Ezekiel 44:9

5 The LORD said to me: “Son of man, pay attention; look carefully with your eyes and listen closely with your ears to everything I tell you concerning all the statutes and laws of the house of the LORD. Take careful note of the entrance to the temple, along with all the exits of the sanctuary.

6 Tell the rebellious house of Israel that this is what the Lord GOD says: ‘I have had enough of all your abominations, O house of Israel.

7 In addition to all your other abominations, you brought in foreigners uncircumcised in both heart and flesh to occupy My sanctuary; you defiled My temple when you offered My food—the fat and the blood; you broke My covenant.

8 And you have not kept charge of My holy things, but have appointed others to keep charge of My sanctuary for you.’

9 This is what the Lord GOD says: No foreigner uncircumcised in heart and flesh may enter My sanctuary—not even a foreigner who lives among the Israelites.

10 Surely the Levites who wandered away from Me when Israel went astray, and who wandered away from Me after their idols, will bear the consequences of their iniquity.

11 Yet they shall be ministers in My sanctuary, having charge of the gates of the temple and ministering there. They shall slaughter the burnt offerings and other sacrifices for the people and stand before them to minister to them.

12 Because they ministered before their idols and became a stumbling block of iniquity to the house of Israel, therefore I swore with an uplifted hand concerning them that they would bear the consequences of their iniquity, declares the Lord GOD.

13 They must not approach Me to serve Me as priests or come near any of My holy things or the most holy things. They will bear the shame of the abominations they have committed.
