When Jesus had finished instructing his twelve disciples, he went on from there to teach and preach in their cities.
Matthew 11:1

Yeshua was not accepted in his own home town and he knew his disciples would not be accepted in theirs either. He sent them to go preach the Gospel in the rest of the Jewish towns of Judea and Samaria, while he stayed behind and taught people in the home towns of the disciples. People haven't changed much since then.
