Young's Literal Translation
The Man of Sin
1And we ask you, brethren, in regard to the presence of our Lord Jesus Christ, and of our gathering together unto him, 2that ye be not quickly shaken in mind, nor be troubled, neither through spirit, neither through word, neither through letters as through us, as that the day of Christ hath arrived; 3let not any one deceive you in any manner, because — if the falling away may not come first, and the man of sin be revealed — the son of the destruction, 4who is opposing and is raising himself up above all called God or worshipped, so that he in the sanctuary of God as God hath sat down, shewing himself off that he is God — [the day doth not come]. 5Do ye not remember that, being yet with you, these things I said to you? 6and now, what is keeping down ye have known, for his being revealed in his own time, 7for the secret of the lawlessness doth already work, only he who is keeping down now [will hinder] — till he may be out of the way, 8and then shall be revealed the Lawless One, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the manifestation of his presence, 9[him,] whose presence is according to the working of the Adversary, in all power, and signs, and lying wonders, 10and in all deceitfulness of the unrighteousness in those perishing, because the love of the truth they did not receive for their being saved, 11and because of this shall God send to them a working of delusion, for their believing the lie, 12that they may be judged — all who did not believe the truth, but were well pleased in the unrighteousness.
13And we — we ought to give thanks to God always for you, brethren, beloved by the Lord, that God did choose you from the beginning to salvation, in sanctification of the Spirit, and belief of the truth, 14to which He did call you through our good news, to the acquiring of the glory of our Lord Jesus Christ; 15so, then, brethren, stand ye fast, and hold the deliverances that ye were taught, whether through word, whether through our letter;
16and may our Lord Jesus Christ himself, and our God and Father, who did love us, and did give comfort age-during, and good hope in grace, 17comfort your hearts, and establish you in every good word and work.
