'Uncircumcised In Heart' in the Bible

Egypt, and Judah, and Edom, and the children of Ammon, and Moab, and all that have the corners of their hair cut off, that dwell in the wilderness; for all the nations are uncircumcised, and all the house of Israel are uncircumcised in heart.

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.

Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Spirit: as your fathers did, so do ye.
