I heard that the great Rebbe Rav Menachem Mendel of Kotzk ZY"A, said once on Shabbos Kodesh Parshas "Vayiekach Korach” As follows.

The Parshischer Rebbe interpreted "Vayiekach Korach and Korach took". Korach wanted to take by himself; therefore, it was not appropriate. [It is also possible that his Kavonoh (intention) was not LiSheim Shomayim (for the sake of Hashem), rather for his own respect. - Likutim Chadoshim].
