John 3:5 WEB

³  Jesus answered him, 'Most assuredly, I tell you, unless one is born anew,{The word translated 'anew' here and in John 3:7 (anothen) also means 'again' and 'from above'.} he can't see the Kingdom of God.'

⁴  Nicodemus said to him, 'How can a man be born when he is old? Can he enter a second time into his mother's womb, and be born?'

⁵  Jesus answered, 'Most assuredly I tell you, unless one is born of water and spirit, he can't enter into the Kingdom of God!

⁶  That which is born of the flesh is flesh. That which is born of the Spirit is spirit.

⁷  Don't marvel that I said to you, 'You must be born anew.'
