How many languages did Paul of Tarsus speak?

It's impossible to say for sure how many languages Paul of Tarsus spoke. However, based on his writings and travels, we can deduce that he was likely fluent in at least three languages:

* Hebrew: This was his native language, spoken in the Jewish community in Tarsus.

* Greek: The common language of the Roman Empire and the language in which Paul wrote his epistles.

* Aramaic: A language widely spoken in the Levant, including Judea, where Paul lived for a time.

There is also speculation that Paul may have known some Latin, the language of the Roman administration, due to his Roman citizenship.

However, we lack definitive proof of his fluency in any language beyond Hebrew, Greek, and Aramaic.
