Numbers 16:17

And take every man his censer, and put incense therein,.... Which they were to bring with them the next day from their own tents; and these might be censers which they had in their several families, and which they had used in them before the order of priesthood was set up in Aaron's family, and limited to that; or they might be a sort of chafing dishes, or vessels like censers, and would serve the present purpose; they were ordered to put fire into them, that was to be taken from the altar of burnt offering; for strange fire might not be used;

and bring ye before the Lord every man his censer, two hundred and fifty censers: according to the number of the men that were gathered with Korah:

thou also, and Aaron, each [of you] his censer; Korah and Aaron were to bring each their censers, between whom lay the contest concerning the high priesthood; which was to be determined by their offering incense before the Lord, and by his approbation or disapprobation of it.
