'Uncircumcised In Heart' in the Bible

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

Thus says lord LORD: No foreigner, uncircumcised in heart and uncircumcised in flesh, shall enter into my sanctuary, of any foreigners that are among the sons of Israel.

Ye stiff-necked and uncircumcised in heart and ears, ye do always resist the Holy Spirit. As your fathers, ye also.
