Numbers 16:6

Censers. It was not lawful for the Levites to offer incense: but they had prepared for themselves the ensigns of the priestly power, and Moses permits them to try their success. (Haydock) --- They might have brought the censers, or broad plates, bowls, or vials, (Apocalypse v. 8,) out of Egypt, where every family offers incense to their domestic gods and sacred animals. In Sicily and Greece they were also very common, as well as at Babylon; where married people always purified themselves with the smoke of incense. (Herodotus, i. 197.)
