Revelation 2:22-23

22Listen to this! I will cause her to suffer on her bed, so that she cannot get up. Those who join her in her sins will also suffer very much, unless they change the way they live.

23I will send a terrible illness to kill those who obey her. Then all the people in the churches will know that I look deep inside them. I know what you really want. I know what you really think. I will give each of you what is right for you, as a result of what you have done.
