{Passing through} (dielthontes). It is not clear why Paul
and Barnabas left Perga so soon nor why they went to Antioch in
Pisidia. Ramsay suggests malaria that spurred them on to the
hills after the desertion of John Mark. They preached at Perga on
the return ( 14:25 ) and apparently hurried away now. Farrar
thinks that the hot weather had driven the population to the
hills. At any rate it is not difficult to imagine the perils of
this climb over the rough mountain way from Perga to Pisidian
Antioch to which Paul apparently refers in  2Co 11:26 . {Sat
down} (ekathisan). Ingressive aorist active indicative, took
their seats as visiting Jews, possibly in the seats of the rabbis
(J. Lightfoot). Whether they expected to be called on or not,
they were given the opportunity as prominent visitors. The
Pisidian Antioch was really in Phrygia, but towards Pisidia to
distinguish it from Antioch on the Maeander (Ramsay, _Church in
the Roman Empire_, p. 25). It was a colony like Philippi and so a
free city. If Paul is referring to South Galatia and not North
Galatia in  Ga 4:13  when he says that his preaching in Galatia
at first was due to illness, then it was probably here at
Pisidian Antioch. What it was we have no means of knowing, though
it was a temptation in his flesh to them so severe that they were
willing to pluck out their eyes for him ( Ga 4:14f. ). Opthalmia,
malaria, epilepsy have all been suggested as this stake in the
flesh ( 2Co 12:7 ). But Paul was able to preach with power
whatever his actual physical condition was.
