Ezekiel 44:7-9

44:7 When you bring foreigners, those uncircumcised in heart and in flesh, into my sanctuary, you desecrate it – even my house – when you offer my food, the fat and the blood. You have broken my covenant by all your abominable practices. 44:8 You have not kept charge of my holy things, but you have assigned foreigners to keep charge of my sanctuary for you. 44:9 This is what the sovereign Lord says: No foreigner, who is uncircumcised in heart and flesh among all the foreigners who are among the people of Israel, will enter into my sanctuary.
