John
King James Version (KJV)

“Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.”
King James Version (KJV)
1:13 Who were born - Who became the sons of God, not of blood - Not by descent from Abraham, nor by the will of the flesh - By natural generation, nor by the will of man - Adopting them, but of God - By his Spirit.
Joh 1:13 Who were born, not of blood, nor of the will of the flesh. The Jews prided themselves on being Abraham's children, and trusted in their blood for salvation. To be a son of God is not a fleshly birth at all, but the spirit of the subject is "born of God". The Savior explains the birth more particularly, in Joh 3:1-8.
