Ezekiel 44:10-14

“ ‘But the Levites who stopped obeying me when Israel left me and who followed their idols must be punished for their sin. These Levites are to be servants in my Holy Place. They may guard the gates of the Temple and serve in the Temple area. They may kill the animals for the burnt offering and the sacrifices for the people. They may stand before the people to serve them. But these Levites helped the people worship their idols and caused the people of Israel to fall, so I make this promise: They will be punished for their sin, says the Lord GOD. They will not come near me to serve as priests, nor will they come near any of my holy things or the most holy offerings. But they will be made ashamed of the things they did that I hate. I will put them in charge of taking care of the Temple area, all the work that must be done in it.
