Les Nombres 9:2 Références de la Michna : Mishnah Megillah & Mishnah Pesachim

On Pesah we read from the portion of the festivals in Leviticus (Torat Kohanim) (Leviticus 23:4). On Shavuot, “Seven weeks” (Deuteronomy 16:9). On Rosh Hashanah “On the seventh day on the first of the month” (Leviticus 23:2. On Yom Hakippurim, “After the death” (Leviticus. On the first day of the Festival [of Sukkot] they read from the portion of the festivals in Leviticus, and on the other days of the Festival [of Sukkot] the [sections] on the offerings of the Festival.

These things in [connection with] the pesah override Shabbat: its slaughtering and the sprinkling of its blood and the cleansing of its innards and the burning of its fat. But its roasting and the washing of its innards do not override Shabbat. Carrying it and bringing it from outside the Shabbat border and cutting off its wart do not override Shabbat. R. Eliezer says they do override [Shabbat].

Rabbi Eliezer said: is it not logical: if slaughtering, which is [usually forbidden] as a labor, overrides Shabbat, shouldn’t these, which are [only forbidden] as mandated rest (shevut), override Shabbat? Rabbi Joshua said to him: let the festival prove this, for they permitted labor [on the festival] and forbade [activities forbidden because of] shevut. Rabbi Eliezer said to him: what is this, Joshua? What proof is a voluntary act in respect of a commandment! Rabbi Akiva answered and said: let sprinkling [purificatory waters] prove it, which is [performed] because it is a commandment and is [forbidden only] as a shevut, yet it does not override Shabbat; so you too, do not wonder at these, that though they are [required] on account of a commandment and are [forbidden only] as shevut, yet they do not override Shabbat. Rabbi Eliezer said to him: but in respect of that I am arguing: if slaughtering, which is a labor, overrides Shabbat, is it not logical that sprinkling, which is [only] a shevut, should override Shabbat! Rabbi Akiva said to him: or the opposite: if sprinkling, which is [forbidden] as a shevut, does not override Shabbat, then slaughtering, which is [normally forbidden] on account of labor, is it not logical that it should not override Shabbat. Rabbi Eliezer said to him: Akiva! You are uprooting what is written in the Torah, “at twilight, offer it at its set time” (Numbers 9:3), both on week-days and on Shabbat. He said to him: master, give me an appointed time for these as there is an appointed season for slaughtering! Rabbi Akiva stated a general rule: work which could be done on the eve of Shabbat does not override Shabbat; slaughtering, which could not be done on the eve of Shabbat, does override Shabbat.
