Ezekiel 44:11, 15

They may serve in my sanctuary, having charge of the gates of the temple and serving in it; they may slaughter the burnt offerings and sacrifices for the people and stand before the people and serve them.

“ ‘But the Levitical priests, who are descendants of Zadok and who guarded my sanctuary when the Israelites went astray from me, are to come near to minister before me; they are to stand before me to offer sacrifices of fat and blood, declares the Sovereign LORD.
