"8And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: 9Even him, whose coming is after the working of Satan with all power and signs and lying wonders, 10And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. 11And for this cause God shall send them strong delusion, that they should believe a lie: 12That they all might be damned who believed not the truth, but had pleasure in unrighteousness."
