A.T. Robertson Commentary Acts 17:12

"Many of them therefore believed; also of the Greek women of honorable estate, and of men, not a few." — Acts 17:12 (ASV)

Many therefore (Πολλο μεν ουν). As a result of this Bible study.

Also of the Greek women of honourable estate . The word Hελληνις means Greek woman, but the word γυνη is added. In particular women of rank (ευσχημονων, from ευ and εχω, graceful figure and the honourable standing) as in 13:50 . Probably Luke means by implication that the "men" (ανδρων) were also noble Greeks though he does not expressly say so. So then the Jews were more open to the message, the proselytes or Godfearers followed suit, with "not a few" (ουκ ολιγο) real Greeks (both men and women) believing. It was quick and fine work.
