2 Thessalonians 2:3-4

2:3 Let no one deceive you in any way. For that day will not arrive until the rebellion comes and the man of lawlessness is revealed, the son of destruction. 2:4 He opposes and exalts himself above every so-called god or object of worship, and as a result he takes his seat in God’s temple, displaying himself as God.

2 Thessalonians 2:8-10

2:8 and then the lawless one will be revealed, whom the Lord will destroy by the breath of his mouth and wipe out by the manifestation of his arrival. 2:9 The arrival of the lawless one will be by Satan’s working with all kinds of miracles and signs and false wonders, 2:10 and with every kind of evil deception directed against those who are perishing, because they found no place in their hearts for the truth so as to be saved.
