Romans 2:28

Verse 28. Nor is that circumcision, which is outwardly in the flesh. Saint Paul distinguisheth two sorts of circumcision; that which is made in the flesh, according to the letter of the law, which is an outward circumcision; and a more necessary circumcision of the heart, and of the spirit, by which a man’s interior is reformed, and by which his vices and disorders are cut off. The first circumcision would never avail a man any thing without the second. Witham.
