Lyd’ia, the first European convert of St. Paul, and afterward his hostess during his first stay at Philippi. Acts 16:14, 15; also 40. (a.d. 47.) She was a Jewish proselyte at the time of the apostle’s coming; and it was at the Jewish Sabbath-worship by the side of a stream, ver. 13, that the preaching of the gospel reached her heart. Her native place was Thyatira, in the province of Asia. ver. 14; Rev. 2:18. Thyatira was famous for its dyeing works; and Lydia was connected with this trade, as a seller either of dye or of dyed goods. We infer that she was a person of considerable wealth.
