Bible Verses About Uncircumcision: Uncircumcised heart

Thou shalt die the death of the uncircumcised by the hand of strangers: for I have spoken it, saith the Lord God.

In that you have brought in strangers uncircumcised in heart, and uncircumcised in flesh, to be in my sanctuary, and to defile my house: and you offer my bread, the fat, and the blood: and you have broken my covenant by all your wicked doings.

Thus saith the Lord God: No stranger uncircumcised in heart, and uncircumcised in flesh, shall enter into my sanctuary, no stranger that is in the midst of the children of Israel.
