Matthew Poole and continuators on Numbers 18:1

1 AND the LORD said unto Aaron, Thou, and thy sons, and thy fathers house with thee, shall bear the iniquity of the sanctuary : and thou and thy sons with thee, shall bear the iniquity of your priesthood .

(i. e.) Shall suffer the punishment of all the usurpations or pollutions of the Sanctuary or the holy things by the Levites or any of the people, because you have authority and power from me to keep them all within their bounds, and I expect you use it to that end. Thus the people are in good measure secured against their fears expressed Numb. 17. 12, 13. Also they are informed that Aarons high dignity was attended with great burdens, having not onely his own but the peoples sins to answer for, and therefore, they had no such reason to envy him, as they might think, if the benefits and encumbrances and dangers were equally considered.

(i. e.) Of all the errours committed by your selves or by you permitted in others in things belonging to your Priesthood.
