“And when Gallio was the deputy of Achaia, the Jews made insurrection with one accord against Paul, and brought him to the judgment seat,”
King James Version (KJV)
18:12 When Gallio was proconsul of Achaia - Of which Corinth was the chief city. This Gallio, the brother of the famous Seneca, is much commended both by him and by other writers, for the sweetness and generosity of his temper, and easiness of his behaviour. Yet one thing he lacked! But he knew it not and had no concern about it.
Ac 18:12 When Gallio was the deputy of Achaia. "Proconsul" in the Revised Version, as it should be. The province of Achaia had been transferred by Claudius to the government of the senate, and the governors of senatorial provinces were proconsuls, which is the meaning of the Greek term "anthupatos", rendered "deputy". Gallio was the brother of Seneca, the philosopher and tutor of Nero. He is often mentioned in the literature of that day as a cultivated, polished man of the world. Seneca speaks of his brother's residence in Achaia. The Jews made insurrection. Rose up against Paul, no doubt enraged at the success of his work. His sleepless enemies always found some occasion to stir up strife. Brought him to the judgment seat. The court of Gallio.
