Greek was an important language in the eastern Roman world. Jewish communities in Palestine lived alongside this Greek-speaking culture. Some Jews used Greek themselves, although ability varied from person to person.
Greek influence had been present in the region long before the lifetime of Jesus.
By the first century, Greek was important in the wider eastern Roman world.
Jewish life therefore developed in regular contact with Greek language and culture.
Greek spread widely after the conquests of Alexander the Great.
Roman rule did not remove its importance in the eastern Mediterranean.
Greek continued to serve as an important language of communication across the region.
How often a Jewish person used Greek depended on circumstances.
Contact with Greek could increase through commerce or interaction with the wider Roman world.
Other people may have had little reason to use it regularly.
Greek inscriptions provide direct evidence for the language in Roman Palestine.
Coins and other written materials also show its public presence.
Such evidence does not mean that every inhabitant spoke Greek fluently.
Many Jewish texts from the wider ancient world were written in Greek.
The Greek translation of the Hebrew Scriptures had already been in use for generations before the time of Jesus.
By the first century, Jewish Scripture existed in Greek as well as in Hebrew.
This allowed biblical texts to circulate among Jewish communities where Greek was widely used.
The books of the New Testament were written in Greek.
That allowed the message about Jesus to circulate widely through the eastern Roman world.
The language of the written Gospels should not be confused with the question of which language Jesus used in every conversation.
Greek had an important place in Roman Palestine and throughout the eastern Roman Empire.
Some Jews used Greek, but ability and frequency of use varied.
We should not assume either that Jesus knew no Greek or that He routinely conducted His teaching in Greek.
The surviving evidence does not allow us to settle every question about His personal language use.
Greek helps connect the Jewish setting of Jesus with the larger Roman world.
It also helps explain how the written New Testament could carry the story of Jesus far beyond Judaea and Galilee.
