2 Thessalonians 2:3, 10-12

let no man beguile you in any wise: for it will not be, except the falling away come first, and the man of sin be revealed, the son of perdition

and with all deceit of unrighteousness for them that perish; because they received not the love of the truth, that they might be saved. And for this cause God sendeth them a working of error, that they should believe a lie: that they all might be judged who believed not the truth, but had pleasure in unrighteousness.
