Revelation 1:10: “I" [John] "was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet,”

Revelation 1:11: “Saying, I am Alpha and Omega, the first and the last: and, What thou seest, write in a book, and send it unto the seven churches which are in Asia; unto Ephesus, and unto Smyrna, and unto Pergamos, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea.”

Note: The judgments of the churches are in Revelation chapters 2 and 3.
