Acts 18:24

‘Now a certain Jew named Apollos, an Alexandrian by race, an eloquent man, came to Ephesus, and he was mighty in the scriptures.'

Apollos was an Alexandrian from Egypt, which probably means that he interpreted the Scriptures more allegorically than would be done in Palestine. Alexandria had a large Jewish population and was heavily influenced by the Jewish philosopher Philo. He was also very eloquent, and above all very knowledgeable about, and effective in teaching, the Scriptures.
