'Uncircumcised' in the Bible

To whom shall I speak and testify, that they may hear? behold, their ear is uncircumcised, and they cannot hearken: behold, the word of Jehovah is become unto them a reproach; they have no delight in it.

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.
