'One' in the Bible

Unceasing thanks are due from us to God on your behalf, brethren. They are appropriate because your faith is growing greatly, and the love of every one of you for all the others goes on increasing.

Let no one in any way deceive you, for that day cannot come without the coming of the apostasy first, and the appearing of the man of sin, the son of perdition, who sets himself against,

and then the Lawless one will be revealed, whom the Lord Jesus will sweep away with the tempest of His anger, and utterly overwhelm by the awful splendour of His Coming.

The appearing of the Lawless one will be attended by various miracles and tokens and delusive marvels--for so Satan works--

But the Lord is faithful, and He will make you stedfast and will guard you from the Evil one.

and if any one refuses to obey these our written instructions, mark that man and hold no communication with him--so that he may be made to feel ashamed.
