Expositor's Bible Commentary Commentary Acts 21:6

"and we went on board the ship, but they returned home again." — Acts 21:6 (ASV)

After a scene reminiscent of the parting with the Ephesian elders (cf. 20:36– 37), Paul and his companions sailed from Tyre. The ship went on to Ptolemais, another ancient Phoenician seaport south of Tyre. There it made harbor for a day, undoubtedly again to unload cargo. Once more Paul met with the believers of the city. Probably Christianity at Ptolemais also stemmed from the witness of the Hellenistic Christians (cf. 11:19).
