Mishnayos Pesachim Perek 6 Mishnah 2

Rabbi Eliezer said: Could this not be derived through an a fortiori inference? If slaughter, which is ordinarily forbidden on Shabbat as a biblically prohibited labor, nonetheless overrides Shabbat when performed for the sake of the Paschal lamb, then these activities, namely carrying the animal, bringing it from outside the Shabbat limit, and the like, which are prohibited due to rabbinic decree, should they not override Shabbat? Rabbi Yehoshua said to him: The law governing a Festival proves otherwise, for the Torah permitted on it acts that are normally prohibited as labor, such as slaughtering, cooking, and baking, and yet it is forbidden to do on it acts that are prohibited due to rabbinic decree. Thus, we cannot derive policy with regard to rabbinic prohibitions from the rules that govern Torah laws. Rabbi Eliezer said to him: What is this, Yehoshua? How can you suggest such a weak proof? What proof can be deduced from optional activities that would apply to a mitzva? How does the fact that rabbinic decrees remain in effect on a Festival with respect to optional activities prove that one is also forbidden to transgress a rabbinic decree in order to fulfill the mitzva of offering the Paschal lamb? Rabbi Akiva responded and said in defense of Rabbi Yehoshua’s opinion: Sprinkling the purifying water of a red heifer upon someone who had contracted ritual impurity through contact with a corpse proves the matter, for it is done for the sake of a mitzva, in order to allow the person to offer the Paschal lamb, and it is prohibited only due to rabbinic decree, and nonetheless it does not override Shabbat, for the purification rite is not performed on the eve of Passover that falls on Shabbat. So, too, you should not be surprised about these activities, namely carrying the animal, bringing it from outside the Shabbat limit, and cutting off its wart, that although they are performed for the sake of a mitzva and they are prohibited only due to rabbinic decree, they do not override Shabbat. Rabbi Eliezer said to him: I do not accept this proof. With regard to this sprinkling itself, I infer that it, too, is permitted for the same reason: If slaughter, which is a biblically prohibited labor, overrides Shabbat, is it not right that sprinkling the purifying water of a red heifer, which is prohibited only due to rabbinic decree, should override Shabbat? You cannot challenge me based on a premise with which I disagree. Rabbi Akiva said to Rabbi Eliezer: Or perhaps we can reverse the order of your argument and say the opposite: If, as we know by accepted tradition, sprinkling the purifying water on Shabbat, which is prohibited only due to rabbinic decree, does not override Shabbat, then with regard to slaughter, which is prohibited as a biblically prohibited labor, is it not right that it should not override Shabbat? Therefore, it should be prohibited to slaughter the Paschal lamb when the eve of Passover occurs on Shabbat. Rabbi Eliezer said to him: Akiva, how can you say this? You have thus uprooted what is written in the Torah: “Let the children of Israel offer the Paschal lamb in its appointed time” (Numbers 9:2); the phrase “at its appointed time” indicates that the offering must be brought on that day, whether it is a weekday or Shabbat. Rabbi Akiva said to Rabbi Eliezer: My teacher, bring me an appointed time stated in the Torah for these tasks, namely, carrying the animal or bringing it from outside the Shabbat limits, like the appointed time stated with respect to slaughter. The Paschal lamb must be slaughtered on the fourteenth of Nisan, but there is no fixed time when the animal must be brought to the Temple, and it is therefore possible to transport it before Shabbat. Rabbi Akiva stated a principle: Any prohibited labor required for the offering of the sacrifice that can be performed on the eve of Shabbat does not override Shabbat; slaughter, which cannot be performed on the eve of Shabbat, overrides Shabbat.
