Acts 14:12

And they called Barnabas Jupiter
The supreme God; it may be because that Barnabas was the oldest man, of the tallest stature, and largest bulk, and made the best figure; whereas Paul was younger, of a low stature, and mean appearance:

and Paul Mercurius,
because he was the chief speaker; Mercury was the god of eloquence, and the messenger of the gods, and the interpreter of their will ^F18; Paul being chiefly concerned in preaching and speaking to the people, they called him by the name of this God: the Jews had a doctor in their schools, whom they called (Myrbdmh vad) , "the chief of the speakers" ^F19.
