20 Now there were some Greeks amongst those going up so that they might worship in the feast.
21 These men then came to Philip, the one from Bethsaida in Galilee, and they asked him, saying: “Sir, we want to see Jesus.”.
22 Philip came to Andrew and told him; Andrew and Philip went to Jesus and told Him.
In vast crowds there may be people from many different countries and races. All come together in a common cause. Quite often it will be a major sporting event that draws all peoples together. The Olympic Games is one event that stands out from all the other events, because people from all nations on earth compete in them, and every nation supports their own country.
In a similar manner there would have been many people from different nations who were attending the Feast of Passover. We have already seen that at the Feast of Pentecost seven weeks later there were people from all over the known world. As said before, many of these would have already been in Jerusalem for the Passover Feast and then stayed on for Pentecost.
Amongst the crowds welcoming Jesus into Jerusalem were some Greeks.
It would appear that these Greeks were not Jewish Greeks, but Gentile Greeks who had turned from their religions to embrace Judaism, and to worship the One God.
