'Circumcised' in the Bible

Be circumcised to Jehovah, And turn aside the foreskins of your heart, O man of Judah, and ye inhabitants of Jerusalem, Lest My fury go out as fire, and hath burned, And there is none quenching, Because of the evil of your doings.

Behold, the days come, saith the LORD, that I will punish all them which are circumcised with the uncircumcised;

That is, I will punish the Egyptians, the Judeans, the Edomites, the Ammonites, the Moabites, and all the desert people who cut their hair short at the temples. I will do so because none of the people of those nations are really circumcised in the Lord's sight. Moreover, none of the people of Israel are circumcised when it comes to their hearts."
