Joh 3, Verses 1–3English original
There was a man of the Pharisees, named Nicodemus, a ruler of the Jews: The same came to Jesus by night, and said unto 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. Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
(Tr. xi. c. 3) What the ground of his belief was, is plain from what immediately follows: For no one can do these miracles that Thou doest, except God be with him. Nicodemus then was one of the many who believed in His Name, when they saw the signs that He did.
