I noticed that there are three moments called Atzeret.
- The seventh day of Pesach (Deuteronomy 16:8)
- Shavuot (Pesachim 68b)
- Shemini Atzeret (Leviticus 23:36)
But what is the connection between these three specific moments?:
Although all three are called Atzeret the one of Pesach is a 'seven' celebration, Shavuot a 'eight after seven' celebration, and Shemini a 'eight' celebration.
Although connected to Sukkot Shemini Atzeret isn't one of the Shalosh Regalim, while Pesach and Shavuot Are.
Although Pesach was necessary in order for us to receive the Torah, only Shavuot (Matan Torah) and Shemini Atzeret (Simchat Torah) celebrate Torah.
Although it's been said that the relationship of Shemini Atzeret to Sukkot is the same as that of Shavuot to Passover. Pesach shevi'i is a Atseret, but the shevi'i of Sukkot isn't. Besides the Atzeret of Pesach (Shavuot) comes after 7x7+1 and the Atzeret of Sukot after 7+1...
I can think of so many connections, but none of these seem to fit all three moments. Is there a connection between Pesach, Shavuot and Sukkot (in any order taken)?
I have the impression I'm missing or overlook some things to connect this properly. Please help me out..
