Ezekiel 44:7

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.

Ezekiel 44:9

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.
