A place built for dramatic and other public entertainments, and for meetings of the people. At the uproar at Ephesus they rushed into the theater (Acts 19:29,3129And the whole city was filled with confusion: and having caught Gaius and Aristarchus, men of Macedonia, Paul's companions in travel, they rushed with one accord into the theatre. (Acts 19:29)
31And certain of the chief of Asia, which were his friends, sent unto him, desiring him that he would not adventure himself into the theatre. (Acts 19:31)). The word is θέατρον, and is translated “spectacle” in 1 Corinthians 4:99For I think that God hath set forth us the apostles last, as it were appointed to death: for we are made a spectacle unto the world, and to angels, and to men. (1 Corinthians 4:9); the apostles were gazed upon both by angels and by men.
