Ezekiel 44:10-11, 14

“And the Levites who went far from Me, when Israel went astray, who strayed away from Me after their idols, they shall bear their iniquity. Yet they shall be ministers in My sanctuary, as gatekeepers of the house and ministers of the house; they shall slay the burnt offering and the sacrifice for the people, and they shall stand before them to minister to them.

Nevertheless I will make them keep charge of the temple, for all its work, and for all that has to be done in it.
