2 Thessalonians 2:3

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 Thessalonians 2:9-11

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. 2:11 Consequently God sends on them a deluding influence so that they will believe what is false.
