The only sea the Hebrews knew (Num. 13: 29) and feared (Ps. 104: 25; Rev. 21: 1); they were content to leave maritime trade in the hands of Phoenicians (1 Kgs. 9: 27). In NT times the Romans controlled the sea and the port of Caesarea was used by ships which conveyed cargoes to Rome, and Paul embarked there (Acts 9: 30). Paul's main activities were in places on the Aegean Sea, a NW inlet of the Mediterranean.
