Charles Ellicott Commentary Numbers 16:6

"This do: take you censers, Korah, and all his company;" — Numbers 16:6 (ASV)

Take you censers. —The offering of incense was the exclusive prerogative and the holiest function of the priesthood. The destruction of Nadab and Abihu ought to have served as a warning to Korah and his company not to provoke a similar exhibition of the Divine displeasure.
