Adam Clarke on Acts 18:14

Paul was now about to open his mouth - He was about to enter on his defense; but Gallio, perceiving that the prosecution was through envy and malice, would not put Paul to any farther trouble, but determined the matter as follows.

If it were a matter of wrong - Αδικημα, Of injustice; any thing contrary to the rights of the subject.

Or wicked lewdness - Ῥᾳδιουργημα πονηρον, Destructive mischief. (See the note on Act 13:10, where the word is explained.) Something by which the subject is grievously wronged; were it any crime against society or against the state.

Reason would that I should bear with you - Κατα λογον αν ηνεσχομην ὑμων, According to reason, or the merit of the case, I should patiently hear you.
