Ezekiel 44:5-9

5Adonai said to me, “Son of man, set your heart, behold with your eyes and hear with your ears all that I say to you concerning all the ordinances of Adonai’s House and all its laws. Set your heart to the entrance of the House, with all exits of the Sanctuary.

6Say to the rebellious, to the house of Israel, thus says Adonai Elohim: ‘Enough of your abominations, house of Israel!

7You brought in foreigners, uncircumcised in heart and uncircumcised in flesh, to be in My Sanctuary, to profane it—My House—when you offer My bread, the fat and the blood. They have broken My covenant, to add to all your abominations.

8You have not kept charge of My holy things, but you have set keepers of My service in My Sanctuary to please yourselves.’”

9Thus says Adonai Elohim: “No foreigner, uncircumcised in heart and uncircumcised in flesh, may enter My Sanctuary, not any foreigner who is among Bnei-Yisrael.
