One of the two who heard John, and followed him, was Andrew, Simon Peter's brother.

 The answer of John's disciples was that they wished to know where Jesus stayed. They called him Rabbi ( G4461) ; that is a Hebrew word ( H7227) which literally means My great one. It was the title of respect given by students and seekers after knowledge to their teachers and to wise men. John, the evangelist, was writing for Greeks. He knew they would not recognize that Hebrew word, so he translated it for them by the Greek word didaskalos ( G1320) , teacher. It was not mere curiosity which made these two ask this question. What they meant was that they did not wish to speak to Jesus only on the road, in the passing, as chance acquaintances might stop and exchange a few words. They wished to linger long with him and talk out their problems and their troubles. The man who would be Jesus' disciple can never be satisfied with a passing word. He wants to meet Jesus, not as an acquaintance in the passing, but as a friend in his own house.
