Revelation 2:21-23

YLT(i) 21 and I did give to her a time that she might reform from her whoredom, and she did not reform; 22 lo, I will cast her into a couch, and those committing adultery with her into great tribulation—if they may not repent of their works, 23 and her children I will kill in death, and know shall all the assemblies that I am he who is searching reins and hearts; and I will give to you—to each—according to your works.
