Exposition of the Old and New Testament, by John Gill, [1746-63], at sacred-texts.com
Philippi was a Roman colony, and the chief city of one part of Macedonia, Act 16:12, it is by Appianus called Datos which was its original name; and by Diodorus Siculus it is called Crenidae (a), from, the fountains about it; and it took its name Philippi, from Philip king of Macedon, father of Alexander the great, who rebuilt and fortified it; near this place a famous battle was fought, and a victory obtained by Augustus Caesar and Mark Antony, over Brutus and Cassius; it is now called Chrixopolis, properly Chrysopolis, from the plenty of golden mines near it: here the apostle was directed by a vision, to go and preach the Gospel; and which was succeeded, to the conversion of Lydia, and the jailer, and their families; which laid the foundation of a Gospel church in this place, to whom this epistle is written; and which was written by the apostle when he was a prisoner at Rome, as many things in it show; for he more than once makes mention of his bonds, and of these being made manifest in Caesar's palace, and of some of Caesar's household sending their Christian salutations to this church: Dr. Hammond makes the date of this epistle to be the year 59, and Dr. Lightfoot places it in the year 60, and the sixth of Nero; the occasion of it was this, the Philippians, to whom the apostle was very dear, he being the first preacher of the Gospel to them, and the instrument of their conversion, hearing that he was a prisoner at Rome, send their minister and pastor Epaphroditus to him, to visit him, and by him a present to support him under his afflicted circumstances, and who related to him the case of this church; and at his departure he sent by him this letter; the design of which is, to express his love and affection to them; to give them an account of his bonds, and the usefulness of them, and how he was supported under them; to encourage them under all the afflictions and persecutions, they endured for the sake of Christ; to excite them to love, unity, and peace, among themselves; to caution them against false teachers, judaizing Christians, that were for joining Moses and Christ, law and Gospel, works and grace together, in the business of salvation; to exhort them to a holy life and conversation, and to return them thanks for their kind present.
