 While the required quorum for most activities requiring a quorum is usually ten, the Korban Pesach must be offered before a quorum of thirty — it must be performed in front of "kahal adat yisrael", the assembly of the congregation of Israel; ten are needed for the assembly, ten for the congregation, and ten for Israel.According to some Talmudic authorities, such as Rav Kahana IV, women counted in the "minyan" for offering the passover sacrifice (B.Pesachim 79b).Even if the eve of the Passover fell on a Sabbath, the Passover lamb was killed in the manner described above, the blood was sprinkled on the altar, the entrails removed and cleansed, and the fat offered on the altar; for these four ceremonies in the case of the Passover lamb, and these alone, were exempt from the prohibition against working on the Sabbath.
