Expositor's Bible Commentary Commentary Acts 17:4

"And some of them were persuaded, and consorted with Paul and Silas, and of the devout Greeks a great multitude, and of the chief women not a few." — Acts 17:4 (ASV)

“Some of the Jews were persuaded,” but the greater number of those who responded positively to Paul’s preaching in the Thessalonian synagogue were “God-fearing” Greeks and “prominent women” (i.e., women of high standing in the city who were the wives of the principal citizens). The Jason mentioned in v.5 as Paul’s host was probably one of the Jewish converts; Aristarchus and Secundus, identified as Thessalonians in 20:4, may have also been converted at this time.
