Commentaries:
This is an inter-family squabble, mostly an argument among Levites, headed by a grandson of Kohath, Korah. Moses puts the blame squarely on the ones who were in charge. These Levites thought they had been kept out of the good positions. Their job was to take down the Tabernacle, cart it off, and do other physical labors, while Aaron's family got to be priests.
