New Defender's Study Bible Notes
16:13 wont to be made. Paul normally went first to a local synagogue when he arrived in a new city, but apparently there was none in Philippi. Since a group of only ten active men was required to constitute a synagogue, there must have been only a very small Jewish population there. The only such religious activity on the weekly Sabbath was apparently a ladies’ prayer meeting, so that was where Paul headed. Despite this unpromising beginning, this gathering became the nucleus of the first Christian church in Europe.
16:14 Lydia. Lydia was not a Jewish woman but, as a native of Thyatira, had evidently attended the synagogue there and become one of the worshippers of God in their congregation. When she heard the gospel, the Lord opened her heart and she believed—another example where divine election and human freedom are naturally juxtaposed.
16:15 her household. Lydia’s “household” consisted apparently of her servants. There is no indication that she was either married or a widow.
