'Away' in the Bible

These will pay the penalty of eternal destruction from the Lord’s presence and from His glorious strength

Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;

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.

Now we command you, brothers, in the name of our Lord Jesus Christ, to keep away from every brother who walks irresponsibly and not according to the tradition received from us.

And if any man does not give attention to what we have said in this letter, take note of that man, and keep away from him, so that he may be shamed.
