The Jews who had returned to the Land of Israel with Ezra and Nehemiah gathered on this day and repented their misdeeds, signing a document in which they committed to trust in G‑d and follow His ways. Among the mitzvot they specified were to refrain from intermarriage and from purchasing produce on Shabbat (Nehemiah 9:1–3; 10:1–32).

On this day in 5756 (1995), the Ribnitzer Rebbe, Rabbi Chaim Zanvil Abramowitz, passed away. For decades, with great self-sacrifice, he lived a full Chassidic lifestyle under Soviet rule before emigrating to Israel and then the U.S.
The day following a festival is called Isru Chag ("tied to the festival"). Tachnun (confession of sins) and similar prayers are omitted throughout the remainder of the festive month of Tishrei.
It is not so much that we need to be taken out of exile.
It is that we must take the exile out of ourselves.
What is exile? It is the belief that there is some place outside of G-d.
And that in that place, there are forces stronger than G-d.
And those forces will not allow you to do what your soul came here to do.
Fear no thing, no force, no being other than G-d. Do that which you must do as though nothing stands in your way.
Then you will have taken yourself out of exile. And G-d will complete the job.
