Acts 18:12

This Gallio was brother to the great Seneca, Nero's preceptor, as that author himself assures us. (Præf. lib. v. Quæs. Natur.) He was called Annæus Novatus, but took the name of Gallio by adoption, and was made proconsul by his brother's interest, whose honours and disgraces he equally participated. Being condemned to death by Nero, he laid violent hands upon himself. It is probable St. Paul became acquainted with Seneca. St. Jerome and St. Augustine say, many letters passed between them, which are not now extant. (Tirinus) See also Eusebius. An. Christi 66. [The year A.D. 66.]

Ver 17. Beat him. It is uncertain whether the Jews themselves beat Sosthenes, being vexed at him, for not managing well the cause; or whether he was struck by the attendants of the proconsul, to force him away, when he would not desist, nor retire. See the Analysis, dissert. xxxv. (Witham)
