John Calvin on Acts 19:30-32

30. And when Paul would. We may see that Paul’s constancy was coupled with modesty. When as he might well have kept himself out of sight, of his own accord was he prepared to put himself in hazard. And yet he doth not refuse to follow their counsel, who knew the state of matters better than he. If he had not been kept back, that which he determined to do could not have been imputed to rashness. There was no sedition raised through his fault. Why should he not venture his life, especially seeing that he did not despair of better success? But when the brethren, and such friends as were more skillful, dissuade him, his modesty is worthy to be commended, in that he doth not stand stoutly in his purpose.
