Musar su Numeri 17:2

To return to the matter of the two hundred and fifty men: Their sin consisted neither of an act of insurrection, nor of belittling the honor of G–d or of Moses his prophet. On the contrary, they strove to be accorded the kind of honour and glory that is traditionally reserved for the sages once they enter the World to Come. They endeavoured to come close to G–d and died while coming too close to G–d prematurely. Since incense is a symbol of a close relationship with G–d, their censers became sanctified, not like those of Korach whose incense was equivalent to idol worship. We can read this out of the verses which do not tell us that G–d had commanded to take "the censers and convert them into a covering for the altar." The Torah stresses that only "the censers of those who had sinned with their souls," i.e. the two hundred and fifty men, should be used. Of those censers it had been said כי קדשו, "for they had become sanctified" [they had become holy vessels, fit only for usage in a holy setting].
