John Wesley on Acts 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.
