Chasidut על במדבר 16:13

The reason why Datan and Aviram added a complaint against ‎Moses that Korach had not mentioned, when they said: “you also ‎did not bring us to a land of milk and honey,” (Numbers 16,13) was that ‎Korach was a member of the tribe of Levi that had not been ‎condemned to die in the desert. Korach therefore could not have ‎leveled this accusation at Moses. [According to a view expressed ‎in Baba batra 121. Ed.]‎
