Who ought to have been here; the Jews of Asia, who had caused all this stir, having seen Trophimus with Paul in the streets of Jerusalem, and maliciously presuming that he had brought him into the temple with him. Now these were the only proper witnesses, who might therefore be now absent, because they could testify nothing to the purpose, and when they thought seriously upon it, their consciences might accuse them for the clamour they had made against the apostle, Acts 21:28. As for the other Jews, they could only testify, by hearsay, which is not sufficient.
