Jamieson, Fausset and Brown on Numbers 18:1

CHAPTER 18

Nu 18:1-7. The Charge of the Priests and Levites.

1. the Lord said unto Aaron, Thou and thy sons and thy father's house with thee shall bear the iniquity of the sanctuary--Security is here given to the people from the fears expressed (Nu 17:12), by the responsibility of attending to all sacred things being devolved upon the priesthood, together with the penalties incurred through neglect; and thus the solemn responsibilities annexed to their high dignity, of having to answer not only for their own sins, but also for the sins of the people, were calculated in a great measure to remove all feeling of envy at the elevation of Aaron's family, when the honor was weighed in the balance with its burdens and dangers.
