Revelation 2:21-23

21And I gave her time that she should repent, and she will not repent of her fornication.

22Behold, I cast her into a bed, and those that commit adultery with her into great tribulation, unless they repent of her works,

23and her children will I kill with death; and all the assemblies shall know that I am he that searches [the] reins and [the] hearts; and I will give to you each according to your works.
