Revelation 1:9-11

9 I am John, your brother, and as a follower of Jesus I am your partner in patiently enduring the suffering that comes to those who belong to his Kingdom. I was put on the island of Patmos because I had proclaimed God's word and the truth that Jesus revealed.

10 On the Lord's day the Spirit took control of me, and I heard a loud voice, that sounded like a trumpet, speaking behind me.

11 It said, "Write down what you see, and send the book to the churches in these seven cities: Ephesus, Smyrna, Pergamum, Thyatira, Sardis, Philadelphia, and Laodicea."
