4Nicodemus says to Him: “How can a man be begotten, being old? He can't enter his mother's womb a second time and be born, can he?”
5Jesus answered: “Most assuredly I say to you, unless someone is begotten by water and Spirit he is not able to enter the kingdom of God.
6That which has been begotten by the flesh is flesh, and that which has been begotten by the Spirit is spirit.
7Do not be perplexed that I said to you, ‘You (pl) need to be begotten from Above.’
