“Now when they had passed through Amphipolis and Apollonia, they came to Thessalonica, where was a synagogue of the Jews:”
King James Version (KJV)
17:1 And taking their journey through Amphipolis and Apollonia - St. Luke seems to have been left at Philippi; and to have continued in those parts, travelling from place to place among the Churches, till St. Paul returned thither. For here he leaves off speaking of himself as one of St. Paul's company; neither does he resume that style, till we find them together there, #Acts 20:5|,6. After this he constantly uses it to the end of the history. Amphipolis and Apollonia were cities of Macedonia.
Ac 17:1 Paul at Athens SUMMARY OF ACTS 17: The Journey to Thessalonica. Labors in the Synagogue. A Church Planted. The Jews Stir Up Persecution. Departure to Berea. Journey to Athens. The City Full of Idols. Paul's Evangelistic Labors. Taken to the Areopagus. His Address to the Athenians. The Diverse Results: Some Mock; Some Propose to Hear Again;. Some Are Converted. Passed through Amphipolis . . . came to Thessalonica. They traveled along the great Roman military road, which passed through Macedonia and Greece to Dyrrachium on the Adriatic Sea, and then beginning on the other side at Brundisium, extended to Rome. Amphipolis was about thirty miles, a day's journey, southwest of Philippi; Apollonia about the same distance farther on, and Thessalonica about twenty-eight miles west of Apollonia. Thessalonica was a rich commercial city, the seat of the Roman governor of Macedonia, and is still a city of about 70,000 population, of whom one-third are Jews. Its excellent harbor makes it a coveted object of Austrian diplomacy in the Balkan provinces.
