John 3:4-6

Young's Literal Translation

⁴ Nicodemus saith unto him, `How is a man able to be born, being old? is he able into the womb of his mother a second time to enter, and to be born?'

⁵ Jesus answered, `Verily, verily, I say to thee, If any one may not be born of water, and the Spirit, he is not able to enter into the reign of God;

⁶ that which hath been born of the flesh is flesh, and that which hath been born of the Spirit is spirit.
