2 R. Eliezer said: Should this not follow a fortiori, viz.: Now if slaughtering, which [though it is forbidden on Shabbath with chullin (i.e., for secular purposes)] being an absolute labor, [notwithstanding this,] it overrides the Sabbath [with the Pesach offering], — these ("enablers"), which are (forbidden by reason of) shvuth, should they not certainly override the Sabbath! R. Yehoshua said to him: This argument is overturned by (what obtains on) a festival, absolute labor [(like slaughtering and cooking) being permitted to all men], and shvuth activities being forbidden [e.g., They forbade the bringing of something from outside the tchum to be eaten, in that this could have been done the day before, even though tchum is a rabbinic ordinance]. R. Eliezer rejoined: What is this, Yehoshua? How can you compare reshuth (what is merely permitted) to mitzvah? [A man's eating is reshuth, but the requirement of the Most High is mitzvah. And if the sages established their shvuth interdict with reshuth, should they do so also with mitzvah! (And R. Yehoshua holds that all "festival joy" is mitzvah, in spite of which it does not override the Sabbath)]. R. Akiva answered and said: Haza'ah (the sprinkling of the purifying waters) will overturn (R. Eliezer's argument), viz.: Haza'ah is a mitzvah [in the instance of one who has become unclean through a dead body, whose seventh day (in the process of purification) falls out on Sabbath on Pesach eve. If he is not sprinkled upon he cannot bring his Pesach offering, in spite of which haza'ah does not override the Sabbath, this being the ruling espoused by R. Akiva], and haza'ah is shvuth, [a man seeming to be "amended" thereby], and it does not override the Sabbath! Therefore, you, too, should not wonder about these ("enablers"). Even though they (the "enablers" of the Pesach offering) are mitzvah, and they are shvuth factors, they do not override the Sabbath. R. Eliezer rejoined: But I question that, too [i.e., I differ on haza'ah, too, and I contend that it should override the Sabbath so that it not keep him from the Pesach — from this a fortiori argument itself], viz.: Now if slaughtering, which is an absolute labor, overrides the Sabbath, haza'ah which is (only) a shvuth interdict, should it not certainly override the Sabbath! R. Akiva rejoined: Or turn it around [i.e., I can turn the argument around. (For it was axiomatic to R. Akiva that haza'ah kept one back from the Pesach offering, so that it could be reasoned a fortiori that slaughtering should also keep him back)], viz.: Now if haza'ah, which is (only) a shvuth interdict, does not override the Sabbath, slaughtering, which is an (absolute) labor — how much more so should it not override the Sabbath! R. Eliezer rejoined: Akiva, you have uprooted what is written in the Torah, viz. (Numbers 9:3): "towards evening, in its appointed time" [(Ibid. 2)): "Let the children of Israel offer the Pesach in its appointed time"], whether on a weekday or on the Sabbath. R. Akiva answered: My master, bring me "an appointed time" for these ("enablers")! [i.e., Show me that they have an appointed time as slaughtering does. Therefore, since they have no appointed time, and they could have been performed the day before, they do not override. (And haza'ah, too, is not a function of the Pesach offering itself, and "an appointed time" is not written in respect to it.) The halachah is in accordance with R. Akiva.] R. Akiva stated a rule: Any labor which could have been done Sabbath eve does not override the Sabbath. Slaughtering (of the Pesach), which could not have been done Sabbath eve, overrides the Sabbath.
