Ezekiel 44:7, 9

You brought foreigners into my Holy Place who were not circumcised in the flesh and had not given themselves to serving me. You dishonored my Temple when you offered me food, fat, and blood. You broke my agreement by all the things you did that I hate.

This is what the Lord GOD says: Foreigners who are not circumcised in flesh and who do not give themselves to serving me may not enter my Temple. Not even a foreigner living among the people of Israel may enter.
