2 Thessalonians 2:3

3 Let 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;

2 Thessalonians 2:3 In-Context

1 Now we beg you, brethren, by the coming of our Lord Jesus Christ and our gathering together to him,
2 that ye be not soon shaken in mind, nor troubled, neither by spirit, nor by word, nor by letter, as [if it were] by us, as that the day of the Lord is present.
3 Let 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;
4 who opposes and exalts himself on high against all called God, or object of veneration; so that he himself sits down in the temple of God, shewing himself that he is God.
5 Do ye not remember that, being yet with you, I said these things to you?
