Jesus turned, and saw them following, and said to them, "What are you looking for?" They said to him, "Rabbi" (which is to say, being interpreted, Teacher), "where are you staying?"

 (iv) There is a simpler explanation. Nathanael was brought to Jesus by Philip. Nathanael's name is never mentioned in the other three gospels; and in the Fourth Gospel Bartholomew's name is never mentioned. Now, in the list of the disciples in Matthew 10:3 and Mark 3:18, Philip and Bartholomew come together, as if it was natural and inevitable to connect them. Moreover, Bartholomew is really a second name. It means Son of Tholmai or Ptolemy. Bartholomew must have had another name, a first name; and it is at least possible that Bartholomew and Nathanael are the same person under different names. That certainly fits the facts.
