For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: For he is not a Jew - A genuine member of the Church of God, who has only an outward profession.
Neither is that circumcision - Circumcision is a rite which represents a spiritual thing, viz. the change and purification of the heart, as may be seen, Jeremiah 4:4, Jeremiah 4:6, Jeremiah 4:10; Jeremiah 9:26; Ezekiel 44:7, Ezekiel 44:9.
