Moses
Numbers 16:6ESV·traditional attribution

Do this: take censers, Korah and all his company;

Matthew Henry Presbyterian @wholebiblehenry

Here is, I. An account of the rebels, who and what they were, not, as formerly, the mixed multitude and the dregs of the people, who are therefore never named, but men of distinction and quality, that made a figure. Korah was the ring-leader: he formed and headed the faction; therefore it is called the gainsaying of Korah, Jde 1:11.

Commenting on Numbers 16:1-11

John Gill Reformed Baptist @doctorgill

This do, take you censers,.... Vessels to put incense in to offer, which was the business of the priests: Korah, and all his company; the two hundred fifty princes that were with him, for so many we read took censers, and offered incense, Num 16:18.

Jamieson-Fausset-Brown Reformed @jfbcommentary

Take your censers, Korah, and all his company, &c.--that is, since you aspire to the priesthood, then go, perform the highest function of the office--that of offering incense; and if you are accepted well. How magnanimous the conduct of Moses, who was now as willing that God's people should be priests, as formerly that they should be prophets (Num 11:29).
