Albert Barnes Commentary Acts 19:31

"And certain also of the Asiarchs, being his friends, sent unto him and besought him not to adventure himself into the theatre." — Acts 19:31 (ASV)

Certain of the chief of Asia. twn asiarcwn. Of the Asiarchs. These were persons who presided over sacred things and over the public games.

It was their business to see that the proper services of religion were observed, and that proper honour was rendered to the Roman emperor in the public festivals, at the games, etc. They were annually elected, and their election was confirmed at Rome before it was valid.

They held a common council at the principal city within their province, as at Ephesus, Smyrna, Sardis, etc., to consult and deliberate about the interests committed to their charge in their various provinces—Kuinoel and Schleusner. Probably they were assembled on such an occasion at that time; and during their stay there, they had heard Paul preach and were friendly to his views and doctrines.

Which were his friends. It does not appear from this that they were Christian converts; but they probably had feelings of respect towards him, and were disposed to defend him and his cause. Perhaps, also, there might have existed a present acquaintance and attachment.

Would not adventure. Would not risk his life in the tumult, and under the excited feelings of the multitude.

The term “chief” can be understood as “chief magistrates.” Compare Acts 21:12, which mentions desiring him.
