Parshas Nitzavim

Liyluy Nishmas Elchonon Tzvi ben R' Yisroel Menachem, Zekaini Moiri R' Baruch Moshe Aryeh ben Harav Zev Yehuda, my cousin Zev Yehuda ben Rav Shmuel Mordechai, Avraham ben R' Yitzchok Zev, R' Dovid Meir ben Rav Shmuel...

In Parshas Nitzavim perek chaf tes posuk yud alef Moshe tells Klal Yisroel "L'avricha b'bris Hashem Elokecha uv'alaso asher Hashem Elokecha koreis imcha hayom". " For you to pass into a bris of Hashem your God, and into his oath that Hashem your God forges with you today.

The Yalkut Shimoni explains that throught history there were three brisos (covenants) that Hashem forged with Klal Yisroel. One when they left Mitzrayim, and one in Choreiv, and one now. The reason for the one now says the Yalkut Shimoni, is because the eigel had recently occured and the eirev rav had told Klal Yisroel "Eileh elokecha Yisroel" "This is your god Klal Yisroel", and the previous brisos became batul, therefore Hashem was chozer and re-forged the bris with Klal Yisroel.
The Rosh Yeshiva ztl asks, Why did Hashem need to forge a new bris at this point? Its pashut that the previous brisos were not actually cancelled by Klal Yisroel when they said "eileh elokecha". The Bris that Hashem made with Klal Yisroel is everlasting and can be proven throughout the Torah, so what is the yalkut shimoni saying that the previous brisos where batul?

The Rosh Yeshiva explains that the Bris in Choreiv was obviously not batul and is truly everlasting. The Medrash is just saying what Klal Yisroel felt in their hearts. After Klal Yisroel served the Eigel, they felt in their hearts that The Bris must have been destroyed fbecause of their aveira and therefore Hashem made a new bris with them now.

However the Rosh Yeshiva explains, the matter still seems puzzling. Why did Hashem have to be koireis a new bris, why couldn't he just explain to Klal Yisroel that the old one was still intact?
The Rosh Yeshiva explains that even if Hashem would have just told Klal Yisroel that the previous bris was intact, Klal Yisroel would still feel in their hearts that is was null and void because the heart and mind although mere inches away from each other are really worlds apart.

Klal Yisroel could have known in their seichel that the bris was still there even after the Eigel just as it was there before, but in their hearts they would not have fully believed it. They knew, but they did not really know. Hashem needed to be koireis a brand new bris so that Klal Yisroel would truly know deep within them that Hashem still loved them and the bris was still there and would be there forever.
