2nd Thessalonians 2:5

2 to the end that ye be not quickly shaken from your mind, nor yet be troubled, either by spirit, or by word, or by epistle as from us, as that the day of the Lord is just at hand;

3 let no man beguile you in any wise: for [it will not be,] except the falling away come first, and the man of sin be revealed, the son of perdition,

4 he that opposeth and exalteth himself against all that is called God or that is worshipped; so that he sitteth in the temple of God, setting himself forth as God.

5 Remember ye not, that, when I was yet with you, I told you these things?

6 And now ye know that which restraineth, to the end that he may be revealed in his own season.

7 For the mystery of lawlessness doth already work: only [there is] one that restraineth now, until he be taken out of the way.

8 And then shall be revealed the lawless one, whom the Lord Jesus shall slay with the breath of his mouth, and bring to nought by the manifestation of his coming;
