Yoma 3A

פז״ר קש״ב.

Peh, zayin, reish, kuf, shin, beit, an acronym for: Lottery [payis], as a new lottery is performed on that day to determine which priests will sacrifice the offerings that day, and the order established on Sukkot does not continue; the blessing of time [zeman]: Who has given us life, sustained us, and brought us to this time, is recited just as it is recited at the start of each Festival; Festival [regel], as it is considered a Festival in and of itself and there is no mitzva to reside in the sukka (see Tosafot); offering [korban], as the number of offerings sacrificed on the 8th Day is not a continuation of the number offered on Sukkot but is part of a new calculation; song [shira], as the Psalms recited by the Levites as the offerings were sacrificed on the 8th Day are not a continuation of those recited on Sukkot; blessing [berakha], as the addition to the third blessing of Grace after Meals and in the Amida prayer (see Tosafot) is phrased differently than the addition recited on Sukkot.

אבל לענין תשלומין, תשלומין דראשון הוא, דהא תנן: מי שלא חג ביום טוב הראשון של חג ⁠— חוגג והולך כל הרגל כולו, ויום טוב האחרון של חג.

However, despite all these differences, with regard to compensation for failure to sacrifice the Festival offerings at the earliest opportunity, everyone agrees that it is a day of compensation for obligations not met during the first Festival, as didn’t we learn in the Mishnah: One who did not celebrate on the first Festival day of Sukkot by sacrificing the Festival offering may celebrate and sacrifice the Festival offering throughout the whole Festival in its entirety, including the last Festival day of the festival of Sukkot. Apparently, the 8th Day of Assembly is considered the last Festival day of Sukkot and is appended to it with regard to its obligations.
