All the Greeks; not the converted Greeks, though St. Austin thought they beat Sosthenes, as an enemy to Paul, (yet surely they had not so learned Christ), but the unbelieving or Gentile Greeks, who cared for neither Paul nor Jews, but favoured Gallio, who would have them driven away. Sosthenes; some think him to have been the same with Crispus, Acts 18:8; others, to have succeeded him in that office; and some think that he was chief ruler of another synagogue (for in great cities there might be more than one); and others, that there might be several called chief rulers over one and the same synagogue. Gallio cared for none of those things; either slighting the Jews and all their controversies, or prudently declined intermeddling with them.
