2 Thessalonians 2:3-4

3Let not any one deceive you in any manner, because [it will not be] unless the apostasy have first come, and the man of sin have been revealed, the son of perdition;

4who opposes and exalts himself on high against all called 1God, or object of veneration; so that he himself sits down in the temple of 2God, shewing himself that he is 3God.
