John 8:57 has the Jews say that Jesus was not yet 50 when he came to Jerusalem. (They mock him for claiming to have seen Abraham). If that is the case, then Jesus was probably close enough, but not yet 50; maybe in his late fourties?
That is of importance, because the Gospels constantly talk about this generation as the target of the words of Jesus. And while Paul portrays himself as the apostle to the Gentiles, nothing in the Gospels mentions him; there is though a reference to a mission to the entire world, but it surely reads like a late addition.
