Ezekiel 44:7, 9

in that ye have brought in foreigners, uncircumcised in heart and uncircumcised in flesh, to be in my sanctuary, to profane it, even my house, when ye offer my bread, the fat and the blood, and they have broken my covenant, to add unto all your abominations.

Thus saith the Lord Jehovah, No foreigner, uncircumcised in heart and uncircumcised in flesh, shall enter into my sanctuary, of any foreigners that are among the children of Israel.
