And the LORD said unto Aaron, Thou and thy sons and thy father's house with thee shall bear the iniquity of the sanctuary: and thou and thy sons with thee shall bear the iniquity of your priesthood. Thou and thy sons - shall bear the iniquity of the sanctuary, etc. - That is, They must be answerable for its legal pollutions, and must make the necessary atonements and expiations.
