Ezekiel 44:12

8You have not performed the duty of my holy things; but you have set performers of my duty in my sanctuary for yourselves.”

9The Lord GOD says, “No foreigner, uncircumcised in heart and uncircumcised in flesh, shall enter into my sanctuary, of any foreigners who are among the children of Israel.

10“‘“But the Levites who went far from me when Israel went astray, who went astray from me after their idols, they will bear their iniquity.

11Yet they shall be ministers in my sanctuary, having oversight at the gates of the house, and ministering in the house. They shall kill the burnt offering and the sacrifice for the people, and they shall stand before them to minister to them.

12Because they ministered to them before their idols, and became a stumbling block of iniquity to the house of Israel, therefore I have lifted up my hand against them,” says the Lord GOD, “and they will bear their iniquity.

13They shall not come near to me, to execute the office of priest to me, nor to come near to any of my holy things, to the things that are most holy; but they will bear their shame and their abominations which they have committed.

14Yet I will make them performers of the duty of the house, for all its service and for all that will be done therein.

15“‘“But the Levitical priests, the sons of Zadok, who performed the duty of my sanctuary when the children of Israel went astray from me, shall come near to me to minister to me. They shall stand before me to offer to me the fat and the blood,” says the Lord GOD.

16“They shall enter into my sanctuary, and they shall come near to my table, to minister to me, and they shall keep my instruction.
