Charles Ellicott 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)

And some of them . . .—Obviously only a few in comparison with the "great multitude" of the Greek proselytes of the gate. The Thessalonian Church was predominantly Gentile, some of its members apparently won from idolatry without passing through Judaism (1 Thessalonians 1:9). Some good manuscripts, indeed, express this by reading, devout persons and Greeks.

Of the chief women not a few.—These, like the women in the Pisidian Antioch (Acts 13:50), had probably come previously under Jewish influence. Here, however, they were attracted by the higher teaching of the Apostles.
