(Mishnah): Yisraelim are Yotzei [Simchah] with Nedarim and Nedavos and Ma'aser Behemah. Kohanim are Yotzei with [also] Chatas and Asham, Chazah v'Shok and Bechor, but not with birds or Menachos.

(Gemara - R. Ze'irah citing Ula bar Yishmael citing R. Lazar): If one slaughtered Shalmei Chagigah on Erev ha'Regel (Erev Yom Tov ha'Rishon), he was not Yotzei through them his obligation on the Regel [even for Simchah].

Question (R. Ba - Beraisa): Chagigah of the 14th (a Shelamim brought with Pesach, in order to be satiated with Kodshim before eating Korban Pesach), one is Yotzei Simchah through it, but he is not Yotzei Shelamim (Chagigah) through it.

Answer (R. Ze'irah): That is when he [was Makdish it for Chagigah of the 14th, but] slaughtered it during the Regel.

Objection (R. Ba): If he slaughtered it during the Regel, it is not Chagigah of the 14th! (It is a Stam Neder or Nedavah.)

Question: What was the conclusion?

Answer (R. Ze'irah): When I was there (in Bavel), I heard what Ula bar Yishmael said [above] in the name of R. Lazar. When I came to here (Eretz Yisrael), I heard R. Chiyah teach [a Beraisa] in the name of R. Lazar;

(Beraisa): "V'Hayisa Ach Same'ach'' includes the night of Yom Tov Acharon for Simchah.

Question: Perhaps [it includes] even the night of Yom Tov Rishon!

Answer: "Ach'' (excludes, i.e. it does not include both).

Question: Perhaps it is oppositely! (We include the night of Yom Tov Rishon, and exclude the night of Yom Tov Acharon.)

Answer (R. Chiyah citing R. Lazar): "V'Samachta b'Chagecha'' - from when you are obligated in Chagigah, you are obligated in Simchah. (What was slaughtered Erev Regel does not help.)

Question (Mishnah - Sukah 4:1): Hallel and Simchah apply [every day of Sukos, i.e.] eight days;

Exert yourself [and you will find the answer]! If Yom Tov Rishon was on Shabbos, [how can one fulfill Simchah then]? You cannot slaughter it Erev ha'Regel, for R. Ze'irah citing Ula bar Yishmael citing R. Lazar said that if one slaughtered Shalmei Chagigah on Erev ha'Regel, he was not Yotzei through them his obligation on the Regel;

You cannot slaughter it during the Regel, for we already learned that Chagigah is not Docheh Shabbos!

Question: When did they say that Hallel and Simchah are eight? (Do not say that it is when Yom Tov is not on Shabbos. If so, it should have taught "Simchah is seven or eight'', just like the Reisha taught that Lulav and Aravah are six or seven!)

Answer (R. Yosi): Rav Avodimi Nechusa answered, Kohanim [can fulfill Simchah eight days. On the first day, it is] through the goat (the Chatas Tzibur of Yom Tov. They eat it raw, for one may not cook it on Shabbos.)

(Mishnah): [Kohanim] are not [Yotzei] through birds or Menachos.

This is because it says "Zevach'' (something slaughtered).

(Mishnah): If one has many eaters (people in his household) and little property, he brings many Shelamim and few Olos. If one has few eaters and much property, he brings many Olos and few Shelamim;

If both of these (eaters and property) are few, about this it was said Ma'ah Kesef and two Kesef (he brings just one Chagigah and one Olas Re'iyah, for the minimal amount).

If both of these are many, about this it was said "Ish k'Matnas Yado k'Virkas Hash-m Elokecha Asher Nasan Lach'' (he brings according to how much he was blessed).

(Gemara): If an Oni [normally] spends much, I apply to him "Ish k'Matnas Yado'' (he may not skimp on Shelamim). If an Ashir [normally] is frugal, I apply to him "k'Virkas Hash-m Elokecha Asher Nasan Lach'' (he must bring according his wealth).

If an Oni is frugal, about this it was said not [to spend] less than two Kesef [and Ma'ah Kesef. We explained this like SEDEI YEHOSHUA.]

"Ish'' excludes a minor. (Even though a boy who can ascend with his father is obligated in Olas Re'iyah, like it says above (1a), he is exempt from Chagigah. Alternatively, he is totally exempt; his father is commanded about him - HA'GAON RAV C. KANIEVSKY, SHLITA.)

Question (R. Yirmeyah): If one said "it is Alai to bring a Chagigah for five Sela'im'', was he Yotzei [Chagigah], or was it already set (that he must bring a Chagigah for five Sela'im)?

Answer (R. Yosi): Why should he not [be Yotzei]? If someone [was obligated an Asham, and he] said "it is Alai to bring an Asham for five Sela'im'', perhaps [if he offered for two, he was not Yotzei the Korban, and] it is not set (he must fulfill his vow through another three for Mosar Asham, i.e. Nedavah?! Surely he was Yotzei and it is set!) And here [also, he is Yotzei Chagigah, and] it is set (he must bring Shelamim for another three Sela'im to fulfill his vow.)
