'Seven Churches' in the Bible

John to the seven churches which are in Asia: Grace to you and peace, from him who is and was and is to come; and from the seven Spirits which are before his high seat;

Saying, What you see, put in a book, and send it to the seven churches; to Ephesus and to Smyrna and to Pergamos and to Thyatira and to Sardis and to Philadelphia and to Laodicea.

The secret of the seven stars which you saw in my right hand, and of the seven gold vessels with burning lights. The seven stars are the angels of the seven churches: and the seven lights are the seven churches.
