Berea

a city of Macedonia to which Paul with Silas and Timotheus went when persecuted at Thessalonica (Acts 17:10; 17:13), and from which also he was compelled to withdraw, when he fled to the sea-coast and thence sailed to Athens (Acts 17:14; 17:15). Sopater, one of Paul's companions belonged to this city, and his conversion probably took place at this time (Acts 20:4). It is now called Verria.
