John 3:1-4

¹There was a man of the Pharisees named Nicodemus, a ruler of the Jews:

²The same came to Jesus by night, and said to him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him.

³Jesus answered and said to him, Verily, verily, I say to thee, Except a man be born again, he cannot see the kingdom of God.

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