Ezekiel 44:9-14

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

10But the Levites who went far away from Me when Israel went astray, who went astray from Me after their idols, they shall bear the punishment for their sin and guilt.

11Yet they shall minister in My sanctuary, having oversight [as guards] at the gates of the temple and ministering in the temple. They shall slaughter the burnt offering and the sacrifice for the people, and they shall stand before them to minister to them.

12Because the priests ministered to them before their idols and became a stumbling block of sin to the house of Israel, therefore I have lifted up My hand and have sworn [an oath] against them,” says the Lord God, “that they shall bear the punishment for their sin and guilt.

13And they shall not come near to Me to serve as priests to Me, nor come near to any of My holy things, to the things that are most holy; but they shall bear their shame and their disgrace and [the consequences of] their repulsive acts which they have committed.

14Yet I will appoint them as caretakers of the temple, for all its service and for all that shall be done in it.
