How what happened in the Temple made it into our liturgy. Specifically, how the musaf sacrifice is represented in the musaf prayer service. Which is necessarily based on the complications of an ambiguous calendar, when t days if each Jewish month can shift, depending on the witnesses who come to the Temple to testify to the new moon. Including our practice today if reading both possible day's passages. Also, dividing the mishmarot, and the division of sacrifices over the holiday. Plus, saying goodbye to the holiday, in the way the offerings first represent all of the nations of the world, and count down to the one sole offering on the last day of Sukkot. Also, one more mishnah - on the offerings and the mishmarot, how each mishmar was responsible for the daily sacrifices of that week.
