In Damascus the governor under Aretas the king guarded the city of the Damascenes in order to take me: (ASV)
The Greek has "ethnarch", not governor (giving the impression this guy was governing the city). There is no "under" also, just "of".
According to Josephus (Ant., XIX, V, 2-3), the Jews of Alexandria (Egypt) were represented by an ethnarch under Augustus. And the practice was reintroduced by Claudius, and extended for cities with Diaspora Jews. So ethnarch does not have to mean ruler.
2 Corinthians is commonly dated to c. 55. It is unlikely that Aretas was king of Damascus at this time for the following reasons:
1) Dating. The externally known Aretas IV reigned until 40.
I agree for the approximate dating of the 2 Corinthians letters, but the escape from Damascus occurred many years before, according to Galatians & Acts. (According to my calculation, from data within the Pauline epistles and Acts, the year of the escape is 38).
2) Geographical. Aretas IV was king of Nabataea, on the wrong side of Israel from Damascus
What side? Does that matter? I do not think so. Anyway, Damascus was near the northern border of Aretas' controlled territory.
3) Conflict. Aretas IV was in conflict with Rome late in his career.
Aretas IV was in conflict with Rome only from the end of 36 to early 37. There was peace after that.
4) Source. Aretas III did control Damascus in the 1st century BCE establishing a source for error.
5) Significance. It's unlikely that Rome would have granted outside control to a major city like Damascus.
That does not affect my case.
6) Reaction. "Luke", giving the same account, exorcises "Aretas" from the story
"Luke" might not have had accurate or complete information on this episode. Also, "Luke" had the habit to have the Jews causing trouble for Paul.
7) Implausibility. The related action claim of the verse, that Paul escaped via a basket through a window,
is unlikely and if a story is generally unlikely, that makes the individual claims more likely to be in error.
If you are not an experienced climber and not able to rappel down on a fixed rope, then a basket lowered down by a few friends is an excellent idea (at least in antiquity).
Cordially, Bernard
