acts 13:14 But when they departed from Perga, they came to Antioch in Pisidia, and went into the synagogue on the sabbath day, and sat down. - Free Bible Online

      14. departed from Perga--apparently without making any stay or doing any work: compare the different language of Ac 14:25, and see immediately below.
      came to Antioch in Pisidia--usually so called, to distinguish it from Antioch in Syria, from which they had started, though it actually lies in Phrygia, and almost due north from Perga. It was a long journey, and as it lay almost entirely through rugged mountain passes, while "rivers burst out at the base of huge cliffs, or dash down wildly through narrow ravines," it must have been a perilous one. The whole region was, and to this day is, infested by robbers, as ancient history and modern travels abundantly attest; and there can be but little doubt that to this very journey Paul many years after alludes, when he speaks amidst his "journeyings often," of his "perils of rivers" (as the word is), and his "perils of robbers" (2Co 11:26). If this journey were taken in May--and earlier than that the passes would have been blocked up with snow--it would account for their not staying at Perga, whose hot streets are then deserted; "men, women, and children, flocks, herds, camels, and asses, all ascending at the beginning of the hot season from the plains to the cool basin-like hollows on the mountains, moving in the same direction with our missionaries" [HOWSON].
