“For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:”
King James Version (KJV)
2:28 For he is not a Jew - In the most important sense, that is, one of God's beloved people. Who is one in outward show only; neither is that the true, acceptable circumcision, which is apparent in the flesh.
Ro 2:28 For he is not a Jew. He is not a Jew, in the religious sense of one of God's chosen people, who is one outwardly alone. Neither [is that] circumcision, the true circumcision, that which makes one a member of God's covenanted church, "which is outward in the flesh".
