2 Thessalonians 2:6-8
6 And now you know what is holding him back, so that he may be revealed at the proper time.
7 For the secret power of lawlessness is already at work; but the one who now holds it back will continue to do so till he is taken out of the way.
8 And then the lawless one will be revealed, whom the Lord Jesus will overthrow with the breath of his mouth and destroy by the splendor of his coming.
