Revelation 3:7

“And to the angel of the church in Philadelphia write, etc.] Of the city of Philadelphia, (see Gill on “<660111>Revelation 1:11”); According to the Apostolical Constitutions f108, one Demetrius was ordained bishop of this church by the Apostle John; but this is not to be depended on; nor is it known who this angel was: however, certain it is there was a church in this place in the “second” century, in the times of Ignatius, who wrote an epistle to it, and which then had a bishop or pastor over it, whom he mentions f109, though not his name. And in the same century twelve Philadelphians suffered martyrdom at the same time Polycarp did f110; and in the “third” century a church remained in this…”

“Philadelphia--in Lydia, twenty-eight miles southeast of Sardis, built by Attalus Philadelphus, king of Pergamos, who died A.D. 138. It was nearly destroyed by an earthquake in the reign of Tiberius [TACITUS, Annals, 2.47]. The connection of this Church with Jews there causes the address to it to have an Old Testament coloring in the images employed. It and Smyrna alone of the seven receive unmixed praise. he that is holy--as in the Old Testament, "the Holy One of Israel." Thus Jesus and the God of the Old Testament are one.

“And to the angel of the church in Philadelphia - See the notes on Revelation 1:20. These things saith he that is holy - This refers undoubtedly to the Lord Jesus. The appellation holy, or the holy one, is one that befits him, and is not infrequently given to him in the New Testament, Luke 1:35; Acts 2:27; Acts 3:14. It is not only an appellation appropriate to the Saviour, but well adapted to be employed when he is addressing the churches. Our impression of what is said to us will often depend much on our idea of the character of him who addresses us, and solemnity and thoughtfulness always become us when we are addressed by a holy Redeemer. He that is true - Another characteristic of the…”

“The holy one, the true one - Two great and glorious names He that hath the key of David - A master of a family, or a prince, has one or more keys, wherewith he can open and shut all the doors of his house or palace. So had David a key, a token of right and sovereignty, which was afterward adjudged to Eliakim, Isa 22:22. Much more has Christ, the Son of David, the key of the spiritual city of David, the New Jerusalem; the supreme right, power, and authority, as in his own house. He openeth this to all that overcome, and none shutteth: he shutteth it against all the fearful, and none openeth. Likewise when he openeth a door on earth for his works or his servants, none can shut; and when he…”

“3:7-13 The letter to the church in Philadelphia encourages Christians who seem to be weak and powerless to realize that their true strength is in Christ. This comforting message includes no words of disapproval. The Kingdom of God does not depend on human strength or wisdom but on God’s power and authority. 3:7 Philadelphia was situated in the foothills of the Timolus Mountains, open to fertile plains in the east. The city repeatedly experienced severe earthquakes that left it weak and impoverished. • This verse quotes phrases from Isa 22:22. • key of David: Jesus the Messiah is successor to David’s royal line. As the gatekeeper of heaven, Jesus has authority to open and close the way to…”

“to the: Rev 1:11, Rev 2:1 Philadelphia: Philadelphia, so called for its founder, Attalus Philadelphus, still exists in the town called Allahshehr, "the city of God," "a column in a scene of ruins." It is situated on the slopes of three or four hills, the roots of mount Tmolus, by the river Cogamus, twenty seven miles ese from Sardis, about long. 28 degrees 40 minutes, lat. 38 degrees 23 minutes.
