Ezekiel 44:8-12

And you have not taken responsibility for My holy things yourselves, but you have appointed foreigners to take responsibility for My sanctuary.”

‘This is what the Lord God says: “No foreigner uncircumcised in heart and uncircumcised in flesh, of all the foreigners who are among the sons of Israel, shall enter My sanctuary.

But the Levites who went far from Me when Israel went astray, who went astray from Me following their idols, shall suffer the punishment for their wrongdoing.

Yet they shall be ministers in My sanctuary, having oversight at the gates of the house and ministering in the house; they shall slaughter the burnt offering and the sacrifice for the people, and they shall stand before them to minister to them.

Since they ministered to them before their idols and became a stumbling block of wrongdoing to the house of Israel, for that reason I have sworn against them,” declares the Lord God, “that they shall suffer the punishment for their wrongdoing.
