'Seven Churches' in the Bible

John to the seven churches which are in Asia: Grace to you, and peace, from the one who is, and who was, and who is coming; and from the seven Spirits which are before his throne;

saying, Write what you are seeing in a book, and send it to the seven churches; unto Ephesus, and unto Smyrna, and unto Pergamum, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea.

and the mystery of the seven stars which you saw in my right hand, and the seven golden candlesticks. The seven stars are the angels of the seven churches: and the seven golden candlesticks are the seven churches.
