John 1:13 - Clarke's commentary and critical notes on the Bible

Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. Which were born, not of blood - Who were regenerated, ουκ εξ αἱματων, not of bloods - the union of father and mother, or of a distinguished or illustrious ancestry; for the Hebrew language makes use of the plural to point out the dignity or excellence of a thing: and probably by this the evangelist intended to show his countrymen, that having Abraham and Sarah for their parents would not entitle them to the blessings of the new covenant; as no man could lay claim to them, but in consequence of being born of God; therefore, neither the will of the flesh - any thing that the corrupt heart of man could purpose or determine in its own behalf; nor the will of man - any thing that another may be disposed to do in our behalf, can avail here; this new birth must come through the will of God - through; his own unlimited power and boundless mercy, prescribing salvation by Christ Jesus alone. It has been already observed that the Jews required circumcision, baptism, and sacrifice, in order to make a proselyte. They allow that the Israelites had in Egypt cast off circumcision, and were consequently out of the covenant; but at length they were circumcised, and they mingled the blood of circumcision with the blood of the paschal lamb, and from this union of bloods they were again made the children of God. See Lightfoot. This was the only way by which the Jews could be made the sons of God; but the evangelist shows them that, under the Gospel dispensation, no person could become a child of God, but by being spiritually regenerated.
