The man of lawlessness, or the man of sin, [Greek:] ὁ ἄνθρωπος τῆς ἀνομίας is described as the "son of destruction", or "the one who brings destruction" NLT. The Apostle Paul, in 2 Thessaloinians 2:3-12, may have been referring to the Antichrist.
- 2 Thessalonians 2:1-12
 However, brothers, concerning the presence of our Lord Jesus Christ+ and our being gathered together to him,+ we ask you 2 not to be quickly shaken from your reason nor to be alarmed either by an inspired statement*+ or by a spoken message or by a letter appearing to be from us, to the effect that the day of Jehovah*+ is here.
 Let no one lead you astray in any way, because it will not come unless the apostasy+ comes first and the man of lawlessness gets revealed, the son of destruction.+ 4 He stands in opposition and exalts himself above every so-called god or object of worship,* so that he sits down in the temple of God, publicly showing himself to be a god. 5 Do you not remember that when I was still with you, I used to tell you these things?
 And now you know what is acting as a restraint, so that he will be revealed in his own due time. 7 True, the mystery of this lawlessness is already at work,+ but only until the one who is right now acting as a restraint is out of the way. 8 Then, indeed, the lawless one will be revealed, whom the Lord Jesus will do away with by the spirit of his mouth+ and bring to nothing by the manifestation+ of his presence. 9 But the lawless one’s presence is by the operation of Satan+ with every powerful work and lying signs and wonders*+ 10 and every unrighteous deception+ for those who are perishing, as a retribution because they did not accept the love of the truth in order that they might be saved. 11 That is why God lets a deluding influence mislead them so that they may come to believe the lie,+ 12 in order that they all may be judged because they did not believe the truth but took pleasure in unrighteousness.
