Bible Verses About Uncircumcision: Uncircumcised heart

You shall die the death of the uncircumcised by the hand of strangers: for I have spoken it, says the Lord GOD.

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 they 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.
