Albert Barnes Commentary Acts 19:29

"And the city was filled with the confusion: and they rushed with one accord into the theatre, having seized Gaius and Aristarchus, men of Macedonia, Paul`s companions in travel." — Acts 19:29 (ASV)

Confusion. Tumult; disorder.

Gaius. He had lived at Corinth, and had kindly entertained Paul at his house, 1 Corinthians 1:14; Romans 16:23.

Aristarchus. He attended Paul to Rome, and was there a prisoner with him, Colossians 4:10.

With one accord. Tumultuously; or with one mind, or purpose.

Into the theatre. The theatres of the Greeks were not only places for public exhibitions, but also for holding assemblies, and often for courts, elections, etc. The people, therefore, naturally rushed there, as being a suitable place to decide this matter.
