Answer:
According to the New Testament of the Bible, Nicodemus was a Pharisee and a member of the Jewish ruling council known as the Sanhedrin. He came to Jesus by night seeking to understand his teachings. In the Gospel of John, Nicodemus is depicted as a seeker of truth.
Nicodemus is not explicitly mentioned as being a teacher to anyone in the biblical texts. Instead, he is primarily known for his interaction with Jesus, particularly their conversation about being "born again" (John 3:1-21).
If you have a specific context or source in mind where Nicodemus is described as a teacher, please provide more information so I can address it accurately.
