Easton's Bible Dictionary (1897)
The people is victor, a Pharisee and a member of the Sanhedrin. ” He is next met with in the Sanhedrin (7:50-52), where he protested against the course they were taking in plotting against Christ. Once more he is mentioned as taking part in the preparation for the anointing and burial of the body of Christ (John 19:39). We hear nothing more of him. There can be little doubt that he became a true disciple.
Smith's Bible Dictionary (1863)
(conqueror of the people), a Pharisee, a ruler of the Jews and a teacher of Israel, (John 3:1,10) whose secret visit to our Lord was the occasion of the discourse recorded only by St. John. In Nicodemus a noble candor and a simple love of truth shine out in the midst of hesitation and fear of man. He finally became a follower of Christ, and came with Joseph of Arimathaea to take down and embalm the body of Jesus.
Hastings' Dictionary of the Bible (1898) & Schaff's Bible Dictionary
NICODE'MUS (victor of the people), a ruler of the Jews, and a distinguished member of the sect of the Pharisees, whose conversation with the Messiah, as recorded in John 3, reveals one of the grand doctrines of the Christian system - viz., regeneration by the Spirit of God. On this occasion he betrayed himself as a timid disciple, or as one just seeking after the truth, for he came to Christ under the cover of darkness.
Later he defends Christ against the bitter injustice of the Pharisees, John 7:50, and finally he appears as a professed follower, helping in the sepulture of the crucified Lord. John 19:89.
