישי Ulla continues: And I say that the mishna is in accordance with the opinion of Rabbi Yehoshua, and when he said that non-sacred food items that were prepared on the level of purity of teruma assume third-degree impurity, he is speaking utilizing the style of: It is not necessary. It is not necessary to say that in the case of non-sacred food items that were prepared on the level of purity of sacrificial food, which is stringent, that they have the capacity of assuming third-degree impurity. Rather, even non-sacred food items that were prepared on the level of purity of teruma also have the capacity of assuming third-degree impurity.
מאן חבריא רבה בר בר חנה היא דאמר רבה בר בר חנה א"ר יוחנן מאי אהדרי רבי אליעזר ורבי יהושע להדדי The Gemara asks: Who are the colleagues to whom Ulla referred? It is Rabba bar bar Ḥana, as Rabba bar bar Ḥana says that Rabbi Yoḥanan says: What did Rabbi Eliezer and Rabbi Yehoshua reply to each other? The differences between their opinions are twofold. First, Rabbi Eliezer holds that one who eats food with first-degree impurity assumes first-degree impurity, while according to Rabbi Yehoshua he assumes second-degree impurity. Second, Rabbi Eliezer holds that one who eats food with third-degree impurity assumes third-degree impurity, while according to Rabbi Yehoshua he assumes second-degree impurity vis-à-vis sacrificial food but not vis-à-vis teruma.
אמר לו ר"א לרבי יהושע מצינו אוכל חמור מן האוכל דאילו נבלת עוף טהור בחוץ לא מטמא ואילו אוכלה מטמא בגדים אבית הבליעה ואנו היאך לא נעשה אוכל כמאכל Rabbi Eliezer said to Rabbi Yehoshua: The basis for my opinion that one assumes the level of impurity of that which he ate is that we found a case where the halakha of the one who eats a food item is more stringent than the halakha of the food itself. As, the carcass of a kosher bird on the outside, i.e., when one comes into contact with it, does not impart ritual impurity, while one who eats the carcass of the kosher bird renders his garments impure when the food is in his throat. And we, in light of that, how will we not deem one who eats the impure item to be on a level of impurity at least like that of the food that he ate?
ורבי יהושע מנבלת עוף טהור לא גמרינן דחידוש הוא אלא מצינו שהמאכל חמור מן האוכל דאילו מאכל בכביצה ואוכל עד דאכיל כחצי פרס ואנו היאך נעשה אוכל כמאכל And Rabbi Yehoshua responded that we do not derive other cases from the case of the carcass of a kosher bird, because it is a novel ruling that cannot serve as a paradigm. Rather, we found that the halakha of food is more stringent than the halakha of the one who eats it, as food becomes impure if its measure is that of an egg-bulk, and one who eats impure food does not become impure until he eats half of a half-loaf. And we, in light of that, how will we deem one who eats the impure item to be on a level of impurity like that of the food that he ate?
ור"א טומאה משיעורין לא גמרינן ועוד לדבריך שאתה אומר על ראשון שני יפה אתה אומר שני שני למה And Rabbi Eliezer responded: We do not derive the relative stringency of ritual impurity from the relative size of halakhic measures, as measures are not indicative of stringency or leniency. And furthermore, according to your statement, that which you say with regard to one who eats food with first-degree ritual impurity, that he assumes second-degree impurity, what you say is well. But that which you say with regard to one who eats food with second-degree impurity, that he assumes second-degree impurity, why is that the case? It contradicts your reasoning.
אמר לו מצינו שהשני עושה שני ע"י משקין Rabbi Yehoshua said to Rabbi Eliezer: We found that food with second-degree impurity renders other food impure with second-degree impurity by means of liquids. Liquids that come into contact with food with second-degree impurity render other food with which they come into contact impure with second-degree impurity.
אמר לו והא משקין נמי תחלה הוו דתנן כל הפוסל בתרומה מטמא משקין להיות תחלה חוץ מטבול יום Rabbi Eliezer said to him: But aren’t those liquids also impure with first-degree ritual impurity through contact with an item impure with second-degree impurity? As we learned in a mishna (Para 8:7): Any item with second-degree ritual impurity that disqualifies teruma renders liquids impure with first-degree ritual impurity. These liquids assume a degree of impurity greater than that of the item that rendered them impure. This rabbinic decree applies to all people and items with second-degree impurity except for one who was ritually impure who immersed that day and is waiting for nightfall for the purification process to be completed. Liquids with which he comes into contact follow the standard course of transmitted impurity and assume third-degree impurity, one level below his own impurity.
ועוד שלישי שני למה Rabbi Eliezer questioned the next segment in the ruling of Rabbi Yehoshua: And furthermore, that which you say with regard to one who eats food with third-degree impurity, that he assumes second-degree impurity vis-à-vis sacrificial food, why is that the halakha? It contradicts your reasoning.
אמר לו אף אני לא אמרתי אלא בתרומה שטהרתה Rabbi Yehoshua said to Rabbi Eliezer: I too stated that one who eats food with third-degree impurity assumes second-degree impurity vis-à-vis sacrificial food only with regard to one who eats non-sacred food items that were prepared on the level of purity of teruma, as its state of purity
