Acts 19:38

“Wherefore if Demetrius, and the craftsmen which are with him, etc.] Who were the ringleaders and encouragers of this tumult: have a matter against any man; any accusation, or charge, any crime to accuse him of, and charge him with: the law is open; or court days are kept; there are certain times fixed for the hearing and trying of causes, where and when such an affair should be regularly brought; and not use such disorderly methods, and throw a city into confusion, and break the peace as these men had done: the Syriac version renders it, “they are artificers”; that is, Demetrius and the craftsmen with him; they are tradesmen, and it does not belong to them, nor should they take upon…”

“if Demetrius have a matter--of complaint. against any man, the law is open--rather, "the court days are being held." and there are deputies--literally "proconsuls" (see on Act 13:7); that is, probably, the proconsul and his council, as a court of appeal.”

“Have a matter against any man - Have a complaint of injury; if injustice has been done them by anyone. The law is open - See the margin. Ἀγόραιοι Agoraioi ἄγονται agontai, that is, ἡμέραι hēmerai. There are court-days; days which are open, or appointed for judicial trials, where such matters can be determined in a proper manner. Perhaps the courts were then held, and the matter might be immediately determined. And there are deputies - Roman proconsuls. See the notes on Acts 13:7. The cause might be brought before them with the certainty that it would be heard and decided. The Syriac reads this in the singular number “Lo, the proconsul is in the city.” Let them implead one another -…”

“There are proconsuls - One in every province. There was one at Ephesus. Acts 19:39”

“Demetrius: Act 19:24 have: Act 18:14; Deu 17:8; Co1 6:1 the law is open: or, the court-days are kept Acts 19:39”
