King James Bible

1. (land of Lydus), a maritime province in the west of Asia Minor bounded by Mysia on the north, Phrygia on the east, and Caria on the south. It is enumerated among the districts which the Romans took away from Antiochos the Great after the battle of Magnesia in B.C. 190, and transferred to Eumenus II. king of Pergamus. Lydia is included in the "Asia" of the New Testament.
2. the first European convert of St. Paul, and afterward his hostess during his first stay at Philippi. (Acts 18:14,15) also Acts 18:40 (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; (Revelation 2:18) Thyatira was famous for its dyeing works; and Lydia wars connected with this trade, as a seller either of dye or of dyed goods. We infer that she was a person of considerable wealth.
3. In "Baal-hazor which is by Ephraim" was Absalom's sheepfarm, at which took place the murder of Amnon, one of the earliest precursors of the great revolt. (2 Samuel 13:23) There is no clue to its situation.
4. a city "in the district near the wilderness" to which our Lord retired with his disciples when threatened with violence by the priests. (John 11:54)
