'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, who dwell in the wilderness; for all the nations are uncircumcised, and all the house of Israel are uncircumcised in heart."

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

"Thus says the Lord GOD, 'No foreigner, uncircumcised in heart and uncircumcised in flesh, shall enter into my sanctuary, of any foreigners who are among the children of Israel.

"You stiff-necked and uncircumcised in heart and ears, you always resist the Holy Spirit. As your fathers did, so you do.
