Matthew Poole and continuators on Acts 16:13

13 And on the sabbath we went out of the city by a river side , where prayer was wont to be made; and we sate down, and spake unto the women which resorted thither.

In those places where there were not enough to build a Synagogue, or could not obtain leave to do it, the Iews in those Countries chose more private places to meet in, which usually were near Rivers, or by the Sea-side, removed from the noise and observance of the Multitude; and these places were called Proseuches, from the Prayers which were usually made there; and to one of these, Paul and the rest went, taking that occasion to meet with them whom they might preach the Word of Life unto.

The Women are here named, as being more numerous in those Oratories, or such as most willingly heard and attended unto what was spoken.
