Acts 17:13-15

But when the Jews of Thessalonica learned that the word of God [concerning eternal salvation through faith in Christ] had also been preached by Paul at Berea, they came there too, agitating and disturbing the crowds. So at that time the brothers immediately sent Paul away to go as far as the sea; but Silas and Timothy remained there [at Berea]. Those who escorted Paul brought him to Athens; and [after] receiving instructions [from Paul] for Silas and Timothy to join him as soon as possible, they left.
