New Revised Standard Version, Anglicised Catholic Edition

² He came to Jesus^[a] by night and said to him, ‘Rabbi, we know that you are a teacher who has come from God; for no one can do these signs that you do apart from the presence of God.’ ³ Jesus answered him, ‘Very truly, I tell you, no one can see the kingdom of God without being born from above.’^{[b] 4} Nicodemus said to him, ‘How can anyone be born after having grown old? Can one enter a second time into the mother’s womb and be born?’
