Parshas Devarim: Rav Itzele Volozhin - Moshe Rebukes Bnei Yisroel For Pushing And Shoving
When Moshe before his death gives mussar to Bnei Yisrael for all they have done wrong in the Midbar, he includes the episode of the Meraglim.  "Vatikrivun Eilai Kulchem; Everyone approached me to send Miraglim to Eretz Yisrael." (Devarim 1:21)  Rashi says that they came "B'arvuvia" in a charging crowd, with the young pushing the old and the old pushing the leaders.  In the last moments of Moshe's life where he rebukes Bnei Yisrael for major history changing aveiros, was it necessary to nitpick and complain about the pushing?

The Netziv brings from his father-in-law, Rav Itzele Volozhin, that for the Chait of the Meraglim Bnei Yisrael claimed that they had the best of intentions.  It was only after that, that the Meraglim themselves ruined everything with their evil intentions.  Moshe tells them that it is clear from the way they came pushing and shoving that their intentions were not kosher and the end will turn sour.  People who are running L'Shem Shamayim do not push and shove along the way.  For good things, you proceed with Derech Eretz.
