Ezekiel 44:10-16

10And the men of the tribe of Levi who abandoned me when Israel strayed away from me to worship idols must bear the consequences of their unfaithfulness.

11They may still be Temple guards and gatekeepers, and they may slaughter the animals brought for burnt offerings and be present to help the people.

12But they encouraged my people to worship idols, causing Israel to fall into deep sin. So I have taken a solemn oath that they must bear the consequences for their sins, says the Sovereign Lord.

13They may not approach me to minister as priests. They may not touch any of my holy things or the holy offerings, for they must bear the shame of all the detestable sins they have committed.

14They are to serve as the Temple caretakers, taking charge of the maintenance work and performing general duties.

15“However, the Levitical priests of the family of Zadok continued to minister faithfully in the Temple when Israel abandoned me for idols. These men will serve as my ministers. They will stand in my presence and offer the fat and blood of the sacrifices, says the Sovereign Lord.

16They alone will enter my sanctuary and approach my table to serve me. They will fulfill all my requirements.
