Revelation 2:12-13

12‘Write this to the angel of the church at Pergamum: “This is the message to you from the one who has the sharp sword with two edges.

13I know where you live. It is the place where Satan sits as king. But you still continue to trust me. You remember Antipas who spoke a clear message about me. Because of that, some people in your city killed him. You saw what happened to him, but you continued to believe in me. You still serve me, even there where Satan lives.
